Pcb troubleshooting
I have an atari avalanche which was showing nothing on the monitor except black and the game would not coin up, there seemed to be low voltages on some ics but 5+ coming into the board. Worked on the original board for some time with no luck but then came across one on ebay but the seller wasn't sure if it worked. The new board arrived and I am still having the same symptoms as the original board( i know the board I just got may be not working also). The thing is that the ics on the old board that were showing low voltages the same ics on the new board are showing the exact same low voltages as the original board . Now I am thinking maybe it's not the board? Just wondering if anyone out there has worked on this pcb before and if there is a commin problem that occurs on them.
