I am new to this forum and am hoping I can learn about classifying this stuff on my own, but as it stands I have no idea what I'm doing. I disassembled a large venue projector, which is full of boards. I am in the process of removing heat sinks, etc. These are one of the boards and I have not seen anything similar in the price list examples. The included photos consist of front and back of the board after I stripped everything that was held on by bolts and screws. How should it be classified?

That would be a DLP chip sir. I would remove that chip (the one with the gold surround) and put it in your DLP chip pile. Then the board would be a high grade peripheral. Those DLP chips are worth pretty good money ($30.00 per pound if it's ceramic and $8.50 per pound if it's metallic). So it's worth separating. Pretty sure that one is ceramic.
