Channel coupling sticks on DC

Post by andy53 »

Hi i recently bought a PICO2204A to help with diagnosis of faults on an old 1930's Radio i'm not sure if i inadvertently damaged one of the inputs when i was probing some high voltage signals.
the fault is only on channel B and wont switch to AC coupling. the display remains as if it is DC coupled.
this means i cant see the RF signal which is considerably smaller than the DC Bus voltage.
any help please
