Too vague to even make a start, what was flashing? What sequence was it flashing?

Just check with your meter all the stats eg o/h stat ect before splashing out on a PCB and also check your wiring harnes to the fan I had one last week fan came on for a few seconds them stopped unplugged at the fan put it back and all worked fine.

All lights flashing ain't normal fault condition, sounds like PCB is cooked, caution there are 2 types, 1 with power button on earlier models, then later one without power button on top left!

thats what the MIs say its the control board

Try pulling fuse in spur for 10 mins, if same new board

did that yesterday as it wouldn't reset, in case it was a faulty button or something

Sounds like new PCB then pal......

I had this fault on a new Worcester once, the book says new pub, but it was just a fuse blown on the board!
