bad power cord
bad video cable.
bad LCD
bad PC, bad Video card in PC or some game using an illegal video card mode.
try another PC and see if the LCD works there.
easy huh?

this sounds like the lcd inverter inside the monitor is going bad. You can take it in to a repair shop and see if they can fix it but with the labor and parts it might be cheaper to go out and buy a new monitor for cheap especially since black friday is coming up you should be able to get a great deal on one. And it will have a warranty.

Best of luck..

Probably a hardware issue. Cheaper to buy new one than fix it.

I went into the BIOS (with F2 during restart) and changed a value -- IIRC it was called something like "power management scheme" -- from the default S3 to the other choice, S1. Now the old Dell XP Dimension 2350 will go into and out of Standby correctly and the new SE198WFP 19" LCD will too.

kathleen2002, If no picture, then do flashlight test! Six words and no punctuation will not garner much help on fixya here darlin. Tell us more. We need to know how old the unit is and or number of hours use. Did unit work perfectly the day before? Does this monitor get power from a "black lay on floor brick" or does it power up direct from wall outlet? When it worked last, did it have a bright, crisp image displayed on the LCD panel? If you are not a technician familiar with LC display technology you will NOT be able to repair it. As a consumer/user, your options are very limited. 1. NEC warranty if covered. 2. Cash+old monitor swapout with NEC for a refurbished 1550V w/new CCFT/inverter/SMPS. 3. Local Technician to refurbish your unit with new cold-cathode-fluorescent-tubes+Inverter supply repair if required and test unit's switch-mode-power-supply. 4. OR just trade up to a new and younger model. Bye for now. louie12fix on fixya or lmistyrel @aol.com

manipulate each ac power cord wiggle it . PS died?

Hi ,
The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.

You have to install the nec driver for this monitor. I have the same monitor. Im looking for the driver now. There are 2 versions of this monitor with the same model # . You will need to find the driver to the touchscreen model.

The power supply section may be failed, or there may be a short on one of the boards causing the monitor to cycle through the protect mode.

You can TRY to look for cold solder at the board esp popwer section.
