HI Habsraj,
Sounds like you require a second opinion but not from a Baxi engineer just yet.
Ask a few mate to see if they know anyone who could have a look for you. He may look at the problem you have with your boiler and maybe he will look at it from a different angle if you know what i mean. If its completely dead then the fault should be easier to find. In theory !!
Oh, by the way, how much did the PCB cost as i have also been told the problem i have is down to the PCB!?!!
Cheers
