Just started this tonight. I'm sure the answer is simple but I have no clue. Can anyone tell me what's causing this?

Here's the schematic:

The HOT is Q503. The rectifier is BD001...
Should be diode on both...
Power supply checks out, and I'm getting 115 at the connector. I dont think its a flyback issue either, just looks like a little dirt underneath. I did notice a shutdown pot near the flyback with glue on it. I'm wondering if this needs adjustment. Keep in mind I just had the tube rejuvinated last month and it worked great until now.
I'm ready to pull the chassis and poke at it with a multimeter. Anything in particular I should check?
when i said power supply, I don't mean the games power supply, it would be the monitors power supply. You need to isolate the problem to either a Power issue or a Horizontal issue. Unless you hooked up a load to test the B+ power, you won't know what area to try to repair. Do you know how to test a transistor?
