Ok. I found another short on U16 – that’s the last one and also I found one of the 0.1uf caps at the corner of the FPGA was lifted on one side.
After fixing those, a reflash of the FPGA went 100% write and then 100% verify.
I switch it on annnnnd…
The LCD lights up (no text), the RED led comes on and the unit switches off. All within 1 second.
Also the same thing happens now with the JTAG inserted so basically it is now bricked.
