Tv comes on for a few seconds then starts to blink on screen then cuts off with red light on stays on

this is a problem with the switch mode power supply unit,check for the components not functioning in this unit and replace

turn tv on the red power light comes on then goes off again

Hello! When was the last time you replace lamp in your TV? If long time ago (2+ years) - replace the lamp. If red light blinks in sequence (example 4 flashes, pause, 4 flushes, pause and so on) - then I need to know how many flushes between pauses. It is an error code. If it blinks just constantly - it is a bad lamp. Regards. Russ.

I repared some with that problem. Simply change the 2 convergence IC.

It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

unplug tv overnight. if that doesnt work the powersupply is probably bad.

Look at this link on the bottom to see what the blinks tell you.

blaNK SCREEN AND BLINKING RED LIGHT

The lamp can cause the picture to cycle without spitting out a lamp error. I'd replace the lamp and clean out the dust/dirt from fans, etc to hopefully resolve your issues.

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!
