SOURCE: sony projection tv no power
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.

SOURCE: TV won't turn on.
I know exactly what the problem is. The protection door for the light is probably damaged by the heat of the lamp. The door has a little tab that indicates the cover is on. I had to fix mine by putting a screw; elongated the tab. Since then no problem... (I had the issue at least 3 or 4 times a day and I kept on re-tightening the door/cover)
Hope that helps

3 times means Lamp and 6 means you have lost a voltage. You may have a thermal fuse blown.
This set has a common trouble with overheating caused by the drum fan located on top of the lamp housing clogged up with dust. When the lamp is getting old it runs hotter and that combined with the fan being clogged the thermal fuse blows. You must replace the lamp and thermal fuse. You must also clean out or replace the lamp fan. This drum type fan should be cleaned out every year or two depending on the environment.

There is a problem with one or two of the diodes on the G board.
Zero Crossing Detector 9 times 9:0 or 9:1
Probable cause • D6116 or D6301 is open (G Board)
symptom • No picture
I hope this helps and good luck!
