Does anyone have any experience working on these? This is the third one that I've picked up and they've all been bad. This one worked briefly but now it's doing the same as the other two; no video and both the red power light and yellow light are flashing. I talked to a friend of mine that's used these a lot and also says that they don't last long. FWIW I think this is made by Sony and is also used by SUN. Joe
