More info on last post for HLS4266w shut down
Posted: Mon Feb 22, 2010 6:05 pm
I have some more information that may help with my issue. The lamp is a Phillips brand. I removed the jumper that I used to short the ballast and then checked the color wheel rpm voltage/Hz using the specs from one of the other posts. It is reading 240Hz but the voltage varys from 8v to 1.1v. I'm not sure which pin #2 is, so these readings may not be right. Does anyone know if the lamp should stay on indefinitly while the ballast is forced on, or does the ballast still pay attention to the O.K. signal(I think 5v but not sure what pin to check) from the DMD board. If it should stay on, then I think the ballast is causing the shut off issue.
Any help would be greatly appreciated!
