Hi there Coleco Dan, The seller said the console was fully working and we tried to work something out (if i returned it though i'd have ended up nearly £200 out of pocket because of the original postage, return postage, tax etc and would only have got about £50 back) and then accused me of trying to cheat him as he didn't believe there was any problem even though i'd sent a link to a video showing what was going on. Ah well, it's the first time i've got a bad console in all the years i've been collecting ... these things happen to us all at some point unfortunately. Hi there 5-11 Under, I adjusted the potentiometer from closed to fully open but all i can get is a black and white picture unfortunately. if I open it up fully the picture gets really bad but when open about a third I get a nice clear picture but only in black and white. I'm not an expert with fixing things so to be honest I'm not sure I could follow your suggestions although i'll do my research and give it a go! Hopefully what you've suggested will cover what is going wrong and means I can get it working in colour now. :-) Cheers to you both for your help with this, Craig x

Hi dragonstomper. Thanks for the tip mate. I connected the Coleco to my TV using the AV inputs instead of via a Scart adapter but the results were the same. A black and white picture instead of colour ... I also haven't been able see any loose wires within the mod itself (the only loose one seemed to be the potentiometer connections which i fixed when i replaced it) although I'll be able to have a closer look tomorrow in the daylight just to be sure. Thanks for the advice though, much appreciated! :-) Craig

Hi all I recently got my hands on a modded Colecovision console with a pause button, new bios and av mod. Unfortunately I had problems with it from day one and had to resort to trying to fix it myself. I got it imported from the USA to Scotland so sending it back for repair was going to cost me a lot more money and I'd already paid a fair amount for the console and then for games and a flashcart. The original problem went like this. When using the AV mods I could get sound once i got a game running but no picture. If I used the RF output i could get a black and white picture but no sound. You can see what i mean if you download or view this video : www.satellitedub.com/colecovision.avi It shows the RF output then the AV output then back to the RF output. I opened up the console and there seemed to be problems with the 1K Potentiometer. I got a new one and fitted it into the console. Now I can get a picture and sound using the AV output but it is only in black and white not in colour. It does the same thing on 2 different TVs. I tried moving the channel selector switch from 3 to 4 but it didn't make any difference. Also there is now some background noise and a slight whine when playing games which wasn't there before! Anyone got any suggestions for what might be wrong and what i should do please? My TV is NTSC compatible and plays my other NTSC consoles (neo geo aes / mvs etc) in colour without any trouble. Thanks in advance for any advice, Craig
