Default Anybody have service info for Eizo (Nanao) monitors?

I have a 21" Eizo T962, with a horizontal problem.
Background without signal is purple and will sync fine with DOS screen.
But starting with windows logo, it goes totally sideways and starts rolling
from bottom to top.
Pressing the Auto resize turns off picture and standby starts to flash
rapidly.

It seems to be impossible to find any schema's or service info on these
monitors.

There is no service information or replacement parts available from the
manufacture.

Most of the time, the failures are many of the electrolytic capacitors
become high in ESR over time and use. Use an ESR meter, and test all the
capacitors in the monitor, especially in the scan (H & V) amplifiers. This
should include the blanking circuits, CRT drive circuits, and the HV
generator circuits.

In these monitors, as for the picture turning purple in the background, this
is usually attributed to the CRT starting to go weak.

Well, that's interesting policy for a company. I'll be sure not to buy (or
recommend) their products again to anybody. ;-(

Anyway, thanks for the info. :-)
