1. Supply a White Pattern Signal to the Video Input Jack.
2. Confirm that the purity is still correct.
3. If the purity is not acceptable, readjust the purity.
4. (For model with 20 inch CRT)
If the convergence error is more than 1.5 mm (0.06 inch) from the
green dot at each corner, adjust the convergence at that corner
with a Permalloy Magnetic Strip. Insert a permalloy strip into the
gap between the Deflection Yoke and the CRT along a diagonal
line of the CRT bell. Adjust it for the best possible convergence.
Use one Permalloy Magnetic Strip in each corner if necessary.
