Probe 1 doesnt respond to any input..., ch 2 seems ok. BNC connector was loose and wire to resistor broke loose +Wire from resistor to BNC connector was re soldered nut tightened to BNC, and was working fine. Repair still looks good but ch 1 trace just a flat line can only adjust location of flat line. afraid to adjust internal pots in fear that I am making things worse. Channel 2 is working good responds to testing and calibration and internal pot adjustments. more in depth repair? or More aggressive adjusting? any thoughts?
Hitachi v152F probe 1 trace is flatline no change in trace

Blown first transistor or corrossion in one of the attenuator switch actions, no pot twiddling will resolve it. Can you swap a screened lead somewhere inside ? like checking left and right amps of a stereo unit
