This set has no PIP.  I went over the major IC's and tuner with a
magnifying glass and found no cold solders.  Sounds like I will have to
go over the entire IF circuit with the old magnifying glass.

2 things might be the problem. PIP and  IF circuits. Also a good check
of 
the whole TV for bad solder would be healthy.
