Question about Sony Grand WEGA KDF-55WF655 36" Rear Projection HDTV
Hi i have 50" sony rear projection tv problem is it doe'nt turn on when i switch the power button all i get is blinking red light pls help!
I was very happy to see poolmvp1's solution . We already bought the manual and ordered the part.I just want to make a correction on the manual website .It's servicemanuals.com ,not servicemanual.com...It took me a while to figure it out. I just hope it will work for our TV, I don't like someone to repair my TV, who knows what they are going to break while trying to fix it ,so i think it's a great idea to do it yourself!

I purchased a service manual for $16.99 from ServiceManual.net. I downloaded the manual. Read it and you have to make note of how many times the power LED blinks red. My 55" Wega was blinking 6 times then pause then repeat.
The manual indicated it was a "Low B error, No "DD 6V" output ( G1 Board) No picture/No Sound.
The manual gave me instuctions on how to remove the G1 Board. I took it out and clean off the dust reseated the G1 Board, still the same problem. I order an new G1 Board, part# A-1060-177-A from the "Partstore.com" for $186.25
Problem is fixed and I save $350 on service call.

thermal fuse. it sits below the lamp and has popped. replace with new fuse or just short (eliminating fire protection) let me know if you need instructions.

SOURCE: replaced bulb on 50 inch
Did you clean out the lamp ventilation duct in the back of the set? If it's clogged with dust you could have an overheating problem (this also kills lamps). You may need to unplug the set and remove the back cover to make sure you can evict all of the dust bunnies in the duct. Also, vacuum out all of the vent slots in the back cover. Try not to get any dust into the bulb or optics.
Safety notes: the set should have been off for at least 30 minutes before doing anything to avoid getting burned on the lamp. Do not touch the electronic circuit board, even if it is dusty (just use your breath to blow the worst of the dust off the circuitry). Touching the circuit board or using a vacuum cleaner on it can cause damage by static electricity charging. There is also a possibility of getting an electric shock from capacitors still holding a charge. Normally, this stuff is nowhere near the lamp ventilation hardware, so it should not be a problem avoiding it. But definitely make sure you unplug the set before doing any of this.
If this doesn't fix it, repost and we'll look for the more arcane answers.
