I purchased a NEC 6200 XTRA from Hammer Head Tech, unit that has only 2000 hours on the tubes, but I believe the Green Tube has burn. The reason I figure this is when I turn off red and blue I see pure Green on the edges but there is a darker square in the middle is this a correct assumption.I could not find a working link to CRT Burn in the forums Next.. I would like to get my hands on new or rebuilt Tubes. What are the Pro's and Cons of Rebuilt? I can't seem to find them anyway I believe Hammer Head has rebuilds. Are these the correct part numbers for the NEC tubes for this unit? Green Tube Number * 952E1641 Red Tube Number 952E1631 Blue Tube Number 952E1651 Next. I read an article saying that 7" CRT are not going to give a great picture at 100". Now this unit is stock from factory at 100". The reason for this statement was there will not be enough Lumen per foot to give a good picture. I believe the lumen is 1000 for this unit is that true or BS? I have though about making the picture 120 or 140 because I have the room, do you recommend this. Next... This unit has VGA (BNC), Cox and S-Video inputs. Currently Iamb using the S-Video what is the best connection? I have Component on my AV stuff but Iamb not sure what to do. I also have may PC's should I joust use one of them to feed the signal via VGA cable? Next.. On board fans are really loud well i think one is going bad has a light ocsolating sound. Can I replace them with a Pabst fan that's quite if it does the same or more CFM? Next.. (sorry) What should I get a Line doubler, quader? I've search the forums and I find mostly dead links on burn and I don't understand the line doublers etc yet. Lastly then I'll shut up. I have the RC-6051 remote full function, what would I need the user remote for? What does it do, other then just turn on the machine? Is there anything special about it?
