RCA hd52w67 Convergence won't complete (by 3 users)

OK I had a focus problem with the POS TV about a year ago. When the TV got back from the shop the auto convergence would start but would not finish. I called the repair shop he told me to disconnect everything unplug the TV and wait a few hours and then plug the tv and run Auto Convergence before I hooked up cable video games etc... This seemed to work fine. I never paid it much attention after that because the TV stayed converged. I moved the TV last weekend ever since the convergence is out of whack and of course the convergence process won't complete. What can this be? Is there a way to do a hard reset on this TV. RCA aint what they used to be. Thanks in advance
