Greg In The Desert

Hey. Thank you so much for your information! This is saving me a lot of money and probably my marriage (LOL!). We are BIG Florida Gator fans and we CAN NOT miss the big game on Thursday! Thanks, Cheyenne!

A technician from a big retail store where I bought it came and he cannot figure out whats wrong with it, he change the lamp and the motherboard circuit and still it did not work.The guy cannot figure it out why it is blinking red 6X. Out of my frustration, I search the problem in the internet and then I read this information. At first I’m a little bit skeptical to follow your advise but I finally do it and it works!!!!!! My kids are so happy when they saw its working. Thank you for sharing this information.

I saw the site in question which is Agoraquest(www.agoraquest.com). They have actually helped me out. The $12 isn’t just for the service bulletin. You can get up to 3 service manuals per year which is great since companies charge a rip off price of $15 for each one. Anyway, I thought I would state the other side.

Thank you! My Sony TV KDF-55WF655 55″ LCD DLP Projection TV works after replacing the thermal fuse. The Sony authorized dealer wanted $460.00 dollars to replace the G1 board what sony was telling him to do and that was not where the problem was….

Our tv went out this past Sunday and I was searching everywhere on the internet to get information about the red light blinking six times. Your post was very helpful and definitely solved our problem. Our TV works now! Thank you so much!

I have one question though…what is the purpose of removing the fan housing to gain access to the original thermal fuse if the original thermal fuse (the grey and black part) is located above the fan housing and can be disconnected without removing the fan?

Should the black part of the fuse be connected to something?

hey how r u i guess i m havin the same problem which u went thru can u plzz tell me wht is the easy way 2 replace it

hey greg thnx 4 reply bak i just wana make sure do i hav 2 take the fan off. for me 2 actually replace the thermal fuse

greg u r the man bro my tv is working fine now after changi the thermal fuse cuz of u boss i hav save so much.

hi greg 1 more question i got the same thermal fuse as u hav displ on top of the box it hav tht little electronic piece which connect 2 black wires together wht do i hav 2 do should i take off tht little electronic piece and use it the way orignal was or is there is anythi else i can do 2 it i mean how can i connect with tht harness

Greg Smith

or anyone familiar with this issue

After reading all the questions an answers about the therma fuse, here is my conclusion:

1. Un-plug the old fuse wire

2. Plug in the new wire

3. Run the new therma wire down and under the lamp housing

4. The new fuse wire does not need to be connected to the old dime shaped HI LIMIT SENSOR.

5. Let the new fuse wire lay under or near the lamp housing.

I have the sony KDF55wf655 that shows the standby light blinking six times. I took everything out, fan housing, protective panel and saw the two wires (thermal fuse) hooked up near the top of the fan housing extending down the TV near the base. The other terminal is black and goes inside a plastic case located near the middle of the TV mounted at the base. What is the black terminal of the fuse connected to?. Any help or tips connecting the thermal fuse, I’ll appreciate it.

Thanks

Leo

Greg Smith

Should the new therma fuse wire follow the same path as the old wire or is there a better route?

Thanks Jerry. I see the thermal fuse. What I don’t see is the part that enters a little plastic box at the base of the TV. The two black wires that do in there, are they connected to anything?. I tried to pull them out and they move but I just don’t want to force them. Sould I remove the screw that the plastic box has?. I see that one terminal is plugged to a set of cables but the other terminal is my problem. Please advice?

Thanks again

Leo

Thanks for sharing this Greg. People like you make the internet an invaluable tool. When our screen crashed, we called Sears service. The technician told us over the phone it was the lamp, it was easy to replace (a kindergartner could do it), and he was sending us one. Well it ain’t easy to replace if you don’t know where it’s at or how to remove it. After I found the owner’s manual on the internet and read the instuctions….it was easy. You’d think they would put the replacement instructioons in the box with the part. Power up…….nada! 6X blinking red light! So now I know what the problem is and the wife is BACK on the phone trying to get a tech to come out and fix it (warranty work). We’ll see if the techie actually know what the problem is. Thanks again for sharing.

