Purity issues on a HP MX70 Monitor

[zeno]

First confirm the built in DGS is working. Measure AC amps at COLD
start. Should swing up to 2 amps +- then drop to apx .75 amps. Analogue meter
is best for this. If it dont look for cold joints on PS module.
Next be sure no yoke shims or little correction magnets have fallen off.
Also look at the CRT neck magnets. Usually after set-up they paint white
stuff on them to hold them. Look for evidence they moved.

Thats the general idea. BTW Purity is done with only one color operating.
Usually green on in-line jugs.

best 73 from the colonies !
