DL-1 Hell

What's up. So I have a unit that was displaying a projector com error. I opened the unit and replaced the comm board, but still recieved an error message. Next I replaced the fan board. This took care of the "proj Comm err." When I power up the DL1, however, the unit does not fully home. It goes clockwise and once it hits the stop, attempts to continue to go in that direction. I replaced the pan sensor, thinking it was an easy solution, but am still having problems. On top of that, while the fixture has power, the splash screen locks into an eternal scroll of useless information. :poke:One time I was able to get past the splash screen, only to be thrown into another circle of locking up and going randomly through the different options in the menu. Any suggestions? (or TNT that can be borrowed). Thanks all.
