I have a k7000 std rez. in my mk2 cabinet and have not had it on for like 6 months. Well today I turn it on to find the picture collapsed vertically and partially horizonatly. Well the picture is about 3 inches tall vertically which to me should not be a flyback problem, but anyway i took another known good k7000 and replaced it with this one and im having the same problem. Any ideas?
 
If both chassis look the exact same then I'd say you need to check out your yoke. Do you have another tube that you can attach these chassis to?

Just to clarify....
So you removed a known good chassis out of another monitor and put the one having a collapse issue into that other monitor? (different yoke, different tube)
If so, then that means the problem is just on that particular chassis.

If you put a known good chassis into the same monitor that the bad one came from and it still has the same problem, then yeah, check your yoke wires and connector first.

And was all this swapping done with the same remote board or anything like that?

I took a good chassis from another tube and put it on the one in my mk2 machine and it has the same issue so it is not the chassis. I did however use the same remote board as I lost the one from this good chassis.
 
could be a broken remote board(pot) or wiring too perhaps...

however, before you waste too much time here lets at least meter the yoke..

ohm between yellow and green, red and blue, post your results.

Ill have to remove the monitor from the cabinet probably because i dont think I can get to it from inside the cabinet.
 
I sell brand new remote boards for $17.50 shipped for the k7000's if your interested.
