Hi All,

I have a Xenon which the playfield feature lamps do not work on. The GI lighting is fine however none of the other playfield lights are working.

For troubleshooting purposes:
1) Prior to them going out, it was an intermittent problem
2) I checked the playfield and all fuses on the rectifier board and they are all good
3) I re-seated the connectors on all boards
4) I have an Alltek MPU and it does not have any red lights on. Only green. All other boards are original

Any help from you guys would be greatly appreciated,

Thanks!
Dave

Well, for starters, do you have +5vdc on test point 1?

Yeah! Another Xenon-er.

I will map the schematic to see where you can test.

A2J3 - 10 to A3J3 - 12 ---> Check A3 TP5 for 11.9 volts unregulated, then check A3 TP1 for +5 VDC +/- .25
A3J3 - 16 to A5J4-3 ---> Check A5 TP1 for +5 VDC +/- .25

If you have power up to that point not sure where to go next. If you had no power at A3 TP5 likely you aren't getting any from the A2 Rectifier board.

The A5J1 and A5J3 connectors go to all of the playfield lights.
