Samsung 760V TFT LCD monitor problem

[jbclem]

My Samsung SyncMaster 760V LCD monitor, 4 months out of warranty, is developing a
problem. Sometimes the upper third of the screen will be in shadow, I can barely see
through it. Sometime the entire screen will black out, or when I turn it on in the
morning the screen will be black. So far the cure (temporary) has been to unplug the
unit and then plug it back in. This has only happened 4 times so far but I expect it to
get worse.

Can someone guess as to the cause of this type of problem, electronic component or a
problem with the screen itself? And if it is easy or hard to fix. Also, if it's too
much for me, can someone recomment a repair shop in the Los Angeles area (preferably
West Los Angeles but I'm not that picky).

Thanks, John

Forgot to mention, this is a 17" monitor.

Yes, seen this before. The cause is either a bad CCFL driver
transformer or (more likely) one or more defective CCFL tubes.

The cure is to replace all the tubes with new ones of the same diameter
and length, this should work well.
