I know this monitor relates to a Mitsubushi Diamond monitor, but dont know which. One of the colours (blue) has dropped on this monitor, and I have traced the problem to an amplifier via substitution. The amplifier in question is a VPA15. Im having real trouble locating a replacement or equivalent. It seems a waste to throw a good working monitor out for such a small component.
I would appreciate any help here in locating the component or equivalent.

Thanks

I have the same monitor with the same problem except it is Red that has dropped off. Did you ever find a source for the VPA15 amplifier? If not I'm going to chuck mine anyway if I can't fix it and would send you the VPA15 amplifiers off mine if you want.
