Having problems with your Sceptre X20G-Naga II 20.1" Flat Panel LCD Monitor ?

Sceptre X20G Naga II 20.1" Widescreen monitor

\015 The display driver board in the monitor is failing, according to Sceptre! The monitor stays on for a couple of minutes and then the screen goes completely black. No light around the edges at all. The Blue Light remains on, and I have to turn the monitor off and on several times before it will finally stay on all day!The part costs $100, but Sceptre will repair it for a flat fee of $75 if I bring it in!I'm thinking bad component like a capacitor or something equally as simple! I work on more complex electronics than that so I have the technical ability to repair it, but have no idea where to start looking.Anyone have this kind of problem?Thanking you in Advance,theonejrs\015

Answers :

I am working on one of these for a customer. Found leaky cap on 5 volt power supply. replaced it, still no backlight. Looked at the inverter with an o-scope and it runs for a few seconds then shuts off. I hooked a ccfl across each of the transformer secondaries on the inverter and it lit up! I believe the problem is failed ccfl units. There is plenty of voltage there to light them up, I have an rf burn on my thumb to show for it. I have not looked at the ease of dis-assembly of the display to replace the backlights. It does not look easy.
