I don't know the problem. The technician said its faulty .I cannot see anything obviously wrong with that PCB are you sure that is what needs replacing?
Yes i think is this number.I guess it was last seen in front of your camera.
Are you after a new one? Are there any part numbers or manufacturer's names printed on it?
Good point - failures are often indicated by physical signs on a PCB (signs of burning, tops off capacitors etc) - what's the fault? Likely components that fail are power devices (Mosfets etc). For what they cost it might be worth replacing them if you can find find cheap rework technician! Other problems can be dry joints - go over board with a magnifying glass. Is fault permanent or intermittent?I cannot see anything obviously wrong with that PCB are you sure that is what needs replacing?
