Probably cracked soldered joints on control board. Shouldn't be that expensive to repair. Can't say for sure because A. I don't know where in the world you live. Different countries = Different prices. B. Don't know how much your local repair company charges. Suggest you phone your local service company, describe the fault and ask them for a rough idea what it will cost.
