XH1 motherboard and battery issue

By mistake I changed my XH1 attached to battery grip with a third party AC cable. Strange noise and camera couldn’t turn on and i sent it to Fujifilm technical service centre. Technician said grip is ok but 3 barreries were burned as well as motherboard and had to replace it. Then see if the other parts are working probably or need to change more parts! I’m so worry! Any idea? Do you think my camera will be like before this accident? Please share your experience with me. Thank you
