A quick go - NO go testing of the high voltage sections would be to run the back of your hand near front of the tube. Of the hairs on the back of your hand stand up due to the static then you can assume HV is present. No static on the front of the CRT it can be assumed that the HV is missing.
Power needs to be on of course but the case covers can be in pace for this test. To increase the sensitivity of the test the implosion shield can be temporarily removed to expose the front glass.

Hello David, thank you for your response. I did all the tests that Mark advised me below but without success. I think that the problem is with the HV module. Unfortunately, I do not have the equipment to measure voltages above 1000 v. Is there another way to check the HV module and the tube ? Thanks in advance for your reponse, PS
