Video Polarity and Direct Injection

[vts1134]

It was the power supply. Using a 12v battery eliminated the vertical bars. I have two other video problems that will need to be addressed, but I need to ascertain whether the problems come from the inverter, or are inherent to the set. I'll report back after some experimentation.

I've had precious little time to spend at my bench, but I did manage to sneak this 10 second video in on where I am. There is some crazy interference happening right now that I wanted to show you guys. I hope some one has seen this before and can point me in a direction. I am using shielded video cable (I thought that might be the issue). Any one ever seen something like this? https://youtu.be/zgcznUOokvw

P.S. I will try to get some time today to fire up the B&K 1077 and see if the issue persists when using it to inject video instead of the video circuit we made.

I'm continuing this topic in a thread about the restoration of the television in which I will be using this amplifier. Here's a link to that thread http://videokarma.org/showthread.php?t=268361
