APHawkes-I see we were posting at the exact same time. It looks like we said basically the same thing, except I think I will take your advice and use the heat shrink tubing. (I originally cheesed out with electrical tape.)

First, make sure that the power supply is your problem. Open up the CV and use a multimeter to test the voltages coming in from the power supply both with the switch in the off position, and then in the on position. The pin outs are ground, +12v, -5v, and +5v. If you are getting the correct readings ...

Thank you everyone. The computer power supply worked like a charm! I am going to connect the end of the cable that was with the original power supply so I can leave the console itself in tact. I just have to think of a way to improve the look of that big AT supply (or just hide it from view ...

Thanks APHawkes for the advice. One quick questions before I fire it up. Does the current output matter? The PC power supply will be putting out significantly more amps than the Colecovision.

Thanks for helping an electronics novice.

I hadn't thought of a computer power supply. I will give that a shot. Also, I appreciate everyone's concern and will be sure to leave all power supplies unplugged while working on them.

If I were to buy another power supply, I don't think I would have a problem anymore. :)

Seriously, though, I have read that Colecovisions are well known to have problems with their power supplies. I was hoping someone here has had experience repairing them and could point me to a common issue (i.e ...

I recently picked up a Colecovision for my collection at a local garage sale. Unfortunately, I only get black screen; no sound or video. After some testing I see that my power supply is putting out the correct voltages (+5, -5, +12) UNTIL I flip the switch on at which point the +5 drops to .8 with ...
