I cannot find a schematic for the keyboard but with most it requires 2 leads for specific notes to play so if one were faulty for example C, E and G#, usually all the octaves of those particular notes may be affected or only the octaves up to or past where the problem was, so it is unusual for 4 notes, all I assume in the same octave to be the only ones affected.

I cannot find a schematic for the keyboard but with most it requires 2 wires for specific notes to play so if one wire was faulty it may affect several notes connected via diodes, to those two wires, for example C, E and G#.

Looking at the images you provided the only common thing that I can see that ''might'' affect the group of 4 keys you selected, is on the lead with the resistor in it as shown in the image below.
Please provide some more images showing the keys' wiring multiple to the left of the image you posted to see if all the groups of 4 keys to the left (and right?) of those highlighted also have a similar component for them as well.
If they do you may have to trace back the lead with the component I highlighted to the left of the board to check where it connects to. I think that I've shown the correct lead heading to the left on the board multiple but double check to make sure
I cannot find a schematic for the keyboard but with most it requires 2 leads for a specific note to play so if one were faulty for example usually all the octaves of that particular note may be affected or only the octaves past where the problem was, so it is unusual for 4 different notes to be affected all at once, especially in one area of the keyboard only.
