Sceptre Monitor P/N X7G-Komodo II displays for about 1 second at a time, then goes black. When I cycle monitor power, I see a perfect display for 1 second. Does anyone have a recommended solution?

    bdaqq, retrevo .com lists unit as time to retire. Other solution is valid only if you are familiar with use of soldering pencil / soldering iron, solder wick, solder. if that not option for you, then trade in for new wide screen 2010 model. If reading of FIXYA PROFILES of "bunmrtn" "buddymc" "12fixlouie" for repair information on quick, cheap, DIY repair, still not your cup of tea, then hurry down to the closest big box electronics store and get new wide screen ccfl wide screen lcd monitor. Have you been to YOUTUBE to see just what you might need to repair your lcd display? 12fixlouie

When the backlight does not stay on for more than a second, the problem is usually the backlight power supply board failure. Typical failures are blown capacitors, or transistors. A electronic repair shop should be able to fix it.

Look for bad caps as shown in my pictures here first: http://s807.photobucket.com/albums/yy352/budm/Sceptre%20X7G/

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

I have a Sceptre X7G Komodo II 17" LCD monitor/built-in speakers


You would need to connect the speakers to your computer. There should be a little jack on the back of the monitor marked audio. This will need to be connected to your soundcard jack for front speakers. Once this cable is connected you should have sound from your speakers. Hope this helps.

Same Flashing Problem


My Sceptre Komodo 19 would turn on for less than a second than turn off. Eventually, I could get it to stay up. But after a month, I couldn't get it to stay on anymore.
I found the solution on this website. There are some bad capacitors... 4 of them for about $2 worth. I replaced all four and the monitor works fine again. They are soldered in. They are polarized; they need to be installed the right way. The white stripe goes towards the “wall”.
2 are 470uf 25v and 2 are 1200uf 10v.
I ordered mine for about $10 with shipping from Mouser.com

Monitor Powers off after a second or two.........


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.
Good Luck!

Hi dgp1952, Check with www.lcdrepair.net if you want a repair. Something is wrong with your backlight or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. Dust can cause the circuitry to heat up faster and put the power supply into Clamp mode. Clamp mode will turn the supply off to certain circuits which may be the reason your display is going black after 5 minutes.
