Could you please help me to resolve this problem? Thanks the screen stopped displaying. If I press the button OFF and ON again,the monitor will display information for about 1 second and after that the screen is blanked/blacked out even the power is still ON (green).

SOURCE: Sceptre X9G Komodo IV

I have a 19" Sceptre Comodo display. After 3 years it got the problem everybody complains about. Took it apart yesterday.

There are 4 capacitors in a row on the power supply board (it has a socket for the power cord and is covered by a metal shield. The caps are barrel-like things standing upright on the side opposite to the power cord socket.) Two of them are 470 uFx 25 V, they are next to each other. In my case, one of them popped up and another one was bloated. I pulled out the power supply board (make sure you unplug the power cord and press the power button do discharge the high voltage caps before messing with your monitor) after disconnecting all sockets (mark'em!). I assume that you have new caps handy (I paid $2.10 for a pair at a local electronics store), they must have the same capacity and voltage rating. Now grab a soldering iron, remove old caps, and put new ones in. You must observe polarity! (Usually "minus" pin is labeled on the cap's side. Mark down "minus" and "plus" pins location of old caps and put the new caps in exactly the same way! Otherwise, you can blow the caps.) If you are not used to work with a soldering iron, hire somebody or buy a new monitor. Check the quality of the work (no shorts, solid contacts, etc), assemble the monitor back and may be it will work (did for me). If it does, you put one monitor less into the city dumpster, be proud to get a working monitor for less than $5, and force you mother-in-law to take this shiny new replacement display she just bought back to the store.

Of course I do not guarantee that my procedure will work for and you can use it at your own risk only (i.e. I am not liable for any damages).

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

To me it sounds like the bulb is having a problem with powering up. It may be an issue with the power adaptor or the outlet it is plugged into. Have you tried to plug it in, in other outlets?

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.

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.
