Re: Sony 34 inch Trinitron TV

Uplug and open the cover and look for the red cable coming out of the picture tube. follow this red cable to a small board where you should see 2 black screws labled focus and screen. try turning these a notch and power on. it worked for some people but not for me...:(

Sony trinitron tube tv Standby is flashing and the tv wont turn on

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

Standby light stays on and the tv will not go on

Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem.
You question shows standby light stays On that means TV does not receive power on command from remote.
If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution.

Standby light blinks 7&6 times TV turns on and turns right off .TV repair man came and reset tv now it is doing same thing How do I reset TV

IC 8002 is the problem with your TV. Sometimes you can get the set running by unplugging it for a few minutes, or just try powering it up every so often. Once it is on it will stay on. You can leave it on until you get a repairman out to fix it.
