[TechAssist] Zenith A60M91W1 with 9-1978 module no pix after 10 minutes

This set will run for 10-15 minutes and then the picture goes out. Set
looses high voltage but still has sound. I removed the 9-1978 which was
replaced about a year ago. I soldered all the normal places that go bad and
really never found any problems. If I let it sit for about 10 minutes
unplugged then plug it back in it will run again for about 10-15 minutes
again. I tapped around on the 9-1978 and the set never changes. The HV block
measures 50K and the convergence module shows no sign of problems. Any idea
from anyone out there?
