On this RCA P56720 with a CTC169PM chassis what I thought was intermittent video turned out to be blanking from channel to channel even with control cords off of chassis the channels still change. Has anyone experienced this symptom at all. I changed the system control chip and found no solder splashes from original repair. Any tips would be appreciated. Thanks in advance!!!
