Here's a problem I've not seen before.  I have a 4 switch that once you turn it on works brilliantly... for not even a full second.  It then goes wonky and/or dies.  I had a new voltage regulator sitting around, so I figured why not throw that on.  I know a bad one can make a system crash, usually after more like 15 minutes but I figured why not try it.  But it made no difference.

 

If I'm lightening fast, I can hit the Reset switch in time and see that the game loads successfully.  Channel select switch works.  Color/B&W switch works.

 

Any ideas before I continue throwing crap at a wall and seeing what sticks?

 

Thanks!

This affects all games?

Might be cracked solder (reply #4) on the power socket.

It effects all games, yes.

 

I reheated the joints on the power socket for good measure, but it's not that.  It's not really losing power, it's almost like it just loses the ability to read a game.  It responds the way a non-functioning games does.  Either a black screen or a bunch of waves lines, or maybe a combination.

 

It may be worth saying that if I turn it off and back on immediately, the game probably won't load at all, even for a split second.  But if I wait a few moments, it will.

In case anyone is curious, I continued throwing more crap at the wall and something did indeed stick eventually.  Turns out it was the CPU chip.  Very interesting.

Glad you got it sorted out. I was about to suggest you might check the chips. I had to swap mine out about a year ago..

I have had so many bad cpu's refurbing 2600's its usually the first ,and  about 8 out of 10 times, the last chip I swap, I think they get a little toasty, it couldnt hurt to slap a little self stick heat sink on the center of them
