Along this last summer I've been repairing a friend's colecovision (Hi Armando!) and it turned out to be a nightmare. The Colecovision was really in a bad shape, worse than expected and after more than two months of checking and fixing, here's the result:

The Coleco ended up being mostly socketized, the list of damaged and replaced ICs is long: U10-U17 (all 8 VRAMs!), U5 (74LS138), U9 (TMS9928), U21 (LM1889) and U23 (HEF4066). Basically seems that all the video generation system was strike by a lightning!

 

Here's a close-up pic:

Congrats on tracking down all of the issues and for fixing them.  I suspect many would have given up.  I love seeing old game systems saved from being thrown away.

 

Well Done !!!!!

It was a "machine vs. man" fight!  :twisted:

It's no my Colecovision; but I'm sure that my Adam would be happy with a Risky Rick plugged in!  :D. Since I talked with Richard about it I was hooked by the development, incredible feat!  :thumbsup:

Wow, so good to see it repaired, so many faults would have seen it in the landfill for most people.

My own power switches turned up tonight, which means I can finally play with a clean picture, and get the thing reassembled! Really looking forward to seeing it all it's Russian suitcase nuke 80s splendour.

Yep, definitely needs its original heatsink, it gets hot very quickly!. I've glued the metal with high quality thermal paste and some thermal adhesive so I suposse that it must work a bit better than before

Sure, the Adam is still opened and waiting for a new VDP, thanks! :)

Thanks!! But shipping cost is 15.95$ to Spain. Will continue looking on local dealers, but is good to know where to find heatsinks, maybe buying a large quantity will make shiping costs more affordable.
