I have a TK1 board I’ve never used before. Yesterday I plugged it into power and an HDMI connection to Insignia monitor that I’ve used hundreds of times for Raspberry Pi projects (well, not hundreds, but enough that I know the monitor is good and it works with other HDMI sources). When I plug it in, the power LED and fan come on, but nothing else happens. The board doesn’t initialize the monitor, doesn’t POST, nothing.
When I push the power button, nothing happens.
When I push the reset button, nothing happens.
Suggestions or is this just a dead board (which is what I think it is).
