Games fault after 10-15secs

I've powered my Sunnyvale after few weeks to try some new cartidge I've purchased. Starting from one I was sure works: space invaders. Well I see at first sight there's something wrong. The 'invaders' start to be fuzzy and the gamer ship disappears, fire few contimeters far.. Resetting the game does not work, must turn off and on but.. The issue starts after couple of second.. And all other cartridges are the same.. Starts ok, play few seconds the start to glitch.. I've already replace the CPU with a working one because this console cames with black screen.. What can I check? It's the first time that the consolle fails in this manner. Never had this issue before..

I'm no expert, but sounds like the electrolytic capacitors need to be replaced. That said; I would get a second opinion.

Omg.. Other issues:

Mario at start screen glitches the main title, during game mario disappears

Berzerk starts the game with the player over the wall, so the 2600 starts to buzz, if it starts the player disappears

Ikari start well, after few seconds the player stuck on top, only can move left and right but it fires continuously.

Damn!

You think that It can low down the regulated voltage?

Interesting..

More likely there's excess noise and ripple on DC power causing glitches. Plus 40 years old cap... those are cheap to replace with good quality caps.
