Rotating selector dial will only select C1, C2, C3 else full auto mode

Has been working fine for 9 years and suddenly I can't select B, M, Av, Tv, P, CA mode. They are all shown as Full Auto mode when selected. C1, C2, C3 works though. Tried firmware upgrade and hard reset by taking out both battery for few minutes.
