It sounds like this is one of two problems.
1) It has lost the connection to those inputs entirely. If so the solutions are rather simple. Unplug it and maybe even ground yourself. Open the receiver and check any wires going towards the inputs in question. Also check all the fuses, they should look just like a normal glass vial fuse with the two metal connections. If you can tell that the fuse is dead, find out what type of fuse it is (maybe printed in the user manual or on the fuse itself). Then replace the fuse.
2) If it has to be programed for the particular inputs then there might be a battery dead. simply begin the same way you did with the other solution and this time look for a round battery. It is most likely a 2032 and I would suggest replacing them all. To replace: If it is inset to the board note the polarity, pop it out with a screwdriver or fingers, put the new battery in the same way. If it is raised, note the polarity, remove from the connectors, push the connectors together so that they are slightly closer together than would allow a 2032 to fit passing through(so that it would be snug), and put the new battery in the same way.
