Question about Sceptre X20g-Naga III 20.1" LCD Monitor
My Sceptre X20G-Naga III screen will go blank after I turn it on. It will stay on for 1-2 secs before it goes blank. If i hold the s button down on the monitor the screen will come back on briefly. I have this same problem. I'm wondering how muchit may cost to repair...or whether best to just buy a new monitor?
Device : Spectra X20WG-Naga
Problem : monitor comes on then flickers then goes off
solution: Replace Capacitor C101 (150uf, 35V) and Fets U101 and U102 (4511GM)
Comments: This is a common problem with this monitor.

I'm about to do the exact same thing. I think the issue is with the main power board's capacitors. Unfortunately there's no good description as to which caps are responsible for the backlight and which ones are for the TFT's.
I'm assuming the larger 2x 68uf @ 450V and the 2x220uF @ 25V have to be replaced so I'm waiting for those parts now.
If that doesn't work, I'll swap out the 8x470uf @ 25V next.

It's seems your backlight inverter is busted. To repaired by yourself, it cost about $10 in parts. Assuming the proper tools. To buy a new inverter from Screptre it cost about $70. Take your picks...Good lucks!
