Question about Sceptre X5G-Komodo IV 15" Flat Panel LCD Monitor
My Sceptre Xg5 Komodo just stays on for a second or two and then goes black.......Displays accurately for that amount of time. Cut it off and back on......Same thing. LED indicator is on when it goes out. Any Ideas?? Thanks to all who take the time to answer.

This trouble maybe power supply or inverter boards is defective.
first you can test the voltage of the multr,and then check which part is defective.From Wisiny.com can find those parts
if you have any question,please let us know email:firstname.lastname@example.org,we sincerely hope we can help you!

Look for bulging ends on can shaped capacitors. The most common one is 470 Uf. I replace them with a slightly higher voltage rating, like 35V instead of 25V. The new ones are only slightly larger, and fit quite well. This solved my problem on about six of these monitors I have had go bad. Right now, It seems that someone in the factory put 1200 uf capacitors in two of the four spots. I am in the process of replacing all of them with new 470 uf capacitors. The repair kits you buy online do not use higher voltage rating capacitors, but I have been doing it and never had another one go bad.

Well, that was easy.
Inside my Sceptre 19" X9G-Komodo II I found two bulging 25v 470uF electrolytic capacitors on the power board.
I didn't have any new 25v electrolytics, and I was in a hurry, so I scrounged around in my scrap heap, and found an old 9600 bps modem with a pair of 25v 470uF electrolytic capacitors in it, and replaced the bad ones in the monitor with the ones from the old modem. The monitor is working fine, now.
So, if you find any bulging capacitors, replace them. Also, replace any others of the same type & size (they are often in pairs), since sometimes they go bad without bulging, and if one capacitor of a particular size & type is bad then both of them probably are.
(If you don't know what I mean by "bulging capacitors," google for "badcaps.")

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
