Okay, so I bought a 2600 Jr. with 41 games from a guy on Craigslist for $30. He said it worked the last time he played it, which was about 2 years ago. I took it home and plugged it in, and (surprise!) it didn't work. I've spent time googling all day today and yesterday, and can't find a solution to my problem. I've hooked it up to an old CRT, and when I turn it on I see the game and can hear the sound for about half of a second before it cuts to a black screen. I've tried using a different RCA-Coax hookup at a local retro store, still no good. Plus, the RCA-Coax it came with works on my NES. (Yes, for those wondering, it's a manual switch box) So on to solution 2. I tried cleaning the contacts via rubbing alcohol and q-tips on a cartridge and putting the game in and pulling it out several times. Still no good. I've tried multiple games, and I get the same thing every time.
I'm going back to the retro store to try using a different power adapter tomorrow, the one that came with it doesn't warm up when plugged in, but the light on the console comes on. It's really hard to tell when the cover is on. Is this normal for the Jr.? Oh, I also cracked it open and aside from a few rust spots here and there, it looks to be in pretty good condition. All the soldering is solid and I can't really see anything wrong with it.
I was just wondering if anyone could tell me if I'm wasting my time trying to fix it. I'm hoping it's not a chip problem, but I don't know much about the 2600 to tell.
