Hey guys-
Approximately one year ago our church purchased the LP-500 for the use of PowerPoint projection during worship service. We have also purchased a Samsung DVD/VCR combo player to use with the system. About three months ago, we noticed that the projected image began to 'flicker'. The intensity of this flicker varies from barely noticable to very noticable and there seems to be no regularity to it. In other words, sometimes it does- sometimes it doesn't. I can tell you that when turned on and left on for 4-5 hours, there is very little or no flicker at all. The lamp has 280 hrs. on it.
It may help to know how we have our equipment set up. As mentioned earlier, we have the DVD/VCR combo and I currently have a makeshift monitor (13" tv) hooked up. The projector is ceiling mounted, with the computer cable running from projector to laptop in our multimedia booth in the rear of the building. A yellow ended RCA-type cable is in the composite video jack in the projector. It becomes a coaxial cable with an 'F' connector at the media booth. To this connector the installer added an RCA screw-on adapter.
In order for us to preview and cue DVD's, videos, etc., befor the congregation sees them, I have the coax running to a Radio Shack A/V Selector (A/B switch)"Video Out". A Radio Shack Gold Series A/V cable runs from the DVD/VCR composite "video out" to the A switch "IN". Lastly, an RCA video cable from the B switch "OUT" to the tv/monitor. As you know, this allows the image to be on the monitor, or on the screen, or both- at the push of a button.
Do you see anything in this setup potentially damaging to the projector?
I'm sorry for being long-winded about this, but I hope I have provided some useful information for you to help us solve this problem.
I know this isn't technically HOME theater, but I really need your input.
PLEASE HELP!
