Help! Sony Turntable PSLX300USB no sound!

[bmeeker]

I have the turntable set up and I'm not getting any sound! I've got the switch on the back set to "LINE" and the red/white audio jacks plugged into the "IN" ports on the amp. The needle is dropping on the record but no sound is coming out. Please help.

What "in" ports? What amp?

You need to connect this unit when switched to line to a standard line input on a preamp which then connects to a power amp, or a line in on an integrated amp or a line in on a receiver.

If you hear nothing then you need to find a phono input andp lug into into a phono input.

If you have sound then, then the internal preamp/Eq in the turntable has failed. If you still hear nothing then the turntable is a dud.

It's plugged in to the "audio in" on the MD/Tape input on my Sony A/V stereo receiver.

Use a different input. You probably have the tape loop witched the wrong way. Use an AUX or CD input.

Moved the input over to CD, still no sound.

Then you need to find a phono input. I suspect most likely the phono preamp in the turntable is defective, and that test will tell you. Either that or there is a fault in the turntable affecting both outputs. Either way the unit needs servicing. If you have no experience at all of service work, then at that price it will probably be cheaper to junk it.

Turntables are pretty simple, but you still have to know the basics of trouble shooting and be prepared to open the unit up.

What amp or receiver are you plugging into? The turntable (by virtue of it's model number) seems to have a USB output, so have you tried using that?

How are you fixed for metric wire lube? Did you apply a good even coat to the red wires and avoid getting any on the white ones? Those Sony units can be temperamental if you get any on the wrong one. Seriously though, do you have any other equipment hooked up to this same amp that IS working and you can hear it?

...and are the speakers connections verified with another source?

I feel vested here in seeing you win.

If the line out does not work, the USB will not work, as the preamp will be ahead of the analog to digital converter (ADC). I assume the guy has enough sense to know if his receiver is working.

Nothing surprises me and the only thing riskier than gambling, are assumptions.

If you don't have a phono input get out your ohm meter. If you don't have one of those buy one.

Now switch the turntable to phono. Now check that you have continuity from each hot pin on the RCA plugs to the corresponding live pins on cartridge. Now make sure you have connection from each of the RCA shields to those corresponding pins on the cartridge. Under no circumstances connect the meter between a live pin and shield as ohm meters have enough power to fry the coils in a PU cartridge.

Make sure that when you do the test the arm is in the play position.

If there is correct continuity then the internal preamp has failed. If it has, then your cheapest solution is to buy a phono preamp and leave the turntable on phono, and connect your new preamp between turntable and receiver.

If the unit fails the continuity test then you will need to open it up and find where continuity has stopped. On those cheap turntables it is usually a bad leaf switch or something of that nature.

What is the story on that unit anyway? How did you come by it? I assume if not new, it is new to you, otherwise you would be making a warranty claim.
