Sony PS-LX300USB: Speed adjustment potentiometer stuck?

Thu, 30 Dec 2021 16:06:29 -0700

Hey all, I’m trying to adjust the speed on my PS-LX310BT, which has the same speed adjustment mechanism as the LX300USB, and the speed adjustment potentiometer feels like it’s stuck. I can stick a screwdriver into the speed adjustment hole and hit the potentiometer itself, but either it’s stuck or turning it has no effect. I’m not familiar with potentiometers in anything but guitars, so I don’t know what could be going on here.

Sony PS-LX300USB: Fuzzy audio after replacement stylus

Sat, 10 Aug 2019 12:11:20 -0700

I came home and found that the turntable had been switched on and the stylus had been dragging on the rubber mat. I have no idea how long this had been running. Assuming the stylus would be damaged I have put two new stylus' and it is still sounding fuzzy. Could it have affected anything else?

We have a brand new PS-LX300USB but live in Fiji so limited access to warranty and repairers.

Assembled just as advised. No power. Took the back off to check it was all in order. all connections look right but start key doesn’t click and when plugged in and you mannually spin it doesn’t turn on or spin.

any suggestions for repair would be appreciated.
