Due to sharp edges on the electron gun electrodes, impurities, and other
manufacturing defects, there can be occasional arcing internal to the
CRT. Properly designed HV, deflection, and power supply circuits can
deal with these without failing but not all monitors are designed well.

There is nothing you can do about flashovers assuming your HV is not
excessive (see the section: Excessive high
voltage. If these persist and/or become more frequent, a new
CRT or new TV will be needed.
