Question about Casio Music
Check that the front of the keys is not hitting the lower plastic case front. If they hit it, then you need to disassemble the case partly and see what has shifted. It is ALSO possible that something has caaaused the aftertouch sensor to move out of position and it is hitting the keys early. ANY of these conditions needs to be addressed before damage is done.

Check if the cble frm the pedal MIGHT be flexing or pulling on the keyboard case when you use it. Such movement COULD vibrate the power connector causing your problem.
Make sure you have the right power supply for the unit as one with too large a hole for the power pin would be intermittent like this.

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.
