Replacement touch screen?

Hi all,
my tg01 has a large rainbow patch on the screen, and it is sometimes visable even when the back light is on,

i was wondering if replacing the screen would solve this problem?
and if this is the solution is this the right part i should order?

The part you have linked to is just the Digitiser (incidentaly not apparently identical to the TG01) - the resistive matrix pad which sits over the actual LCD and provides the 'touch' x-y grid information to the processor.

A rainbow patch suggests one of three things:
1. a point of pressure which is distorting the LCD screen under the digitiser
2. possibly a crack in the actual glass
3. inward distortion in the digitiser causing it to press against the LCD glass

I'd look closely first to see if you have anything eg. between the battery and the body which might be causing such pressure forwards; then check the digitiser to see if the surface appears bowed inwards and finally examine closely for any crack.

It may be that a new digitiser would solve; but if there is a crack in the LCD glass then I'm afraid only a replacement screen will solve.

Good luck !

Thanks for your help
i will look into it more
but i think its because of the screen being exposed to a point of pressure because lately i have been keeping it in my trouser pocket along side my ipod which i think has created the rainbow patch
