Lwolffe;

Sorry for the delay, I had things to take care of that could not wait.

I hope that helps.

It is a Mag 900P, with a Product ID of LT982s, Manufactured December 2004.

The capacitors on the Power Supply board look good in this monitor, instead it is a pair of capacitors just to the left of the power connector, on the Display controller which are swollen.

The catch is this: the Power Supply board I am looking at is not...
