    There would be an interval of 3 seconds between light blinks, please count blinks and let me know to see what area of TV is in trouble.

25% of the time its just the power suply that goes bad.

You will need technical experience to fix. First what do you remember happening to set before it went out? Did you have color problems, or alignment problems? There are many things that could be wrong. Open startup resistors, R600-612, IC 601, C667,607,608 etc .

STANDBY TIMER IS A CONSTANT FLASHING


This older model the light should blink at turn on for 10-15 seconds before picture appears.

The set is checking for certain voltages and other things---if any are missing it will not come up.

This is like saying car will not start--the Battery? Or?

Someone would have to go inside and check voltages first and then check to see if horz or vertical drive etc.

May be too old a set as some parts for it no longer available.

Tv went blank


Does the timer/stand-by light blink at all? If so, count how many times it does. It will usually be in intervals. If it isn't blinking, and you have nothing on the screen, you might have a problem with the "G" Board, part # A1316499A.

Picture went off still had sound then i turned off at panel now only red timer/standy stays lit sony 61" projection


First plug in again and look at led light, the amount it blinks tells what is wrong. Then if it stays lite it tells something also. You can try Display-channel 5-volume +- Power(service mode). Then Channel 8-enter(test reset). If this doesn't work then you will have to replace somethings like F601, R607, Q601, IC601, R612, VDR601.
