PT-100 Phono input left channel is dead

[alpemomo]

Hi 

I noticed that my phono input on pt-100 the left channel doesn't produce any music.  AUX, CD and rest work perfect but not the phono input

Has anyone experience this or can help me?

I would suggest swapping the left and right interconnects coming from the turntable - to confirm that the PT-100 is at fault.

Cartridges can lose channels...
And there is some very delicate wiring in the turntable and tonearm...
And even interconnects can fail.

Since the signals from a cartridge are very low level even a slightly oxidized interconnect can be a problem.
Therefore, before anything else, I would try unplugging and then reconnecting those interconnects in particular.
Also check those little tiny connectors where the wires in the head shell connect to the individual pins on the rear of phono cartridge.
(They do have a way of coming loose, or falling off, or even breaking.)

Beyond that there's not much that would account for that other than an actual hardware problem.

Thanks Keith

I did all that already, I also hooked up to the aux line with built in preamp on my TT and worked fine.  I also connected my cd player to the phono line and same issue
