Backlights intermittantly strobe at a fast rate. It flickers fast every time it is turned on or off, other that that it is not inconsistant and intermittant.
The set has a BN44-00343B P.S. The board that connect to the backlights look fine. I am assuming that the PS voltage from CN801 is fluctuating.
My old Pomona 40k HV probe does not read the voltage when backlights are light up. What is best a to read the HV from inverters. The 40K stand alone probes dont seem to be accurate on the low end . The analog meter maybe better to dhow fluctuations if not too fast. What are the better probes reasonably priced to connect to a Fluke 87 Multimeter? Suggestions?
The Backlight Driver board dont show any damage. I dont think its a backlight dim pin from M.B. to P.S. voltage? I am almost postitive it the
P.S./ Inverter.
Thanks
