Hi allseer,
I also have (little) problems with my iPronto TSi6400.
My screen somethings has disturtions and moves 1 or 2 inches to the top, so no input is possible. After pressing somewhere on the left downside of the ipronto, screen corrects and everythings ok again.
I tried to open the remote (unscrewing the 5 torx-screws), but I could not remove anything of that thing.
I opened the front-side (some platic-holders broke - I rearranged with double-sided glueband later :-( ) but no chance to correct the failure.
So, don't open the front-part of that remote !!!

Did you find any solution to open the backside until now ?

Best regards

Higgi
