Am I the luckiest guy in the world? I just got a Sony VPH-D50QM for free. It's been used at work for a few years so I'd expected the worst but it turns out it's in good condition and it's got less than 300 hours on it (I don't think anyone could be bothered to wait 20 minutes for it to warm up so it was hardly used). Anyway, to the point. I've had a good read of the installation manual and played with the adjustments a little and I have a few questions: 1) I've been trying to get the basic manual convergence and focus set up and I don't seem to be able to get the blue in focus. I've read elsewhere on the forum that the blue should be slightly out of focus but how much is too much? 2) If I do need to sharpen this up, then I assume I need to adjust the blue focus pot (I've located this on the side of the unit). The Sony installation manual doesn't mention this at all, is there anything I should know before I mess with it? 3) When doing the manual convergence should I be able to overlay the two colored crosshairs entirely or is the aim just to get the main vertical and horizontal lines to overlay as closely as possible? And finally, can anyone recommend a good, cheap pull down screen (4/3 ratio)? I appreciate that's a lot of questions so any advice at all would be gratefully received. Thanks, Chris.
