Help fixing a broken unit with overvoltage

Hello.

I supplied about 200V directly to the scope by accident, and the A, B waveforms are not showing up now.(the waveform lines are not visible) I can see only channel C, D working.
I suspect the HWD9288 ADC is broken but it seems there's no easy way to get one. Is there anything I can do to fix this problem? Thanks in advance.
