remove the anode cap.   Short between anode and coated earth ground strap of CRT.
NOTE: After removing the anode cap, short circuit the anode of the picture tube and the anode cap to either the metal chassis, CRT shield, or carbon 
painted on the CRT. 

1.  Do not use sharp objects which may cause damage to the surface of the

terminal to protrude and damage the rubber.

cap fi rmly in the direction indicated
by arrow   b .
