If it looks like convergence
try unplugging all cables from front convergence board to main boards and
reconnecting before replacing any parts.
These 178 and some 169 chassis were bad about tarnished connections on the
pin connectors.
There was a repair kit available.
Symptom: Convergence intermittently collapses, picture bows in on top and
bottom, picture pulsates, black
streaking lines in the picture or TV intermittently shuts down and indicates
error code 78 in the CTC178/188 chassis.
Cause: Oxidation on the connectors going to the convergence generator board
cause intermittent voltage,
signal and data loss.
Cure: Replace the connectors and headers on J/P8201, 8202, 8203, and 8204.
All of these cables and
headers are included in a kit, stock number 212169. Use the included wire
ties in the kit to fasten
the cables to the screw bosses as shown below. This will immobilize the
cables preventing the
oxidation from recurring.
