You do not say the boiler details - just PCB
You may not need a circuit diagram
They commonly suffer broken down electrolytic capacitors and dry joints

A digital photo will give you confidence when you come to put it back together

Here's a link to a pcb repair on a Potterton Profile...

Good luck...
