I am using a hanterex mtc9000 in my cabinet but have  aproblem somewhere.When the machine is left on for a length of time (a few hours i mean) the monitor appears to lose one of its colours and the screen turns very bluey!!
Any ideas guys?

I don't know much about Hanterex monitors, but from your description it sounds like a bad solder joint(s) on the color driver transistors (usually located on the neckboard).  Check your monitor schematics.

Also check the solder joints on the main board header where the gameboard connects to.  This is also a common color failure point with various monitors.

Since the problem only occurs after the monitor has warmed up for a while, I doubt you have a problem with the tube.
