Oil Slick appearance under fluorescent lighting on the touch pro
 

I just started noticing this problem yesterday. The guy in the original thread noticed it when he was an inpatient in a hospital and I am a doctor and I first noticed this while I was at work yesterday. Interesting the problem isn't apparent under sunlight or regular wattage bulbs, but under fluorescent lights, there's a big oil slick appearing square. This was a problem on the touches as well. Does anyone know the cause of this? It never was clearly answered in the thread below, but the suggestion of a leak in the LCD fluid seems plausible.

It's probably NOT a leak with the LCD screen. It's probably trapped humidity between one of the layers of the screen. it's made like a sandwich. Protective layer, digitizer layer, protective layer, glass sandwich with the LCD goop.

When your backlight (which generates a small amt of heat) warms up the ambient air inside the device, esp for folks who live in northern climates where it's cool out, that slight moisture has to go somewhere. It's usually NOT enough moisture to affect or damage electronics but it does play hell with layered screens and such.

+1 on that. It should evaporate or at least decrease in appearance if you take battery out and leave phone under a hot light bulb. Try at your own risk though.

Um, I wouldn't put it under a hot light bulb. :) Esp NOT too close. the top several layers of the touch screen are rather "soft" plastic, and I surely don't want to speculate on the melting point of it.........

I to am having this issue on my HTC Touch Pro, I have had the phone since 11/5 and this takes up most of my display. My is under all lighting conditions very strange.

I have never tried this, but read it in lots of places. Try putting your phone in with a bag of rice for a several hours. I might draw the liquid right out for you. People do this when phones are wet all the time.

Yeah, I started noticing this problem within having my Touch Pro for a couple days. It's really annoying. Would getting another screen protector and switching the current one help? Or would the problem just come right back?

Sadly, this is normal with most PDAs that I've owned.
