    I think that they are in the dc side. They are two small blue capacitors next to transformer T1 and fuse F1..
    The power supply model is LM004 Rev:3 12/01/2003

I think they are MOVs in the primary AC side. Can you post the pictures, or send them to me at budmrtn@aol.com. Most MOV are blue in color, ceramic cap is usually orange/yelllowish color.

I recently acquired a sceptre x9g Naga V monitor which has developed a problem. It produces a wonderful image which may last 5 min or 5 sec, then goes black. If I turn it off or unplug the monitor the...


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.

Not an expert, but from what Ive read, this is a cfl inverter issue. I had the same problem on my Sceptre. Good luck finding parts. My solution: get another monitor.

Check the fuses on YSUS & ZSUS boards, if found the fuse blown on that board, just try to replace the board.

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.
