Working on a DE WWF machine. Had the CPU out for about a year and now I am trying to get it to boot. Here is the break down.
1. Turn on power PIA and 5v leds light and stay lit, blanking never lights.
2. I get the start up phrase. "Welcome to wwf blah blah blah".
3. Display is blank. Got a little garbled garbage at first, but now nothing.
4. I have replaced the PSB and the CPU boards with working ones and switched the game eprom for the cpu board, still having all the same problems.
5. I get 4.98v on the PSB, but 4.88 on the CPU.
6. Unplugged everything on the PSB except power coming in and CN6 which goes to the CPU board. Unplugged everyting on the CPU board except CN17 which is for the 5v.
7 I am still getting the same led lights, and 4.88v on the CPU board.
Should I be suspecting the connector CN6 on the PSB and or the connector on the CPU board at CN17? Anything else I could have missed?
Board work just isn't my thing. Thanks for any suggestions.
