With no knowledge of that specific scanner, it's common for the radio to switch 
between different front end circuitry, often using PIN diodes. Faults, usually 
dead front end transistors or PIN diodes, will make the radio considerably deaf 
on the related band.

The manual indicates that your radio has 12 different bands. Perhaps you could 
investigate whether the deafness is related to particular bands.
