Had my X1 for around 3 years now, but only have about 700 hours on it. Was playing some Xbox last night and after about 2 or 3 hours of play I started noticing the image flickering. It would suddenly dim a bit, then pop back up to normal brightness. It was very slight...the best way I can explain is when your signal cable is a bit loose and the image flickers very slightly if the cable is moved.
360 is connected to the VGA port via the component-vga adapter, X1 is ceiling mounted and never moved. The only thing I've done lately is take out the bulb to clean the screens (did that on Monday), but it played fine for a few hours before I noticed it flicker.
The problem seemed to go away after a while....it probably did that for an hour or so, then seemed to fix itself.
Anything I can do, or is it just "one of those things"?
