The timer and standby lights are blinking at the same time. TV turns on for a few seconds then turns off. Both fans turn on when the TV turns on and off when the tv turns off. Any idea what might be wrong?

I think u shall check the timer in the tv menu.

Does the led ever stop blinking? No ..well in that case generally this indicates a standby voltage problem...if all those voltages ok then the cuircit known as digital module is at fault. also make sure the lockout has not been activiated. i really dont think it could but to unlock hold menu button down for 10 seconds. After all that i believe it would be a bad digital module

There are particular blinks meaning on sony TV. I can give you the problem from your sony tv if you specify or count how times the LED flashed.

colour wheel issues and defective lamp replacing lamp and light engine color wheel cos its worn out

Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

you do have a deffective crt

4 times blink error shows that any FAN is not running in TV as there are 4 fans in this TV.
Please check fan connectors and make sure all are plugged securely.

after holding down the menu and device the led will blink a two digit error code such as 3 blinks pause then 4 blinks then repeat that sequence a couple of times. Need that blink code to help let you know whats going on. The 34 code means lamp abnormality which translates to the power Pwb capacitors have most likely failed.
