Random Turn-Off on KV-34HS420

I have the KV-34HS420. It will randomly turn it's self off. Sometimes after hours of use other times right after it is turned on. When it turns off the standby light blinks 7 times. When I turn it back on it sometimes stays on awhile sometimes turns right back off. I have tried the reset and replaced the remote batteries without sucess. Any help?
Thanks!

    I have a similar problem. it seems to revert to a standby mode only after 3 seconds from turning on. only after hours of trying to turn the power button on repeatedly, does it eventually stay on.

    I am having the same issue. My TV fades and turns off. The LED blinks 7 times.

    Has anyone successfully got this issue fixed? How much did it cost?

    Thanks

Hello there,
7 times blinks shows that Horizontal Deflection Circuit doesn't work properly.
I think, its not big fault and can be resolve in low cost at nearest Sony repair shop.

SONY TV. STANBY TIMER FLASHING


Hi Frank,

Please let me know if it has a pattern of blinks (separated by a pause) or it will flash an exact number of times. Your unit (KV-34HS420) has a built in self diagnostic software that will indicate the probable caused of the fault by flashing of the LED at the front panel.
