A good LPRO works both with cover on or off. > Q703 voltages look good (with cover off and unit working). Lamp color seems good (slightly pinkish violet). The room that I am in is lit by DC halogen lamps so not rippley light to worry about.
If the power to the halogen lamp comes from battery, really no problem. If it comes from mains + transformer + rectifier it remains suspicious. My last suggestion: check R705 (100K) and R732 (100K) on the bottom of the PCB. R705 should read some 84K onboard, and R732 some 100K. The lettering around R732 is a bit ambiguous, so look for a 100K resistor in that area.
