Radio Shack Full Color TV Scoreboard 60-3055 problem.

The picture is snowy and one of the y shaped metal pieces used to connect to a TV or adapter broke off. I screwed in the broken wire and got the same picture as with the y shaped piece of metal. Tried adjusted rf setting under RF shield no luck. RF cable is soldering on the board.

Well, I've not personally worked on or looked inside one of these, but like anything else with RF there will be a ferrite core within a coil that is used to adjust the signal on the RF output. It could be that has drifted over time and might need to be adjusted or it could be that it is slightly outside the current tuning of you TV. Are you connecting it to a modern flat panel TV or CRT?

 

Oh, and that missing fork on the end of the antenna input wire...don't worry about that. Just twist the wire that is left and wrap it around the screw onto the terminal and screw it down as you stated. Back in the late 70s this is what I did to 'fix' our old Odyssey 300 pong clone. My mother thought it was broken because one of the y prongs had come off and I as a curious child just wrapped the loose wire around the screw terminal and using one of the butter knifes from the kitchen (Which I pretty much ruined as I recall), I was playing Odyssey Raquetball when my mother came back from the store. She was surprised...in shock....without words....and not pleased all at once. I've been breaking stuff and trying to fix it ever since. LOL

Odd design. Looks like the console itself is the RF switch! Never seen that before.

Maybe it needs a new cable? (Not likely but I don't know what else to suggest.)

It is the RF switch. So is the National Semiconductor Adversary ,and the Action Games Color Game pong console. I have been on a pong kick lately.

Here is what the inside looks like. The siler box with the hole on the right adjusts the RF. I don't know what the other two do. I adjusted the RF and can't clear it up.

I can't even close the thing up anymore. Two screw holes are stripped and the screws won't tighten.
