Coleco Telstar Arcade Help

Recommended Posts

Hello everyone,

 

Hoping someone with experience with the Coleco Telstar Arcade can help out. I purchased this and plugged it in. Started off with black and white color, tv noise, jittery paddles, and internal speaker hum. I dont have any experience with these. I adjusted the rf modulator fine tune coil and got the color and picture working fine, but still trying to figure out the tv static noise and the internal speaker hum. Is the speaker hum normal? Also, any ideas as to how to get the audio working on the tv without the static? I turn it on and its static free for about 3 seconds, then it starts. Anyone ever repair one of these things? Anywhere I can find schematics?

 

Thanks everyone. post-61342-0-65644400-1535719679_thumb.jpeg

Someone did an AV mod on one of these. That might help fix a lot of audio/visual issues if its something you want anyway.

Thanks for the info. Sounds like it will and there is plenty of room inside the box for the wiring and jacks. Happen to have a link to the thread by chance? Thanks.

I can't seem to easily find it. Probably something I stumbled across. The guy in this post said he was going to do one about a year ago, so you might contact him. It sounds like an interesting project. If I can find one at a good price I'll probably try it myself just for fun.

Is it the pot on the rf modulator or a different pot? The inside is still wrapped in foil at this point. :) I will take it off if the pot is underneath, and will likely have to anyway to check for cold solder joints, etc.

What kind of TV are you trying this on ? if a newer flat panel try and analogue channel search while console is on ( probably still have to tune the RF pot.
