|

Its the first time I have ever seen a bad card take out another card. But clearly it was the case this time around.
First my 12xx projector died because a deflection mosfet on the H card shorted out. Then after I fixed that problem I noticed a terrible ringing on the left side expecially apparent at lower resolutions. Apparently Barco designed the deflection switching card with resistors that have fusable leads. And all 3 leads for the resistors for each of the 3 colors were all blown out.
Just thought I would pass this experience along to others who may not have noticed my other thread.
