The PSU in my Sanyo Beta VTC5000 has stopped working. I am testing all 16 Diodes on the 2 Cct. Boards: PW-1 (2 Zeners) & PW-2 (5 Zeners and 9 ordinary Diodes.) Using my Multimeter UNI-T model UT-61E (which has a Diode select button on the Ohms range). Should the meter read any v. when connected Pos. - Neg. across any Diode? When connected Neg.- Pos. across all Diodes they read about 0.7v. but when connected Pos. - Neg.4 Diodes read up to 1.8v. the rest shew OL. Is this a valid test method? . The Cct.diag. is available from: www.freeservicemanuals.com Michael of Studio1.
