Before confirm transformer fault, load batteries and see whether it works. After loading batteries, pull out its AC cord from its AC socket at it back side. With AC cord connected at the back of the set, battery supply won't connected to the set. There is a cut - off switch at the AC socket. Only after removing the AC cord, the set will work on battery. Try this. If it works with battery, make sure that transformer or internal mains fuse has blown out.
