I've replaced the lamp, P module, and B/Q module. After pressing the power switch the projector goes into standby mode (blinking green power indicator), but never fires the lamp (solid green power indicator). After a couple of cycles of power indicator blinking green, the lamp indicator goes solid red. The service manual troubleshooting guide has me check A6 pin 12 LOW to HIGH (check), and A4 pin 2 LOW to HIGH (check). No 390V DC emits from P2 pin 1 to fire lamp. No 15V DC emits from P2 pin 4 to power B module. That's the end of troubleshooting flowchart. Thermosensor is fine (temp indicator off). Please help if you're familiar with this unit. I've sunk too much $$$ into this repair to give up, but I'm out of ideas. Thanks!
