OK. I hope you had a nice night’s sleep.
First, I suggest you remove the ICs and power from the circuit. Then, do a complete re-solder of all connections and joints. Replace the ICs and power and retest. If no output, then use your audio probe and trace the signal through the input jack > bypass switch > board IN “T” pad > IC1B pin 7.> IC1A pin 1 > OUT pad “T” > bypass switch > OUT jack. I saw on your video that the LED was flashing, so I believe the LFO circuit is fine. Report results.
