The Lamp is not lighting, there is no indication of audio. The front panel LEDs, Lamp, Status and Pwr act as if the unit goes straight to power saver standby mode with the pwr LED blinking fast as soon as its plugged in. Pressing the power button does nothing, pressing the reset appears to run it through the same routine as plugging it in. At least it sounds that way.
I purchased a service manual and to trouble shoot I’ve done the following:
Verified the power supply that supplies the 370 Vdc to the lamp power board present at the correct point.
Exchanged the lamp with a supposed good one. When the lamp was removed I did get the correct “defective lamp” indication at the lamp LED.
The svc manl says that if the 370 Vdc is is present going into the ‘lamp-sub-board’ and the lamp does not light to replace the board. My questions:
Is the “lamp-sub-board” dumb board? Meaning just put power to the input terminals and it fires the lamp?
