I have had my TSU3000 for about two years and last week it started losing touch screen alignment. I used the forum to seek answers about the issue. The info about taking the remote apart and cleaning the screen was right on the money. It worked absolutely great ! There was a rather large build up of movie watching debris (coke,crumbs,etc.) all around the edge of the screen. My theory is that this stuff accumulates over time and eventually acts like someone always pressing on the screen causing it to not work correctly. It is fixed and I thank all the members of the forum who posted their solutions to help all of the TSU3000 owners.
