Sony tv KP-61HS10 lenses wont align


This is common in those sets. One of your convergence IC's has stopped working and needs to be replaced. The convergence IC should be replaced and the convergence circuits realigned by someone with experience in Sony projection sets.

One of the convergence output IC's has stopped working and needs to be replaced. If the IC shorts out then it will draw too much current and possibly blow a fuse, and the set will shut down to protect itself. The IC should be replaced and the set realigned by someone with experience in convergence circuits.
