Post originale di: Abrsvc ,

Testo:

It is very unlikely to have a power cord fail.  Since you report that there is no standby light either, than I would suspect  a rather catastrophic failure of the power supply board.  In order to try to find the cause, I would like to request that you post pictures of the boards inside the set.  Remove the back and take photos of the boards.

This may be a simple repair or not.  Let start with a visual examination first.  After that we’ll work on taking voltage measurements.
