Unplug and leave it unplugged for a while and then make sure the plug is nice and secure on both ends and try again

The wire from pin 1 or 7 of CN1 on the GHL88L (left end) circuit board is open where it goes to the middle circuit board. This could be a bad cable, improperly seated cable connector, or a crack in the circuit board(s) connecting to these wires. These are the common matrix wires associated with only the C# and G keys for the left 1/3 of the keys. If more than 1/3 is dead, then the problem is likely on the middle board GHL88M that connects to the mating cable to the CN1 connector.
There are two wires dedicated to the keys for the two contacts that are used to measure velocity of the key strokes. There is a mechanical position between closing the contacts and the time is measured by the processor as velocity.
If you are the least bit worried about working on electronics you best have a service person do the repair. The keyboard has to be lifted out after removing the top and disconnecting other cables.

yes - use two RCA cables from the left and right audio output and connect it to the aux audio RCA inputs of an amplifier or receiver.

Check if you MIGHT be in a "guide" or learning mode. Some Yamaha synths have a mode that will play and then wait for you to hit the right key before moving on. If this is not the problem, a fix is not DIY and will require repair. I assume you are NOT using MIDI as in that case it is called "dreaded MIDI drone" and is due to data looping back into the unit which is an external fault.