And ricky……just a suggestion. You may find it helpful to write coherently when you expect answers to questions.

You’re right Mike, this Greg is something else, sharing all the info. I really appreciate that and sure many others. I’m still waiting for the part to arrive, this sony guys. Mike, it would be nice if you actually see the tech perform the repair, and then if you can share your thoughts. My tv is out of warranty, don’t even try to call tech. Thanks in advance and all of you that are posting here.

Thanks Greg for putting the fix for the 6 blinking lights on your website. I received the thermal fuse today and put it in. Now we are back to watching our big screen TV. A little bit of advice, Don’t bother calling Sony Technical Support. They will tell you to unplug the TV and then plug back in. If that doesn’t fix your problem call a TV repairman. I don’t the the person that I talked to had ever opened that back of a TV Set. If I have other problems with this set, I will be back to the internet to hopefully find more good advice. Thanks again Greg.

Greg, you’re the man!!!
Thanks a lot for having this up!
$11.90 on eBay and your intructions and BAMMMM!!! problem solved!
Thank you very much!
Take care,
Bob.

Thank you Greg for the nice post. My TV died yesterday with the famous 6x blinks. I just got out of 4 years extended warranty so had to schedule a service call with Sony for Monday. Just saw you post, ordered the thermal fuse and cancelled the appointment. Will let you know once I get the fuse and replace it.

Thanks again,
Nary

Followup report: (Sorry I’m late) Well the repair tech showed up, did a little trouble shooting with some help over the phone to HQ. Turns out it WAS the thermal fuse just like Greg said. What he did to confirm this was jumper across the fuse to see if the TV worked (it did). However, he didn’t bring the part with him (even though my wife told them over the phone about the blinking light trouble code). So he had to come BACK to fix it. Only took a few minutes each trip and didn’t cost us anything thanks to warranty (except inconvienience of no TV). I’m confident I could have fixed the problem myself thanks to Greg’s great directions and pictures here. Good luck to all.

Thanks for taking the time to post these instructions. It’s people like you that make the “free” internet work!

Greg you are a lifesaver. I thought I had a burnt lamp or something major. I just got done replacing the thermal fuse. Best 10 dollars I have ever spent!

Hello Greg

Great info but i am having some issues; i ordered the part like you said and removed back panel as well as fan housing and still don’t see thermal fuse as pictured above. Don’t know what else to remove

thanks

i suppose one reason is my tv is kdf-55wf655 and yours is a 60 inch. I just figured it would be in the spot as yours because of the successful replacement posts with my model number

Hello Greg,

Thanks so much for the interest in my problem; here are the pictures. Hopefully I can go back to enjoying my TV

Thanks Greg and all the posts. TV is up and running after replacing the thermal fuse. Just like you said, unplug the old one, connect the new one and run it along the location of the old fuse (don’t need to completely remove the old fuse). Just follow its path and that’s it. Thanks to all!!!

Greg you are so the Man! I ordered my thermal fuse from the amazon link and could not wait to put it in. My TV stopped working when my girlfriend turned off the power strip the TV was plugged into so the tv was not able to cool off with the fan. I forgot to tell her to wait for the fan to shut down then turn off the power strip. I didn’t yell at her or get mad at her she was trying to help. I accidentally turned off the power strip before but if you turn the power strip back on and the tv back on quickly and let the picture come back then turn it off and let the fan cool it down after the fan shuts down you can turn off the power strip and it will be ok. I turn off my power strip so my energy bill won’t be high. my utillity bill is usually under $30 cause i unplug the things i am not using. I leave my aquarium on and my fridge on separate plugs and my alarm clock with my dsl computer modem and my tv are now on the same strip with my answer machine on all the time. I have my computer on a separate strip and always unplug it so the transformers won’t eat up power when i’m gone. it might sound green but i call it saving money
this is just to be helpful i’m not a tech, but I do love my 2005 Sony 60″ LCD TV
Thanks Greg You Rock Cubed!

Thanks for the info…saved me lots of $$$!!!

