Hi all,


Did a search and very little comes up on this model. 42" plasma.


This one is dead. power supply board and logic board have been replaced with "new" boards.


You can hear a small ticking on the PS board as if the switch mdoe cannot start up. The 5v line to the logic board is 0v. AC it getting to the PS and is being rectified. As far as I can track it down without a schematic it seems like the stand by supply is not running and there fore nothing coming out from the standby transformer to be turned into the needed 5v.


I have removed all connections from the PS board and still no 5v. Question, is there an "Enable" line for the standby 5v?


The problem occured all of a sudden while the TV was playing.


I would appreciate any help, hints or where I can get the schematic.
