I need to replace only the Touch Screen on my Prophet.

I have bought a replacement Touch Screen and opened my case fully to reveal TFT/Tocuch Screen part.

I was disappointed to note that I will need to do some soldering, but worse, I noticed that the TFT and Touch Screen were stuck together. What do I do? Is is a case of being forceful and pulling it apart?!


Would be great if anyone could give me some support!
:(

Thank you,
NP

Did you solve This? I have the same problem. I bought a LCD replacement and anfter dissasenmbly i realize that this part was in perfect shape. The problem is a very thin film that feels like platic at the top. I take out that film and try to sepparate the LCD
and it was scarry...
This is what i bought: http://cgi.ebay.com/...em=290226792247
I also realize as you that I have to do some solderind so I went back and reassembly my prophet.

2 questions: is there any site that explains how LCD Touchscreens works?
Is there any dissasembly site, pictures or movie with details?

I foun very easy to dissasembly this device but the LCD scrren is not workong afer reassembly. Something is wrong and I don´t know what it is.

Please give me some help.

Same problem I had. I bought the "touch screen" only and there is a soldering (not easy at all) of a flex with 4 terminals to be done. I try to solder it but it wasimpossible (amateur) .So i forget about it and I order anothe COMPLETE LCD (45U$ at e-bay) and problem solved. 45U$ vs 9 U$....
