SUBJECT : Improvement of highvoltage output TR failure
Background : If you can find any Q504(MJW16212) failure among the set returned to SVC center.
(Symptom) Firstly check the manufacturing date or serial no. and add the parts below.
Cause : We deleted sunbber circuit in Q504 base part to improve noise problem.
as to this, sometime, the high voltage TR(Q504), fails in 106KHz/85Hz mode
for the high temperature in short time.
Solution : Add to capacitor and resistor.
