Question about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV
If there is a flashing led on front of the TV, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic chargesaccumulating on capacitors, or because of a wrong voltage read by themain chip on your monitor controller board. this started the protectioncircuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Commonfaults that can occurr suddenly are a blown capacitor on power board, a convergence IC has blown, or a faulty on Digital board.
check also the video cable, if the cableis shorting, or the connector is bad, you can get same flashing statebecause of the video cable.
Check also connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.
