I have one of these, and it no longer projects an image. I have 12.1vdc at the motherboard where the positive and negative wire are soldered in.
After de-soldering the wires, I used my bench supply to put 12vdc to the wires, still nothing. If I apply power directly to the COB, the COB will illuminate. What is the silver component held to the heat sink? Mine is labeled ‘Kavass BW-80B 250V 5A’. I have not been able to find ANY documentation for that item to be able to determine what it is, does, or what a suitable replacement might be.
