Monotron Delay - "Delay" part stopped working

[evanowe]

I dropped my monotron on the floor, and it has stopped function as usual - so basically I got just Monotron now, without the delay (feedback-time) part.
I disassembled the case but didn't see any physical damages to the PCB. But I'm noob in electronics.
What might happen and how can I fix it?

sorry for the necro-bump, but I'm having this exact same problem. Disassembled the monotron and saw nothing wrong in the PCB. Any tips on this?

With the small size of the SMDs (surface mount devices) and the very thin connections on the PCB, it is doubtful that you could identify a hairline crack or a broken SMD contact by sight without access to a magnifying glass. On top of that, the damage can be internal to one of the components. Tracking those faults requires access to at least a multi-meter, and preferably an oscilloscope. Repair requires soldering equipment and possibly even experience in soldering SMD components.
