Damaged digitiser?

Hi folks. I have damaged my topaz but I'm not sure if it's the digitiser or the lcd screen, so I'll describe what happens:
The touch screen will stop responding after I've been using it and if I turn off the screen I can see a small dark patch (where my finger last touched it) with some small tiny 'bumps' surrounding this dark area. If I gently rub the screen with a soft cloth or similar, this dark area disappears and the touch screen starts responding again. However, I am having to do this procedure a lot - I mean like every 10 or 20 seconds if I'm touching the screen a lot or dragging stuff around - heck, it's a 'touch' phone, I can't help but touch it !!!
A new screen is a lot more than a new digitiser, and I figured that since the digitiser sits on top (right ) then it may be this that is u/s ?
Any help, comments or diagnostic clues are much appreciated.
Cheers, peace
Chris

umm, can it be water between the screen and touch sensor layer? Have you brought the phone to highly humid places, or something like that?
Some photos will definitely help identifying the problem.

Sounds like this:

I had it, and my provider repaired it. Unfortunaly I have the problems again... but not that much. When its getting too extreme, I'll send it back once again

^ I'd say that's it, I did find another post with a photo of something similar too.
I think mine happened when my wee girl got a hold of the phone -
I'm still a little unsure as to what component is damaged tho. Maybe a little 'investigation' with a screwdriver is needed ...
Thanks for the replies so far
Peace

Using a screewdriver will defenetly kill your guarantee. Mine was repaired for 0€$ ... I would try this first, as you can still offer it back when they say u have to pay few 100€$.

my touch shows only white screen

hay from today morning my htc touch shows a white screen and a crack on the bottom corner of the screen.i am sure that it dint fell down.
then what may be the problem?
anyone knows pls tell me...

white screen?
When you turn on your phone, there is no smart mobility.
Crack?
Is that an LCD problem?

i have the same problem with the WHITE SCREEN. bought my ELF 3450 second hand over the net. i am from the Philippines by the way and HTC units are not yet very common here and also the parts/accessories. it worked fine for about 3 months with minor problems such as Auto-Restart/Auto Power On/OFf which was solved using the "plastic on the OMAP chip method" - tnx for the forum for the info by the way and charging problems which was also solved by buying me a aftermarket charger. but recently the problem of AUTO OFF occurred again until it did not work at all. so, i tried to check the Plastic over my chip but to no avail the fone was dead. so, i decided to head to one of our local cellphone repair shops and have my OMAP heated thinking that maybe there are just contact points inside who became loose. when we tried to power on it was good for a few minutes then i noticed the screen went darker and darker and then it was all WHITE. we restarted it but it's just WHITE. tried to send messages and call it but there is no response from the fone. i'm afraid i toast it bad or may be it's just the LCD who got toasted, i am clueless.
CAN SOMEBODY PLEASE HELP ME WITHMY PROBLEM. CAN I GIVE LIFE BACK TO MY ELF? WHAT'S THE CHEAPEST & BEST SOLUTION TO THIS? THANX ...

Generally white screen problem are caused by defects in flex connecting the LCD to the mainboard or the connector itself. Try to disconnect and reconnect the LCD, if doesn't work - replace the LCD.

You warmed the OMAP? Interesting....

This problem sounds really complicated.
And im quite surprised of your 'warming' method.

I've had the exact same problem combined with the fact that my touch was resetting constantly. I was about a minute away from throwing it out of the window when I tried the plastic-piece-on-omap processor-technique described in one of the threads here. It solved the rebooting problem, but not the white screen issue. After a very frustrating couple of days where the screen started to blink and shake and then eventually turned to white alltogether, I lowered my brightness to the second stop from start, and since then I haven't experienced the white screen anymore. I believe it is heatrelated.
Whilst not being a full solution to the problem, at least it renders the phone usable.
Hope this helps anyone.

Heating the device very seldomly solves anything, but causes more problems that you originally started with.

iam using htc touch (p 3450) for nearly 18 months . (bought & using it in india ) my hand set fell two times in water and about 15 times fell on the floor (from shirt pocket) . still its working fine .
and iam using "opera mini " for browsing the internet . for some sites iam using "opera mobile " . when iam on opera mini , continueously for long ours , suddenly it turns white . never come to normal screen unless restarted . but it happens sometimes , may be because of memory or heating up of some H/W .

Hi hotchamo,
my htc touch elf hat a similary issue, and my father just "wringed" it gently until the white screen disappeared. You should try it carefully, since it may help and it won't harm. Just take in in both hands and turn them in the opposite direction, so that the case gets slightly twisted.
If that doesn't help you should open it and check the LCD flat cable connector...
Best regards,
scheutak

Again - flex connector problem. 'Wringing' it gently will eventually result in your LCD cracking, by all means - go for it, it will solve your white screen problem. Permanently.

I had same problem. For me there was a piece of dirt between the screen and the cover which was causing the screen to be pressed. I removed the cover and cleaned the dirt from around the frame and the screen is now working. Hope this helps

i didn't drop my gene......... and how could i clean the digitizer of it?
