Set needs some basic troubleshooting performed by a qualified technician in
order to find the problem and repair it. With the information provided, I

Probably defective power, deflection assembly, you will probably find a
shorted diode if the power supply circuit. Suggestion is to replace the
whole assembly. other item may be the hv distribution block also.
