I have bought a CRT monitor off of a colleague, NEC accusync 90, and it seems to work ok except for it only has the red/green components of the color.

she says it was fine the night before so I assume there is just a wire tht has come of in transit or something.

Could someone point me in the right direction for parts to check.

Thanks,

(I have checked that the blue is turned up and that it is the same with mutliple computers, also the OSD is in blue so the screen itself is working.)

Check the signal cable plug/s for a bent pin.
