What to do if there is no sound output from promethean PRM-10 Projector?
If there is no sound coming from your Promethean Projector, check IC5001 and its peripheral circuit. Also, verify the 5V_AUDIO and 9V power supplies. Then, check IC5031 and its peripheral circuit. Check the Mute signal at pin 1 of IC5031.
Why is there no power to my promethean PRM-10 Projector?
If your Promethean Projector isn't powering on, several factors could be at play. It could be due to a failure in the primary power supply circuit. Inspect the AC cord, specifically the F601 fuse, the power board, and the SW902 thermal switch. Alternatively, the projector might have detected an unusually high internal temperature. Ensure that the air filters are clean and that there are no obstructions near the intake and exhaust fan openings. Lastly, an issue with the cooling fan operation or the power supply secondary circuits could be the cause. In this case, check the fan operation, power supply lines, and the driving signal status.
What to do if promethean PRM-10 Projector does not produce any picture?
If your Promethean Projector displays no picture, begin by checking the RGB S&H signals at test points TP_B1, TP_G1, and TP_R1. Also, verify the 15.5V power supply circuit and its peripheral circuit. Inspect the PC1/PC2-switching stage, focusing on IC5201 and its surrounding components. Finally, check the AV source selecting and decoding stage.
What does it mean when the LAMP REPLACE indicator lights yellow on Promethean Projector?
When the projection lamp in your Promethean Projector is nearing the end of its life, the LAMP REPLACE indicator will illuminate yellow. Replace the projection lamp promptly with a new one. Remember to reset the lamp replacement counter after you've replaced the lamp.
