The headphone plug broke off in the jack and I can not get the end out. is that what could be causing no audio at all? this is a Casio Privia music keyboard px400r

I would say yes. Especially if putting in the headphones cuts out any external speakers.

The Casio Privia 410r has two pedal jacks at the back. One is the sustain pedal, the other is the soft/sus jack. Please use the other jack if you want to use sustain pedal. Only 1 of the 2 jacks can be used.


However, if you have the optional sp30a pedal which plugs UNDER the piano instead, then only can you have 3 different piano pedals.

Try recording sound through the headphone jack rather than using the MIC.

usual problem with casio
the solder broken in dc jack in to the piano

YES. Either plug in headphones into the headphone socket. There should be a switch on the back which disables the speakers as well. A simple ON/OFF switch for speakers

Plug a set of headphones into one of the PHONES jacks on the left side of the unit.

First thing is to get a meter and verify that the power adapter is producing voltage that it is supposed to. You can get inexpensive meters at Harbor Freight for example. I am not sure what you mean by "several outlets"... I HOPE that is not several on the Privia because there is ONLY ONE correct place to put the adapter cord into the Privia.
If you mean wall outlets, verify them by plugging in a known good lamp or appliance to check the receptacle is good.

If I were to venture an educated guess I would vote for failing filter caps in the power supply.

The power is likely collapsing under load of the speakers but headphones take much less drive.

If this has an external wall-wart power supply, you might try a new one IF the output is found to be under the rated voltage.

Internal power supply components are beyond those individuals that are not adept at electronics.

The keyboard has a mic jack that is the same size as the headphones. You probably put the headphone plug into the wrong jack is all.
