I have a 25in. K7000 chassis, that when powered on the picture is sharp, but after about 3 minutes the focus is WAAYYYYY off and the focus knob on the flyback doesn't fix the issue. Could this be related to something else or is it solely isolated to the flyback? thanks for any input.
 
seems like a flyback issue to me.
Does your flyback have white knobs? Change it anyways if it does.

It's only $20 from bob...
 
I had this issue once....the fix was to re-solder the focus wire going into the neckboard socket. It can also be the flyback as noted in the earlier post if the issue persists.
 
generally flyback going bad.

if the focus changes on its own, or you have a very small window to adjust the focus, then it's probably going bad.

K7000s you don't want the flyback to go bad, cause they do a substantial amount of damage when they do. :)

so stop using the monitor and replace it, especially if it has white knobs. if you want any advice on how to do this you can PM me.
