Interesting, the first picture almost looks like you have all the Color information but none of the Luminance, i.e. Color but no B&W picture under it.

The second is a collapsed Vertical Sweep, either the Vertical module didn't get put back in correctly or you bumped the Service Switch which will put it in a flat line, turn down the brightness or you risk burning a permanent line in the screen!

Could be something as simple as a bad video module. I will need to find my service manual. I think loss of video will cause loss of clock and channel display.

I dont think you need a horizontal module, either. Your HV is running and the picture is there.

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.
