A FPGA (Altera), which presumably acts as either video decoder, or video card, to control the LCD panel.So we started prying open the case to look for the components that may give some hints, as to how to revert to a working device The projector failed to flash the file into his flash properly.The firmware was in contrast to it’s description, not meant for this hardware.We assumed there where two possible reasons as to why the projector didn’t function anymore: So he inquired as to what his options where, grabbed some beer, and started googling like mad-men. and was disappointed, the watermark was gone, but also the rest of his projector functionality, he bricked it. So when he encountered a supposed update for his projector (which was hosted on Facebook), which made the watermark optional, he took a leap of faith….
