I'm getting frustrated with my Barco G801. I cannot get it to hold convergence. I always let it warm up for at least an hour using the solid white field from the Nokia monitor test program, but to no avail; the convergence has to be tweaked before every use. Does anyone have an idea as to why this is happening? I love the picture quality of the CRT, but if I have to keep this up there may be a bulb pj in my future (I hope none of my local HT friends read this, I give them crap about their inferior bulb pjs).