Hi Greg, I just ordered the fuse from Amazon, I am a hacker but I hope this works… Thanks

Hello Greg,

My tv is finally working; I had a tv repair guy intall thermal fuse. It required him taking out the light engine to position the fuse closer to the bulb. There is a clip on the back of the tv where the fuse plugs into which instantly fixed the tv issue; but in order for the fuse to work they pulled out the light engine and that was that. So people wth KDF-55wf655 listent to greg buy the fuse from Sony and you can check by unplugging a little harness that has a white and black wire with the same connector as thermal fuse

OKAY WELL AFTER RESEARCH WE HAD CAME ACROSS YOUR PAGE WITH PHOTOS , WE REPLACED THE FUSE BACK IN NOV 08, ABD IT WENT OUT AGAIN, ORDERED THE PART CAME IN AND CHANGED IT OUT , WELL THE TV WONT COME ON. ANY SUGESSTIONS, ALSO IF SOMEONE COULD TAKE A PIC OF THE BACK OF YOUR TV AND SEND IT TO ME CAUSE I HONESTLY THINK THAT MY HUBBY PULLED OUT ANOTHER WIRING FROM SOMEWHERE AND SO MY BLAME IS ON HIM, ITS A THIN BLACK WIRE THAT RUNS OT THE BOARD UP TOP AND I DONT KNOW WHERE NOW SINCE ITS DANGLING,PLEASE HELP

Thanks alot Greg! Ordered my part, took off the stuff you said, and replaced with a new thermal fuse and my TV is back up and running. Just remember to connect any wires you may have taken off when dissasembling the back of the TV. Tv did not work first time when I plugged it back in due to taking off a ground wire on the metal fan housing when disassembling. Connected it back on and tried the TV again and its back to working great again. Go Brewers!!!

Plain and Simple! I read this posting, called Sony and orderd the part for $4.50 plus 2.50 shipping. Thats $7.00 total. I followed Greggs instructions. Remove back panel, remove the fan, unplug the heat thing at the top, feed the wire down, wrap it around the old one and your done. Wa La,,I saved over $400.00 on service.

Thanks Gregg-

You are the man!!!! $12.70 and hoping I don’t curse the job but, as a great American once said “Mission Accomplished” (I really hope it works out better for me than it did for the last guy to say that)

Thank you for the writeup. I had worked out that 6 blinks meant replace the fuse, and ordered the fuse (and a spare)- and when it showed up I began to doubt that I had the right part. The pictorial gave me the confidence to just open the case up and clip it in and thread it around- and ‘Lo, there was light, and it was good.

Greg: Thanks for the info.
I have a KDF 60XS955 and the thermal fuse is compatible. (part number 191002393 with shipping arround 8.80 from sony). As soon the fanhousing is removed is easy to identify the conector.(gray and white cables on top )
I followed and runs to the lamp housing easy to see it from the front The lamp has to be removed to have sort of space to reach the tip of the fuse with a flat long nose pliers and desmount it run your new thermal fuse cable and is done I did not leave the old one. This chasis or model is easy to removed it has like a zig zag cable holder from thebottom frame easy to remove with a flat screw driver.
Again Greg Thank you .

HI GREG,

THIS IS EXACTLY WHAT’S GOING ON WITH MY TV. THEY QUOTED ME 300.00 PLUS TO COME OUT AND FIX IT. ONE QUESTION, I WENT TO AMAZON AS YOU SUGGESTED AND THERE IS ONLY ONE THERMAL FUSE TO ORDER. IS THIS THE CORRECT ONE? I HAVE THE KDF 55WF655 MODEL AND CAN NOT SEEM TO FIND THE FUSE ANYWHERE ELSE ONLINE. I AM ASSUMING THIS IS A UNIVERSAL FUSE AND WILL WORK. ANY ADVICE WOULD BE APPRECIATED. THANKS SO MUCH, TAM

MY SON AND I JUST FIXED OUR SONY AFTER READING YOUR SITE ON MONDAY AND ORDERING THE THERMAL FUSE FROM SONY. WE HAD IT DONE IN ABOUT 15 MINUTES–THANKS SO MUCH FOR THE TIPS. THE REPAIR COMPANY QUOTED ME $300.00 TO DO A 15 MINUTE JOB. ALWAYS CHECK THE INTERNET FIRST!!! THANKS GREG! ANYONE CAN DO THIS.

