I found it on eBay.   It was £60.
 
	 
 
	I was getting a bit desperate cos couldn’t get a new board anywhere, even the manufacturer wouldn’t sell the PCB only.
 
	I could only get it new as a kit with outer case, and a keypad. Wasn’t going to pay that cos I’d already bought a new keypad thinking that was the problem.
 
	 
 
	I suppose I was taking a bit of a gamble that it was fully functional, but there are some honourable people out there.
