Theres a thermal sensor near the lamp housing. other than that I am not aware of any other thermal fuses. There are however pico fuses solder to the circuit traces themselves on the back side of the circuit board where the runners are.

Tonight my Sony Wega KDF-42WE655 screen went black and the audio stopped, the standby light (green) blinked on and off for about 30 sec. then the screen came back on and the green light blinked 5 sec or so...


Hi,
Replace its lamp as existing lamp has been reached at end of its working hours life and need to replace to solve this issue. Please note lamp is not not broken or dead yet so you do not see lamp light on tv front.
Lamp replacement procedure is easy and written in user manual.
Please buy Sony original lamp for god picture in tv.
Thanks.

I have Sony TV model KDF-42WE655 which stopped working. No display and when powered on, the green light comes on and blinks approx 50 times and turn red (blinking red). How and what do I need to buy to fix...


Its not the green light that you should be count but the red. How many times is it blinking? Here is a quick update of the errors that are most common.

3x - Lamp switch not engaged
4x - Fans issue
5x - Lamp
6x - Thermal fuse

Sony wega problem look like im not the only one!


This sounds like your lamp failed and opened you thermal fuse. 6 blinks is open thermal fuse and that would normally only open if your lamp failed. Replacing the lamp is simple, but the thermal fuse is a very difficult repair with considerable disassembly.

ON/OFF button (red - off and on - green) flashing all the time


it is important to count the number of red flashes, if it is 5 then the lamp ballast board has failed, (part #1-468-798-14) if it is 4 then the optical block fan (# 178706511) is probably to blame, if it is 6 then the thermal fuse has gone bad..(# a1137954a)