I have sony KF-50WE610. I had 6 blinking and did replaced the thermal fuse. Unfortunately problem still exists. Are there any other second fault that I can tackle? Appreciate any help

Thanks

Greg,
thanks for the info.
I have the KDL-E60A20 bought in 2005 at Costco. my problem actually turn on & off – 5 red blink. I purchased a new bulb & the thermal fuse from Sony. When I opened the rear cover & removed the fan housing, I found that my Sony is already came with the new thermal fuse. It was routed around the square dark grey housing for the fuse. the 2 stands for the old fuse are there, but the round metal part is not installed. The end sensor goes into a small plastic housing (on the left side). So I only installed the new bulb. The TV is working just fine! Greg do I need to reset the lamp timer? do you know how?.

Hey Greg, I have a big screen SONY KDF-42WE655, out of no where the power just shut off and the Lamp light just keeps Blinking ready continuously, I left it unplugged overnight and tried it again the next morning. Same result, the flashes green for a while then straight back to solid red and the Lamp light blinks red. Any ideas on what is going on, do you think i need a new Lamp Bulb?

Thank you very much!!!, I ordered the part from sony, replace it and it works immediately, I have the KDF-60XS955

Hi Rodrigo (FL),

What was the problem you had and what part did you replace? Please share in detail – Thanks

The part number in question is 191002393, which lists for $4.80.

I contacted Sony directly and they said they cant give out the Service Bulletin to consumers. I will go ahead and buy this part and follow Greg’s instructions. Here is another set of instructions:

Unscrew the lower rear casing (about 9 screws),disconnect the old one and replace with new fuse. Just be sure to tape off the old one to the side and tape the new one away from the lamp housing. If you’re looking at the TV from the rear, the fuse will be located at the lower right side on top of the lamp housing; it’s too easy.

For those of you who have pets or a lot of dust in your houses, you might try this to avoid a second thermal fuse replacement. Go to the hardware store and buy some thin furnace filter material (Home Depot for about $15) and use it cover the air vents on the bottom, back side of your TV set. This will help keep the inside of the TV free from dog hair and dust that can clog your fan and render it non-operational, causing the thermal fuse to blow. This is a likely cause of many thermal fuse failures. The filter can be taped on, and is largely unnoticable from the front of the set. You’ll be amazed at how much dust and dog hair is stopped by this fix. Change the filter material before it gets totally clogged. This will keep the inside of the TV and the fan dust free. Don’t cover the fan or let it overheat.

Greg, thanks for the pics. I tore my tube apart on Saturday and I wasn’t sure I had taken out the thermal fuse until I saw your picture. I used an offset screwdriver to take it out. The plastic housing slides out to make it easier.
Again, thanks for the pics.

Thanks Greg

Another success story!

researching this on the web saved me alot of money. Had the part in 4 weeks and replaced in 30 mins. The shop I ordered the part from tried to convince me to have them do the work and diagnose. I told them I have worked with electronic devices in the past and there will no need for them.
Thanks again, will be watching the Packers in HD this weekend.

Ok, i have a kdf-e60a20 and i removed the back panel the fan and its housing and for the life of me i cannot see this thermal fuse i have the same exact tv pictured above but that little piece in the 2nd picture is not on my t.v (very frustrating) i refuse and actually cant at the moment pay $500 bucks for a tech please explain where it is more thoroughly i even went as far as removing the front panel and i still couldnt see it

Hi, I have a KDF 60XS955 and I have already replaced the thermal fuse; however, the problem continues. Any other Ideas?

Greg

I left my TV on pause (using a DVR). Evidently, this can make the TV hotter than normal. Consequently, six blinking lights later. I came across your post and you saved me $200. I am now cancelling the Sears tech who is supposed to come by in two days to fix the TV. I was able to do the repair for less than $35 (I expressed shipped the fuse).

