Touchscreen dead except when I....

[jackelmatador]

So hopefully someone is able to help me out. My touchscreen on y TP2 is sort of dead. The reason I say sort of is because I can get it to work under two conditions. The first one is if I take it into direct sunlight and point the screen straight at the sun then start touching the screen it comes alive. The second way is when I press somewhat firmly on the top part of the phone, by the speaker I think it is the proximity sensor. If I squeeze right there with my thumb and my index finger on the back, I can usually get something working. I think the issue my be with my proximity sensor. I tried several different roms include booting into android, and all experience the same problem. Anyone out there able to fix this without replacing the hardware?
