Can anyone help me find a technician who can remove a nagging horizontal line that runs up my screen? It starts at the bottom, goes to the top, and continues over and over. It looks to be a blue/green line, maybe 1 pixel wide.

Or give me some tips on how I might tweak this thing to get rid of it.

Thank you,

Wrong forum, but it sounds like you have a ground loop. You need a ground isolator for your cable/satellite system most likely, you can find those on ebay for cheap.

Wow, I'm pretty amazed there are 400's out there still. My first proper HT pj was a W400 back in the late '90's. Nice little unit back then.

Mine is still up on the Ceiling in my theater, 20 feet back while my 2 Marquee 8500's are about 7 feet from the same size screen.

I dont even know if it still works .

What's the proper forum for this post? I haven't been on this forum in almost 8 years1
