    I have the same problem. I left the room, came back in and the screen was black and no sound. Light blinks 4 times.

    I unplugged it for 12 hours. I pushed every button on remote and on cable remote. I tried changing channels -- nothing

    I was watchin' tv for before I went to bed and it all of a sudden
    turned off. I thought my wife set the sleep timer, but it
    wouldn't turn back on. I have noticed it did take a while for the
    tv to come on after hitting the power button.

    Same problem here... I was looking to upgrade anyway, but I wanted tokeep the old TV too. Anyone knows what those 4 blinks are, and how expensive is to fix?

    Thank you

    same here.... wooo strange how all our tv's (kv-27s42) seem to be dying at the same time... My guess is the power supply is shot, probably from that loud degaussing noise at every startup... but who knows... : ( only about 10 years from this one.

    I'm gonna try to scrape up 700 bucks canadian for a 42" 1080p insignia lcd..

    Same probelm here. We just upgraded to HD receiver so I thought that was the problem, but not so. My TV is exactly 9 years od. So much for paying the price for a Sony

Tele turned itself off, red light blinks 4 times then pauses and blinks 4 times again.


You can try unplugging it for a while and then plugging it back in, but according to the manual, the standby LED:
Lights up red when your TV is in PC power saving mode. If the LED blinks in red continuously, this may indicate the TV needs servicing.

Try to remove the vertical IC sometimes it become Shorted causing the B+ to drop. after removing try to switch on back check the B+ if ok and the LED not blinking then change the vertical IC.

On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

Sony shuts off after being turned on, stand by/timer light blinks


The blinking should be in a pattern of a count, pause, count. That is an indication of the problem circuit. Can you post that count please? That info will allow me to give you possible defective parts and costs for the repair.

Thanks,
Dan

Power LED blinks red


it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
