With bad connections/solder problems out of the way, I agree with bill, see why the tuner indicator is not on, it could be one of your power sources, like a 12v, or something like that. Also the first picture posted looks like color, but no luminance information, like already mentioned. So hopefully there is a open resistor, bad cap, or bad solder connection somewhere in the low voltage power sources. It may not be what most refer to as B+, but one of the lower supply voltages. But again, all the turnie things are not currently the problem.
