Yup.....for the first time, I'm asking for help instead of giving it. Hopefully someone has some experience with this.

I have a 17" Dell E171FP flat panel (picked it up from work REAL cheap). Turned it off the other day, then turned it back on in the morning. All I get is a white screen. No self test, no OSD....nothing. The white screen is only displayed when there is supposed to be an image on the screen.

unplug VGA cable, screen goes to sleep. Hit the OSD button, screen goes white. Plug it back into the PC, and the screen will be white when there is suposed to be an image. During XP boot, right after the XP loading screen when the PC switches resolution to your desktop resolution, the screen is black for a split second (which is normal) then goes back to white when it should be the logon screen.

I pulled the thing apart hoping to find a dry sodler joint on the VGA 15-pin, but found nothing. I dont beleive it to be the inverter board, because there is a signal to the LCD. The PSU is OK as well. So what I am thinking is its the VGA board that went bad.

Anyone have any experience with this??? I dont want to just start throwing parts at it (the inverter board is about $50...cant find a VGA board for it yet), so any guidance is appreciated.

Thanks in advance.

You did check to see if it was definitely the monitor and not the video card, didn't you?

If it looks okay with another monitor, then I would guess that it is up to you whether or not you try to fix that used monitor. If the parts aren't that much, and you know what you are doing, I would think about going for it.

Even without the VGA cable hooked up, it immediately goes to white screen when it should be displaying the self test. When the self test is done, the monitor goes to "sleep". When the OSD button is pressed, the screen goes white again. Its only white when it is supposed to be showing something. Again, this all happens with the VGA cable disconnected.

Vid card is good (already tested with another monitor, LCD tested on a nother machine with a different cable, etc. Basic level 1 troubleshooting already done).
