I need some help please.
My Sony display has developed a E-W Pincushion fault. If it was a piece of equipment with a power supply or audio fault I think I would have cracked it by now. But this one is beyond me as I have no idea where to start looking for a faulty component. I have a multi-meter and a soldering iron. I know most of the components and how to test them in and out of circuit. Any help to where and what to start checking for will be greatly appreciated. Thank you.
The display is a Sony Trinitron Multiscan 520 GS, Model: CPD 520 GS.
