Not getting anything on the screen, it won't coin up and the monitor works. There is 5 volts getting to it. Some of the ics are not putting out the correct voltage, they are reading 1 to 1.5 volts which I have read is called the gray area which means something is wrong. Tried to follow the circuits using the schematics, there have been a few times where I thought I found the bad ic so I replaced it but still not luck. Originally the clock was working, then it started acting up and now it doesn't have any pulse. Thought it might be the oscillating crystal so I changed that but still no pulse. I got the game for $25 and thought for that price I can't go wrong but it is starting to get a bit frusturating. Any help you can offer would be great.