Looking at your pictures helped me. I started taking off the top part of the TV but finally figured out that it is the bottom part that you were referring too. I took off the silver plate then the fan. I looked at your pictures and routed the wire around the dime looking thing. TV works perfectly.

Thanks a lot. Graham

Hello Greg Smith, Thank you for your helpful instructions, otherwise I was planning to dump it for recycle. I was able to fix the thermal fuse on KDF-55SX955. The instructions are little different as I needed to remove optical block too. Thanks again!

Please let me know if anyone of you need instructions to replace thermal fuse KDF-55SX955 or KDF-60SX955.

Many, many thanks for this post. I stumbled upon your site when researching the six blinks from my KDF55WF655. Less than a week later, my husband and I repaired it ourselves and saved a ridiculous amount of money.

You, sir, are awesome.

THANK YOU for all the comments and recommendations on how to replace the fix the 6x flashing lights of death on my Sony TV KDF55WF655. It took 2 attempts following Sony shipping a defective part. Thankfully, I read somewhere that a tech linked the connections to prove that the Thermal Fuse was faulty. Our TV is back up and running today after recieving the 2nd fuse.

Again, thank you all! You have saved me $$$$

Hi Greg, I want to thank you so much…..I was researching the six blinks when I came across your site, I sent for the fuse and my husband changed it and thankfully it worked. It seems you have helped a lot of people with your knowledge, and I think that is so kind of you to help people u dont know. Again, THANKS!!!!!

we got bit by the blinking light bug tonight; I have the KDF-60xs955 originally was blinking 10 times; unplugged the unit and plugged back in and is now blinking 6 times..very glad to see this posting in hopes that it will save us some money…going to order part tonight…i’ll be in touch….and thanks greg for taking the time to share your info.

@nice and quiet but i guess i need to fix it anyway
replaced fuse and is working….i was able to remove old fuse completely on my model…all is well….again thanks for the info.

I would like to state here after further research on this problem; i was very curious as to why the thermal fuse would blow and there are a number of reasons. However in my case my TV was full of dust. Air was restricted from getting to the bulb housing. You would think that the fan in the rear of the TV would be the one cooling it but it is not, that my friends is the exhaust fan.(Sucks air out.)i read another post here and someone had recommended using a make shift air filter on the rear of your tv, do not do that. Your fan that cools it is a much smaller fan that is mounted right above the bulb housing.(squirrel cage fan)or(intake fan)Runs at a much slower rate;and is very easy to clog. once clogged it will not move and thus causing the TV to overheat. once you get to it you can try to blow it out and reuse however if you have went through the trouble to get to it you had might as well replace it and is recommended. Your indication that this is your problem will most likely be that there will be “plastic browning” around the walls of the bulb compartment and possible cracks at the base of the compartment. And a very burnt smell. To make matters worse you can’t get to this fan without removing the optical block. That is why this fan fails due to neglect. the fan itself sells for 30.00 from Sony and if your fuse has blown be aware it may blow again in the future if the fan issue is not resolved. Apparentely if you are going to be an owner of this Tv might as well plan on servicing it properly to keep it going and better yet safe. Oh and by the way don’t bother trying to remove the top portion of the rear cover it will get you no where there will be another cover that is not so easy to remove. I also know that some people are worried that the TV will harbor live electrical current even without the TV plugged in. You will not have to worry about getting shocked here. The only part that is high voltage is the optical block and it will discharge all current within 30 seconds of unplugging the TV set.

@Rowan Smith
Hi Rowan,
I have the same TV as yours, KDF55WF655, with the same 6 blinks problem. Did you use the same part as on Amazon, Part no. 191002393, as posted by Greg? Please share the part number. Also, if you can share the steps I would appreciate it.

Thanks in advance.

Greg, thanks for this information and leaving this website up and available. My KDF-60XS955 just blew out with the 6 blinking lights last night while watching tv. I managed to find a local TV repair place that had the part in stock. Installed it and was back up and running in last then a day. Thanks again. You saved me a ton of money for sure.
