I got a Color 2 with a box of cables, 8 games with manuals, 2 controllers, books ect... for 20$ on ebay, now, the title said untested, but the other stuff alone is more than 20$. I hooked it up, hit the switch and it made that wonderful (blink) sound and I get this half the time black and half the time scribbly whitish screen. I used the switch box and a coaxle connector, and both do the same. My 2600 works fine with it sooooo......hmmm. I cracked open the case and poked around and everything looks fine but the C36 capacitor has some brownish gunk around the base. I don't know if its just some 30 yr old glue or what, but it doesnt really look like a leak, and the components around it and the board look fine where it is, so I don't think the Cap is leaking. But maybe the cap is bad and thats why I get this screen........I don't have my Multimeter and oscilloscope with me, I just moved to NH and all my stuff is 2000 miles away, Winter is coming and I need something to do while barricaded in, Im from Florida....lol.....and really want to get this working....I took some video and put it on youtube for anyone to look at...hope someone can help me.
