IF controlled lamps on the playfield either stay ON or stay OFF but its NOT a wiring issue, lamp socket issue, bulb issue - its the transistors or other issues on the lamp driver board. I had a Xenon that did this and I traced it down to about 5 transistors that were bad and a bad trace on the board as well. The manual has a very clear diagram of what transistors control what lamps so its pretty easy to test them and track this down.
