B&K 1077B "Vintage TV" Questions

OK don't beat me up for this! The thread probably belongs in the "Diagnostic Equipment" category but the issue with my 1077 has to do with the picture I get on the CRT. It's supposed to be an ultraviolet color but on first power up and after recapping, cleaning and messing with the vertical controls, there is no change and the screen looks like the mess in the picture.

Someone has been in here because a number of resistors have been changed including 2 that are listed at 1 meg in the schematic (R-52 and R-53) replaced with much lower value resistors...in the 47 kohm range.

I have a lot of troubleshooting to do but I can use some advice on where to start. I think this is a vertical issue correct? Has anyone else had this problem? From what I've been able to see, most of these work straight away and only need some caps and adjustments. I guess I'm just so lucky eh?

Thanks
