The CORRECT way to replace the thermal fuse is to pull the optical block out so you can get to the thermal fuse mounting plate. I would NOT suggest just letting it "float out in the open cool air" as some have suggested as this is a safety part and not installing properly could be a safety hazard

My Sony Grand Wega KDF-E55A20 will not turn on with the remote or manually. The red light flashes 6 times then off.


6 times is the lamp thermal fuse or lamp. its a thermal that sits on the bottom of the lamp area.
remove the fan and you will see the siler disk with black base cut the wires and slide the new one in on the side secure it on the old thermal and your fixed.

Screen turns off and on Sony KDF E55A20


It is symptom of dying lamp and tv requires new lamp.
Existing lamp in tv has reached to end of its life span and causing that problem. If lamp has not been replaced in last 2-3 years, just put new lamp in tv to get it back in business.
Thanks.

6 blinks of the red power light


The 6 red blinks means that the thermal fuse is blown, sony part number 191002393, which can be bought off of Sony.com for about $5. You will have to remove the back cover, remove the OU bracket (It is silver with 3 ground wires connected to it), remove the fan bracket with fan and then the duct fan bracket (Plastic fan duct housing). Looking between where the fan was and the lamp on the front of the TV, there is a small silver metal disk with 2 wires connected to it, which is the thermal fuse. Using an Ohm meter, you can test it. If it reads open, it is bad. Of course, you must unplug the TV first and use caution. It is a very easy fix for someone who is handy. (Approx 10 minutes)

Thermal Fuse


The thermal fuse is usually located near the lamp to prevent the lamp overhaeting and damaging the set. Sony uses two types of thermal fuses: the first type is a circular metal type, about the size of a quarter with two metal tabs for push on lugs that connect to the TV. The second type is a small plastic half moon type woth wires coming from the base. Contrary to what you might read elsewhere on this site, it is VERY IMPORTANT that you mount the new fuse where the old one was, for safety reasons.

As I responded last night the replacement of a thermal fuse is a very difficult task. The component is mounted on the lamp cage and require a great deal of disassembly. If you pull the back and the pull the center brace you will see a harness of wires. From the lamp cage you can follow either two black wires or a black and gray wire to where it has a coupling plug in said harness. Suggest a qualifier servicer to perform this task. The part can be purchase from Andrews Electronic.

Sony model KDF55WF655 blinking light 6 red flashes,no picture,no sound....
I just replaced my thermal fuse for $4.80 plus shipping handling.Took me 30 minutes to fix and 30 minutes to get dust out of TV.Take off the back of the tv about 8 screws,then remove the fan housing on the right hand side about 4 screws.If you have the new fuse you will know which wire it is ..grey and white.I found it easy to get to the other end through the front panel of the tv only 2 screws ,remove front panel and then remove cover on projection bulb and you will see the other end of the fuse clipped on.Remember to unplug tv. TV is working excellent now .
Thanks to everyone on this website.I have pictures if anyone needs them to repair it.

I want to clean the projector sitting in the back as I see that there is some dust on it. I dont know if that is a good idea or not or if it will even make a difference with the image on the screen. I want to take a pc of cotton and windex to it while I am waiting for my thermal fuse. Anyone with advice?

Sorry, I have to say it. If the bulb (LED) is shot it would have to be zero flashes :-) It's my weird sense of humour. After that I hope you'll forgive me and someone can give you some real help.
