RCA P46733AT Chassis PTK178LA Plays for hours then shuts down. Customer said TV popped then shut down. Only thing we found wrong was the focus block cracked and bad. Solder all look good on main board. Not much in the techassist on the PTK178. Any one have anything on this one to guide us in the right direction?
