Attempting first project - Some questions if I may

[albanks]

Thanks everyone for the help. Well, guys I don't know what to say. I tried everything. I was most excited about the cold solder joint theory as my soldering is sloppy and it made the most sense. It almost paid off, but then it didn't. I might just put this set on the backburner until I can meet some people who can help me in real life. For now, the '65 is more promising to work on.

Nothing to do with the world shut down, resurrecting old thread.

1971 Zenith B/W 19inch - I recapped it as my first project and it was working flawlessly for hours on end. Later on, the on/off/volume switch became loose and the 'stick' which inserted into the switch fell out. I glued it back in but ever since then the set doesn't work for some unknown reason. I have no idea if that is related to my problem or a coincidence. The fact that I turn the switch on and the tubes light up, does this mean the on/off switch is not the problem?

Where I'm at this morning - I opened it back up. Plugging it in and turning it on lights up the tubes but I get no sound or picture. It seems like electricity or voltage isn't even running through the thing. Not sure where to start.

I know some people get annoyed with beginners and some people like helping beginners, but yeah, I need help! I gotta get this thing going again! I'm gonna go bust out my old repair books and search this forum but if anyone is feeling charitable and wants to help please let me know.

Thanks!

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.
