Question about InFocus Projector Lamp for LP340, LP340B, LP350
I have an Infocus LP340 where the lamp powers off in 30 secs after the projecter powers on. I've replaced the lamp with a working lamp and there are no issues with a new lamp. If I put the other lamp back in, the problem occur again. So, I know this issue is with the lamp assembly. The lamp with the issue has less than 200 hours. The status on the projector is a solid green. I can put the projector in standby mode and wait 2-3 minutes and wake the projector up. The projector light will come-on and then power off in about 5-20 seconds. Has anyone experience this problem? It sounds like a ballast problem. Is the ballast part of the lamp assembly? Or is there someone else in the lamp assembly that you cause the bulb to power down after 5-20 seconds? If the ballast is part of project, it okay because the new lamp doesn't have any issues.
If the new lamp doesn't have a problem, then it's not the ballast, it's just a bad bulb. especially if you didn't get it from infocus. the cheaper lamps don't last long. you get what you pay for.
