This is a copy from the same post in the high end Projectors. Someone there suggested that I post this here.

Please Help With Vertical lines showing with my new projector

Hello All.

First I am very new to all this

I just received an Eiki LC-X984 (A Sanyo PLC-XP18N clone) Projector

Basic Specs are below:

The problem I am having is: When hooked up to my new Progressive Scan DVD Player (Panasonic RP-82) through Component cables (Blue Jean Cables Brand), the picture has a lot of noticeable Vertical lines running up and down, the whole width of the screen? When I watch something in HD I cannot see these lines? I doubled checked to make sure the progressive scan is turned on the DVD Player and the projector accepts the signal as 480P. Anyone seen anything likes this or have any ideas? Any help would be great. The screen is 100inch diagonal

Run a search using "vertical lines." There are a lot of theories about what causes these lines with LCD projectors. Every once an a while I detect them. I think it's a sync issue bewteen the source signal and the projector. I've notice that when I changed players the lines decreased. ANother member noticed the the lines were evident with his new dvd player (can't remember the whole story-run a search and you'll find the same info).

Good Luck
