Look for bad caps with elaking/bulging tops as shown here (it is similar to the X7G which is 17" model).

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.

LCD goes black after few minutes


I would suspect the capacitors on the power supply board. Other sites show that power up problems are due to the aluminum electrolytic capacitors on the power supply board being defective. Replacing the four 470uf 25v capacitors (470 micro farad, 25 volt) on the board usually fixes the problem. Sometimes also the two 1200uf 25v capacitors could be the culprit. I suggest changing them all. The price is about $7 for the parts online at Mouser electronics plus $7 shipping. I just fixed mine. I bought two 1200uf 35v capacitors, Mouser part number: 647-UPJ1V122MHD6 and four 470uf 25v capacitors Mouser part number: 661-EKY250ELL471MH2 These are slightly larger than the originals but still fit and they were in stock. You will then have to open the unit (relatively easy) remove the power supply board by removing four screws and disconnecting the connectors (Make a note of wire colors and where the connectors came from before removing). Then you will need to remove the old parts by desoldering them and then solder in the new parts (somewhat easy if you have soldered before)

Same problem here


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

Sceptre monitor


I would suggest looking at the capacitors on the power supply board. I just got one today with 3 blown caps (the tops are swollen) and a couple missing components.
The ones blown on mine are the 220uF @ 25V and 1000uF @ 16V.
