Hello,
I recently purchased a used Ecp 4500. I've had it for three days and it was working like a dream. I say was...because last night the blue tube went out
. I checked the tube physically and it seems to be in great shape. No burns or other abnormalities. So I read through the service manual I had located most of in pdf(Thanks to a link found by searching this forum). Just to see if it would turn on I adjusted The G2 for the blue up and the blue tube turned on. Now it isn't usable, the image is distorted i.e.. on a cross hatch the vertical bars and dots are too wide and diffused and the horizontal lines are very pale but accurate in size. I tried focusing the center and edge focus and it helped only minimally. I adjusted for Flare and Stigmator with no success. I am preparing to do a color balance and Video alignment as per the service manual, unfortunately I have to find a voltmeter first. So for now I have turned the g2 back to where it was and shut the projector off. I'm still very new at this( This is my first projector ), so any advice or ideas would be quite useful. The Green and Red tubes are fine. The image they produce is clear and sharp. I can see why this projector is recommended as a first setup. I had it set up and running in about an hour ( it took longer to build the screen, blackout cloth is very good for the price
). Watching gladiator on it from my PC was terrific. I really hope I can fix this. Any help would be greatly appreciated. Of course, if anyone here is in Southern West Virginia and would like to help out in person or recommend a technician in the area that'd be great too
. This forum is great I've been lurking here for a while. Thanks in advance for any help given.
Patrick
