Question about Sceptre X9G Komodo IV 19" Flat Panel LCD Monitor

Sceptre X9G-Komodo IV

This monitor is identical to the planar pe191m. "anyone care" posted he/she had repaired 15 of these with 2 bad caps in the power supply. I have 4 of these monitors and was wondering if "anyone care" or any one else could suggest which caps normally cause this problem?

    The monitor simply flashes the power on indicator and goes of. It ***** comes on again except you pull out the power cord and put it back. I was able to observe a twiching sound on the power board indicating inability to of a gate closing after a current flow. It is absolutely difficult to get components her i Georgia. My guess is far from one of the transitorized diodes or the only 4 leg IC "U103" on board. If I can find these two components, I will be fine with the fixing.

I recently came accross one of these monitors (Planar PE191M) with the identical issue. The resolution was to replace the two 470ufd 25V capacitors that are located on the main power board. The main power board also contains the audio circuit and more importantly the inverter circuit that drives the CCFL backlighting. The suspect caps were identified using an ESR meter; if you happen to have one of these meters you can confirm this is the issue with your unit(s), alternatively you can just replace the two capacitors and see if it resolves your issue. Hope this info helps someone out there.

It may have dying power supply due to bad DC filter caps like the 17" version.

If you are going to DIY and already try the monitor with another PC, 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/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

This board is out of my Sceptre X9G Komodo. The 740uf capacitors are clearly marked 25V. The 1200uf Caps are 10V. I ordered parts for mine to try. The darker 740 has a slightly "popped" top.
470 is about 10mm dia X 16-17mm long
1200 is about 10mm dia X 20? long
two leads on each about 5mm apart. They are soldered to the board.

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

X9g komodo v screen just turned blank (white)


Go to ebay, type X9g kimidi logic board. Usually, some seller might have pulled working parts from other monitors and sell them individually. If you cannot find them, google "buy x9g komodo logic board". Some website, I'm quite sure will sell them.

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.
