Fixing Lepai LP-2020A+ amplifier that would not turn on and just blinks instead

My Lepai LP-2020A+ / LP 2020 A+ started acting up, having trouble turning on (does turn on intermittently). The blue LED would pulsate / blink and the relay would not click. Sometimes the unit would turn on after a while, or after turning on / off cycling a few times. The culprit is cracked solder joints where the two wires from the power switch go into the PCB. Wiggling the wires as shown in the video results in the unit turning on. Resoldering the two pads shown with the screwdriver at the end of the video seems to have fixed the issue (in my case, anyway).
