Hi. Got a Mits CS-35505. No Vertical. Changed vert output chip, no effect.
Followed input back to stand-off board connector CE pin 2, then on back to
chip AN5306NFBS. Scoping, on startup, looks like vertical pulses for just a
second, then goes flat.

Set runs with flat line, which is where all this started. Good voltage to
vert out chip, but no input. Seems to originate at the 5306 chip but I
haven't a pinout. Looks like good 5 volts and such into 5306 chip, but
vertical pulse dies quickly.

Thanks, Danny
