Need to see the OTHER side of the board. Those sparkgaps I am familiar

look like a small ceramic disk capacitor with a slit cut into the edge
perpendicular to the disk.

They might be INSIDE the body of the socket (white plastic thing on the
board you are holding).

There are no parts except a few SMD capacitors, as far as I can see. And
there
is nothing whatsoever in the white body (I desoldered it to have a look.

As posted, the spark gaps may be physically inside the crt socket assembly
itself. The odds of disassembly and proper reassembly of most of these
sockets is actually relatively low. It may be done with proper tools and
techniques.
What you may find is that due to arcing at the gaps or external contaminates
that the surfaces may have become carbonized and pitted. At that point it
may be best to look for a new crt socket and just replace it.
