Hi, I'm new here so y'all don't know me. 
I have a question for some experts (obvi). I found this Marantz S4 on Videogon and its super cheap and I'm thinking of buying it but it has something wrong with it. It has these lines that appear on the image. You can find it on videogon for a better description under the DLP projectors for sale section (AVSF won't let me post a link). Anyway, what I was wondering is this a big costly repair, is it something that I could do myself if I had the right part (any ideas of what part is it and cost?), or is it a little blip into the service menu. If I could make it work, this seems like a great deal but I just wonder if its worth it.
