Or is there anyway to test the bulb? I know a multimeter won’t show anything but could I apply a voltage and replicate the ballast? Probably not the ideal situation, and I’m fairly confident that the bulb is not the problem. Maybe my multimeter? I also have my cheap oscilloscope that can handle 400v. I have a good knowledge of circuits and wondered if I could somehow test the ballast for problems. ![]() There’s no physical damage on anything, colour wheel is in mint condition, fans are good, and the glass has all been cleaned up.īallast is a ballast/PSU combo, and the PSU part seems to work great, stable 12v and 5v going to main board. So I am not sure if the explosion damaged something on the ballast or the bulb is defective. The projector turns in for about 30 seconds to 1 minute, and then shuts off and gives the bulb error code.ĭuring this short amount of time I placed my 2k lumen flashlight up to the bulb housing and I was able to see the picture from the lens showing me that it boots and works but no bulb. My buddy did the exact same replacement bulb in the exact same projector a while ago and it works great. Granted this thing did not come with any dust filters or anything and the room it’s in has very poor ventilation.Īnyways, I replaced it with an off brand one, and I cannot get it to light. Specs say at least 5000 hrs on bright setting. ![]() My optoma DLP EH210 (I am 90% sure that’s the model number, as the unit itself doesn’t say) had the bulb explode at roughly 3000 hours. Hey all, I don’t usually do this, as I tend to be able to figure electronic things out on my own, but projector tech is something I’ve never really dealt with before.
