Attempting first project - Some questions if I may

On this set if the tubes are lit but its dead the switch is OK.
Look at the ground posts like mentioned in my prev post.
Also get a long plastic stick & lightly push on things to narrow down the area
the problem is in.
After that you will need a schematic & meter but it should be easy to find.
good luck

Hold the phone. I think I licked it. What happened was this was a case of bad soldering. The problem was that one of the wires came loose. I couldn't see it due to the electrical tape. That's why if you watch the video I posted earlier in the thread it shut on and off as I rocked the set, as the wire was touching and then untouching. Well, I guess I learned a valuable lesson.

It works now but I'm getting extremely loud buzz/hum/interference. Something like that. any tips for that? Buzz control does nothing.

The buzz control is only useful when you have a good signal received.
Please don't use tape, it never lasts and can get messy. Check out heat shrink tubing, it takes a little planning because you have to put it on before you finish soldering.
Recheck you connections.

Thanks, everyone.

When the TV is plugged in alone the snow sound is normal.

When I have the DVD player, RF Modulator and Digital Video Stablizer plugged in it creates the buzzing. I have tried different outlets, unplugging nearby things not needed, nothing. Am I getting some kind of interference by having this setup near my other electronics?

Sucks to get this close and now have such a dumb problem.

Buzz can be a PIA on tube type Zeniths.
Try turning down the AGC control. Its along the back like the buzz control.
If its too high the set will buzz, too low & the pix will wash out.

Next problem is sources. These sets are before any add ons like games,
VCR, DVD, cable boxes etc so often they buzz or get torn up pictures.
Best test is usually a VCR direct to ch 3. The pix will tear at the top
but the buzz will be much less if at all if the TV is normal.

Thanks, Zeno. I hear ya, I'll try that. 2 years ago I had this thing playing Columbo from a DVD player with no buzz. I will try to fiddle again with the AGC and whatnot. The sound I am getting is like a ground loop type thing.
