Got an Ideal isar, blank display, not working at all, checked all the usual, power getting to boiler, etc.
Usual suspect pcb, changed both, no change fault still same.
Before me customer had one of them handyman plumber dudes to have a look, apparently it was working and showing a fault code, and then he touched it and blew something and ran off.
I don't know what he's done, I've checked wiring, etc
Anyone any ideas, for what it might be? Maybe something obvious I've missed.
