My Predicta crapped out

[madlabs]

Howdy All,

Well, tragedy struck last night. We were watching "What's My Line" on the Predicta Holiday and the picture was a little unstable. No adjustment helped. It was just jiggling, it didn't seem to be the horizontal lock. I have noticed a little occasional jiggle over the last few months, now that I think about it. The jiggling got worse and then *poof* we lost picture. I can't say if we lost sound because we have been running the sound through the stereo and I was on my feet and hitting the power off as fast as I could. This morning I tried turning it on. It has a picture, disturbed as it was last night. I am guessing if I left it on it would go dark again. Sounds like something is getting warm. The set smells fine, no hot smell.

Some background: I "restored" this set, finishing about 4.5 years ago. "restored" is in quotes since it was my first and only TV that I have worked on. "Got it working with the help of this forum" might be a better description. It has been recapped, new tube sockets installed on the PCB, new couplates, new diodes, replaced the fusible resistor. It has been working fine for years with hundreds of hours on it. I am hoping for some help with troubleshooting, I am not an expert and my theory is weak.

Many thanks in advance!
