Before I cry Uncle and throw a tarp over this TV, I scoped the input of the first video amp to see what is getting through the video IF section.
My pattern generator is set to color bars, which the TV displays as gray bars.
The top scope trace is the TV's video IF output. The bottom trace is direct from my pattern generator.
The signal looks pretty scrawny by the time it gets through the video IF chain; the burst signal is basically missing in action. Tell me if I'm wrong, but I'm taking this as a sign that the TV really does need realignment.
