simplyretrogamer

Hi everyone Hope someone can help me, I am having issues with my 2600 4 Switch PAL, when I boot Asteroids, the game will appear on the screen but has graphical issues (image attached) and sometimes will change colour to dark purple. Games like Pole Position I can hear it but can't see anything on the TV Screen. I was wondering if anyone has had this issue. Steps I've currently done: Changed the main cap 2200uf 35V and the 4.7uf cap with new ones. Cleaned the pins on all three chips - Chips are soldered not socketed. Change regulator to a new one. Thank you in advance.
