2 weeks later and the monitor is still going!

It does have one other peculiarity though... When I turn it on it takes ~5-10 minutes for the brightness to stabilise. It's very dim to start with (even with brightness on max) for about 30 seconds, then I need to slowly wind the brightness back over 5-10mins as it gets way too bright. I swear the focus drifts a bit during this time too; not badly enough you cant read things on the screen, but enough you notice it. The focus does readjust using the trimpot; but like the brightness it's almost like it 'warms up' and requires little adjustments over time.

Any usual suspects for this behaviour? I can live with it; but it would be nice to see if it can be solved.
