SyncMaster 740N problem

11-17-2009, 07:04 AM

My SyncMaster 740N will power up but only the top quarter of the screen is visible. The bottom 3/4 contains fine horizontal lines and info can not be seem. All the caps on the circuit board look good. There are a couple of transformers on the board and they do not look burnt. Any help would be appreciated.

That is either a problem with the logic board, the connections between the logic board and the panel itself, or a bad panel. Disconnect and reconnect the ribbon cable between the logic board and the panel. Odds are a driver has failed in the panel.

For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.
