TP2 wont boot!!!!

[630R63]

exact same problem on mine, tried two different sprint factory roms, i see the green HTC logo on one, the touch pro 2 logo on the other, and it resets a bit faster, but ya, they just keep rebooting over and over, i flashed the original SPL back, same deal, and now i cant try other roms, but im guessing that wouldn't help, im just about ready to crack it open and look for blown fuses inside or something. .. been looking thru other forums for this problem too, seems nobody has any suggestions, im prolly gonna crack it open tonight and do an autopsy
