Yep, free. I was shocked. I offered the shop owner money both before and after I got it working. He refused to accept anything for it. He was impressed I got it running. I guess he has a local guy that repairs dead consoles that declared it unfixable. The board was corroded pretty bad. I'm sure it looked like a lost cause. I cleaned the entire board with deox and a toothbrush. I regularly spend between $20 a $100 a month in his store. So we have a pretty good relationship now.

Nice. :-) All you need really. :-)

For me it was a perfect storm. Used a volt meter to figure out the power brick was bad. After that I discover the switch needed cleaning. After that... The potentiometer in the RF box needed tweaking. Finally got a (remarkably good) picture but it only works on channel 4. Then I played Donkey Kong for 2 hours. :-) Thanks to everyone here that each gave me something helpful to look into.

Awesome score! And I've subscribed to your channel! :-)

Scored a free ColecoVision complete in box. Totally non-working. Got it fully working after 5 days. Used deox to clean all the contacts and the switch. ReAdjusted the potentiometer to restore the video out. The power brick was dead so I replaced it with a PC power supply. No mods to the console itself were required. Cleaned up the console and controllers with a toothbrush. Looks and plays almost like new. (The controllers switches are very sticky). Works great with genesis controllers.

Very impressive! I have: NES NES converted to a copynes Genesis model 1 (controller port 1 only works with 6 button controllers for some reason) genesis model 2 ColecoVision (given to me completely non-working. Restored it and replaced power brick with a PC power supply.) 2 Atari 6 switches (1 has a broken reset switch, maybe it just needs deoxit) Super Famicom SNES Super gameboy Xbox (DVD drive was shot. I replaced it) Game cube Game boy player for game cube N64 Playstation 1 (broken because original owner fried the board trying to mod it) Playstation 1 (working and modded, from the same owner as the broken one) Playstation 2 Playstation 3 fat (no PS2 compatibility) Wii (with Game Cube compatibility) Game boy Game boy Advance (shattered screen) Game Boy Advance Nintendo DS (broken hinge) Dreamcast Retro Duo Portable V2 Retrogen Adapter PSP model 1001 PSP model 3000

Would it be possible to go the other way? I have a Sega Arcade stick I would love to use on my NES.

Thanks for following up. I have tried a new power supply but it does not fix the issue for me.

Did you ever discover what the source of the problem was? My coleco does the same thing. The static just changes color. I have verified the board is getting the correct power and that the switch is making good connections (with a volt meter).

Best of luck with this project my friend. I have a CV (complete in box) with a broken power supply and dead motherboard. The thought of being able to bring it back from the dead with mostly new components is awesome. I'm looking forward to the stage where you are ready to accept pre-orders.
