Re: wg6100 HV problem

Is it / was it producing any high voltage?

What was the original symptom when you started?

What has been done, other than replacing R901, R907, Q900 & Q906?

Did you install or recently install a cap kit?

What are the voltages from each pin of Q900 to ground?

Thanks,
-Mark
