Hi

If unplugging the CRT base board from the CRT, I was always taught it's best to first discharge the CRT final anode to the CRT's aquadag braided wire by using a heavily insulated wire such as EHT cable. The shorting lead should be kept in place as the anode can often regain charge. This operation is simple for those with experience in the TV repair business but would not be recommended to anyone without the experience to do this for obvious reasons.

It would be best to leave this repair to someone with the relevant experience or at least be shown what's involved to make you aware of the safety hazards involved. Sorry to sound dismissive but your safety is paramount.

Regards
Symon.
