I lent my 701s to a friend as I was off on holidays for Xmas, the image from the PJ prior to this was very good. However while he was setting it up there was barely any image being projected from the green tube. I got it back last night and decided to have a quick look at it today between packing and lo and behold the is virtually no image being projected from green. If you look down the lens you can see the green image, but its very dim. This is the image from the HTPC, to the barco using a vga to 5 bnc cable and on the barco the H&V connect using a BNC y splitter. If I go to the adjustment menus, green projects nice and strong. Any pointers to what may be wrong? Thanks V.
