Hi,
I had extra time on my hands after I posted (see below) my last message. I removed the PIP module 9 - 1084 and I noticed IC2000 HA11569FS had some corroded pins on three sides of the IC (SMD). In my experience, this is usually the result of a spill or leaky electrolytic capacitor. The way this is mounted, it couldn't have been a spill by the customer, but if it was a leaking electrolytic capacitor/s, I couldn't find any evidence! I noticed that this unit was once serviced (not by me). Could it have been a service tech drinking a soda? I removed the "residue" and cleaned the corroded pins. Now there is color. I ran the TV for over an hour (good color).
