I have a ColecoVision console that I recapped a while back (within the past year). I don't play it much, if ever to. E honest. But tonight decided I wanted to. However, tonight it's exhibiting a very odd behavior. I can sit here and play a single game no problem for 2-15 minutes. But as soon as I turn it off and put in a new game, when it powers back on, I have 45 degree lines all across the screen.
But, if I turn it off for around 30-45 seconds, then power it on, everything is fine again.
Leads me to believe it's some kind of heat related issue. But, I can seem to play a single game fine indefinitely, and the issue only occurs when I turn it off and back on again in short order (less than a minute) that I have problems. Which doesnt make sense that it is a heat related issue, as the problem should show up while I'm playing a game for several minutes. But it doesn't until I turn it off and on again, even if the game I was playing was for only a few minutes.
I have a second console, and while it has its own issues (the RF jack seems to have a bad solder joint, as I have to wiggle the same RG6 cable around to get a good signal), it does not exhibit the same issue with 45 degree lines after warming up and changing games.
That to me means the power transformer is good, as is the RG6 and the second console (except for when you wiggle the RF cable). So that means something odd is going on with the first console. But it doesn't make sense if it's heat related why I can play a game for over 10 minutes with no issue. But as soon as I swap carts, I have to wait to power it on again. Until I let it cool for 30 seconds or so.
The power switch has been cleaned with deoxit. But I don't think it's the culprit based on the behavior. The console was also AV modded, but shouldn't matter as I'm ramming the RF signal into my tv via quad shield RG6.
