colecovision motherboard NOS ?

[peedenmark7]

My Colecovision has been giving me fits of late. Worked great last time I used it. Turned it on after 3 weeks and now I have a white screen.

 

The screen goes from snow to a white when I turn it on, so I know this is not power related, I also tried a different RF cable.

 

Wondering if there is anybody that sells NOS motherboards like Best does with Atari stuff?

Getting an upgrade for your video out would probably be a lot cheaper than a motherboard replacement. If you have any questions let me know.

Besides ruling out the power switch, I would check and clean the cartridge slot and makes sure the cartridges you use are clean. Does it not work with every game or just some?

have to believe the switch is good as there is a change in the scree when turned on. I will check the unit , but I tried 3 games and my multi cart all with the same result. Tried a different RF cable as well.

My tv has an icon that pops up saying no signal..

What's the best method for cleaning the cart slot?

 

Thanks

I always use a toothbrush and rubbing alcohol and scrub really good. If you have a lot of corrosion though, some fine grade sandpaper wrapped on a used/cut up credit card (or similar) would do the trick. Cut it to the size of a cartridge and insert/remove a number of times. If you try the sandpaper, be sure to follow up with the toothbrush/alcohol in order to remove any leftover residue.

 

Also make sure your games are clean, rubbing alcohol on a q-tip is good, or if you take it apart, a pencil eraser will clean them really good.

Hmm the sandpaper/credit card idea sounds great! I'll try it next time followed by the isopropyl and tooth brush.
