I have some DMX disco lights which appear to have the same fault - When swapping a working flash into the faulty units they work so I presume I have a faulty flash chip.

I can get blank chips from Farnell in the UK but not sure about programming.  Do I need to buy a dedicated programmer to read the program from the 'good' chip and write to the blank chips or can I connect the flash to my serial port?
