Question about ViewSonic PJ750 Multimedia Projector
On a ViewSonic PJ750 the "lamp" and "temp" lights both flash red in unison. The unit seems to work at least for the few minutes it was left running, but I'm afraid to leave it on too long if it if truly overheating. I can take the filter out and see that both intake fans as well as the fan on the bulb side are all spinning.
This is a sign of overheating, its a thermal issue, I solved the problem with some compressed air, but absolutely DO NOT blow in the ldc assembly or you will get dust in the lens system. You want to blow the cmpresed air on the electronics not ont he optics. I found that over time dust hair ect collected on the thermosistor and caused the over temp error. Cleaning it resolved the issue.
