Still working on my atari avalanche pcb, when you turn the game on all you get is scrolling raster lines down the screen, the game has a self test mode for the ram and roms and switches. When you turn on the self test I never get a message regarding the ram or rom like the manual says but sometimes but not all the time the switch test works. Also if I turn the game on sometimes only the light on player one lights up and the game makes a horrible squeling sound. This is the 2nd avalanche pcb I have and it has the same symptoms of the first board that cam with the game.
