Intellivision not seeing carts

[ddockery]

I have several Intellivision systems, that no matter what I try, don't want to read any carts. I KNOW the carts are fine and really clean, and they work in 4-5 other systems. Is there a good way to get in there and clean these out?

Thanks,
Drew

Open those suckers up and clear out the dead roaches!

From least invasive to most invasive:

1) compressed air into cart slot
2) 50/50 distilled water and ISOPROPANOL :) solution with a new toothbrush, and scrub the slot. No need to have it dripping wet, just moisten the bristles. Then dry well with a thin cloth (not paper towel unless you want to risk leaving bits behind) and a credit card.

If these are Inty 1's, I've seen black screen as a result of an out of spec internal power supply, and due to dead internals, like the logic board. Could be a couple of things. Might as well clean the slot and cross your fingers...

Thanks for the tips. I have about a dozen of these, so I'm hoping at least a few of them are just too dirty. I may open up a working one and use that as a standard to eliminate the power supply possibility.

Thanks,
