I would appreciate step by step guidance. Thanks so much

    Thanks troylove11, I appreciate your help. After opening up my monitor I noticed on the power supply side a capacitor that is slightly bulging, however the number on the capacitor was EJ(M)105(degree symbol)C (c)0424. A guy at Radio Shack said it wasn't a capacitor with those numbers on it. It looks like one so does anyone know what it is? Thanks for any help.

    use an old driver's license and slide it around the monitor case where it comes apart. There are clips inside that you will hear unclick once you do it.

This has been very helpful but I'm stuck. The board where the power supply connects is a large one. It has (if I'm identifying them correctly) about 20 caps on it. Some canister-shaped, others blue dots, and one that looks like an orange-red chiclet. None look to be bulging. Any suggestions as to how to proceed would be very helpful. (I am trying to repair a monitor which for some time went black for short periods of time and now is always black but power light is on.) Thanks in advance, Amy

First open monitor (with power off) find power supply, this is the part where the AC cord plugs into. Inside back of monitor you will see a small board with components on it. You should see a big capacitor. It should be round with 2 leggs sticking out going on the board most of them are layed down, sort of bent over. this is probably the ac filter cap for your monitor, it should have something like a number with UF behind it and at 100v or 160v or depending on monitor. Sometype of voltage this is what you need to change and look for some other out of place cap. Beset is to change all large ones. You can find caps at www.bluestar-online.com. These are electrolytic caps. There are many different kinds. Hope this helps!

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?


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.

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

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!

Where to find capacitor


www.bluestar-online.com, mcmelectronics, tritronics etc. You will need to heat up the soldering trace, or legs of capacitor and pullout gently.

Sceptre X9G-Komodo IV


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.
