For serial 953122, the rear power board is the Norcold 621271001 power board or the upgraded Dinosaur 6212XX. Both fit your 1200LRIM. First check for 12V at the fridge and a good fuse on the board. The 633299 kit is discontinued, so if the front optical board has failed, the Norcold N15DCSS is the replacement fridge.
