Can anybody tell me what the green LED on the BG808s neckboard indicates? I just noticed the LED for the Green Tube is off, but both Red and Blue Tubes have the light on. (Seems to me they all used to be on...)
Projector still appears to function properly.
Thanks!

Those are there to indicate a proper G2 voltage of the tubes. The potentiometers are to be found on the G2/diagnostic board, just behind the focus block.

If the leds are lit or not during normal operation, is irrelevant. They should be off only when in G2 adjustment mode (service menu). Page 37 from the installation manual describes the procedure well.
