After fixing my desktop by replacing a new fan, here comes a new problem on my PDA unit.
White screen of death...one of the most feared disaster for PDA owners. Especially the ones who drop their units.
I dropped mine. And how fragile it is...it gave me a white screen. I bought a T5 screw to open it up. Thinking that I could easily fix it since I had successfully fixed the LCD panel on my digital camera a while back.
Interestingly enough, that time, it was the problem with the backlight on my camera. Now it's the problem with the LCD, I think.
After researching around the web, the more satisfying site I came across was the one relating this problem to bad connectors (due to oxidation) and could be fixed by scraping off the rust. However, this is for much larger panel (Laptop size in general). My HX2755 is quite small and therefore although I saw what seems to be some sort of rusting (all but one are gold leads), I could hardly scratch whatever dark silver thing might be on it. It could even have caused by gold paint wearing off.
And then I came across the pages on LCDs. After learning some facts about LCDs, I have concluded that if my problem is not the one above, then it could be even worse: when I dropped it, the liquid crystals were wasted through some possibly tiny cracks. Hence, the white screen (only backlight through the screen). If such is the case, the only way to fix this unit is to get a new LCD panel of the same type...which is quite difficult.
If it is not the cracks, then it could be the handling of voltage/circuit has been corrupted, causing the crystals to be frozen somehow.
I thought technologies nowadays have made things more resilient and lasting. If it is really this fragile, then I might consider not borrowing to anyone blindly, especially those who might drop it, unless I'm fully loaded.
This unit may become my future experiment.

I have also learned some lesson in time management here. As it tackles my obsessive habit.
