I’d first verify that FPGA works and has booted correctly. If you don’t see anything on the LCD and have no response to IR codes (green led blink), then I suggest measuring relevant regulator outputs (U12-14) and ensuring voltage is within +-5% of the spec. If that’s fine, then you could power off the board and check that CLK27 (pin25), MSEL pins (94,96,97) and other essential pins (supplies, nCONFIG, nCE and flash-related pins are correctly connected). If you have a scope, you might also want to check Y1 output as I’ve personally received a couple dead oscillators from Mouser.
