SOURCE: Sony Bravia 40 inches has a defect

More then likely your power supply failed. If you do not hear a click from the relay during the power up cycle then your power supply failed.

SOURCE: green light flashes for about

you can make sure all the connections that exist on the PCB Board TV is connected, if there are loose you can reconnect. Especially, usually there is often no (tin solder melts) connection between the foot pin of the components with the PCB board in a vertical section and Horizontal section.

There is another possibility it was caused by the failure of existing data in the EEPROM memory IC such as IC C2408, C2404 etc, you need to replace it


Then also you can check on the RGB Board, ensure the 3's Transistor for ( RED,GREEN and Blue ) is OK. if not you have to replace the transistor for GREEN.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

Green light, black screens, no sound, needs new battery???


The alarm is just a coincidence i suspect, green light comes on and stays on probably not the battery at fault. It would be red.
If the green light goes out and screens just flash one of your screens are at fault or a loose ribbon connection.

Monitor comes on, I can see everything perfect then goes black


"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.
