Bright spots in LCD

[dewdude82]

Hi,

I recently acquired a 19" Dell flat-panel monitor that came with a now-dead XPS 400 after being in a house fire. While the desktop died, the LCD survived just fine...a little dirty..but there are no dead/defective pixels that I've found...it does however have an issue.

Down around the bottom..there's some bright splotches in one of the reflective/diffusive layers of the panel. The pixels in front of them work just fine becuase if you drag a photo in that area you can see everything..it's just washed out.

I know they can sometimes get crud behind them that would cause dark spots (my old laptop had that and about 30% of the sub-pixels stuck),but what would cause bright spots? Do I need pull the panel apart and attempt to clean it or should I just live with it. I let the panel run all night and they seem to have faded quite a bit.

Seams like it may be a bit of smoke damage.

Or heat damage. Was the bezel around that area of the monitor warped or otherwise not the same as the rest of the bezel? could be a pressure point that's causing the distortion.

I just looked a little while ago and they've faded a WHOLE lot compared to yesterday. The panel didn't show any signs of heat damage. The basement only mostly got flooded, i'm not sure about the smoke...it didn't show any signs of that either, mostly that it'd just been wet. After I cleaned it up with some Windex the thing looked like you just plucked it off someone's desk.

The tower is a different story..I can't get the mobo to boot and I'm leaning more toward the front contol panel has some kind of issue; I read that if the front USB ports get damaged on these dells the system won't boot. I'm trying to find out how the thing works so i can attempt to trigger a boot.

If that's the case, couldn't you disconnect the front panel?

might just be a backlight bleed, lots of crappy monitors have bad backlight bleeding. Acer G24 anyone?

edit: nvm I saw the pictures. I have no idea.
