Monitor takes forever to "wake up" once its on everything works perfectly. Is there a reset?

Sounds like you may have a bad connector. Make sure it fits snugly in the pc and the back of the monitor. If you still get no input try a different connector

what happens when you power on?

As your monitor had showed up once before, I assume it is still in a good condition. The next time, you were not able to wake up the monitor by pressing the power button on your CPU cabinet, which means, the power supply to the monitor may have been interrupted. To check whether your monitor is working properly, plug it to any direct connection and see if the power button on the monitor is flashing. If this works, get everything plugged up, check all the connections properly and try to run the computer again.

Hope this helps, Mrityunjay.

Change all the suspect caps or better still use a cap tester to check out their ratings. Change those that are out of line.

slapping it around usually works. "just a joke!"

tapping a few keys on your keyboard and moving the mouse will usually wake the monitor from sleep mode.

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.

Maybe you can update your video card driver. My wife notebook is connected at times to my DELL17" flat screen and ever so often it cuts off in the middle of something. I update the video driver and reset the monitor to factory settings and it's working like a dream.
I suggest, you use the menu buttons on the LCD and reset it ot factory settings, and possibly update your video card.

I bought a new monitor. Problem solved.

replace 2 caps 1000uf each 16 volt
I purchased 5 of these babies (new) at the same time and 3 of them had this problem

It's sort of a solution, but I work in a computer shop and got this screen in yesterday. I looked at it closely and it's actually the backlight that died. I pulled it apart and found that three of the 820uF/20V capacitors had swollen up. If you replace them then you should be fine, but I went for a different approach and took the inverter board from a laptop and put the in the screen and used an external power supply. It's a bit dark but it works fine now.
