Tv will not stay on standby timer light flashing


On Sony the standby or red is for shutdown---

If you unplug the set and plug it back and turn it on and it repeats this look to see if the light is either constantly blinking or blinking a specific number of blinks---specific number would be an error code.

Tv flashes red then shuts itself off after only on for 3 min


I have not repaired this particular model. But sometimes there is an IC they refer to as a standby IC. It may also be known as a controller IC. I call it the powerline regulator. And in one case the older Sony Projection TV had an audio output IC with a standby built into this IC. So,this advice is refering to a standby IC. And this IC may be in another form already mentioned. Please visit a Sony Tech. The work inside a projection TV is very complicated, you will need to see the specialist. Give them this note and go from here. Let me know how they handle the repair.Thanks for asking and good luck!

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.
