Hey all.
I have a pole position II that quit working on me again.
Anyone in the Sacramento Ca. area able to troubleshoot it ?
The boardset has been worked on a couple years ago by Dick Millikan.
Screen just comes up with garbage now.
Let me know. Thanks, Rob.
Cant get pic to load :(

Checked all the usual suspects.
Board has +5.1 volts coming in. Fuses on power brick are all good. Since the board was repaired a few years ago, I did not worry about the edge connectors. Checked anyway and all good. Since this is a PPII, did not find a battery on the boards, so no acid damage.
Might go ahead and change out a couple RAM chips , referencing some older repair posts and see what happens.
 
Ok. Did some work.
Replaced RAM chips at 7J , 7K with new chips and sockets.
Still get RAM 6 error.
Any ideas what to check next? Boards have 5.1 volts from a separate power supply.
