I am still bewildered by the Pincushion issue, but I found an area of the circuit that seems to be a little amiss.
There's some readings that are what I would call "shaky," or that they bounce up and down a bit on the scope and are hard to lock in with the trigger.
Also there are some areas that the voltages are a little bit off; nothing is extremely off, but there are some spots that look about 1V or so off.
The "worst" of these spots is around Q312, which is supposed to be 9V on the collector, but it's a little above 10V and bounces around up and down. The base is supposed to be 3.9V, but it's 3.3, and the emitter is supposed to be 3.2V and it's 2.7V.
Normally, this wouldn't look like a smoking gun to me (and it doesn't really), but I'm not seeing anything else much wrong still, and it's right in the "Side Pin" circuit, which is a prime area that looks to be malfunctioning.
I'm sure I am measuring the circuit with the correct conditions (31kHz, color bars), and everything else on the DA board is almost dead-nuts under these conditions, so I believe I have it right.
So I ordered up some 2SC1632's and I'll start off by replacing Q312 and see if that helps. If it does nothing, I can try Q311, 314, and 315 as the are all in the same circuit and all have a tiny bit of voltage variation from the SM, but none of them are more than Q312 is.
This is my readings. Green is dead-nuts, Yellow is slightly off in some way. The yellow circled resistor values are all in circuit, so I expect them to be off. Of course, if any of those looks weird, then please let me know. Sorry it's so messy, but that's how I've been keeping track of things.
