Sharp XM1801 - B+ takes a nose dive after a few minutes
I have a Sharp XM1801 in my RED TENT that has fresh caps, filter caps, HOT, and a new flyback. I have double and triple checked my work. However, I have some odd B+ issues. I don't think it's the B+ pot. But, not positive.
I set the B+ to 108v and the monitor is perfect. Then, after a few minutes, sometimes 10 or 20, the B+ drops to 50v or somewhere similiar and the monitor shuts down. I hear this click click click sound coming from the flyback area when it does this. I see no arcing or other similar stuff. Did I get a bad flyback? What else would cause the B+ to nose dive? I have a second repro flyback I could try. Just getting really sick of taking this monitor apart!!!
Any ideas?
