Re: UN55D6900 BN44-00428B partial led driver circuit failure
Which is "THE DIODE"? D9251? I assume bottom = anode & top = Cathode. Vdv is common to all for circuits, The high voltage may be due to lack of feedback, The circuit assumes the current through the leds is too low so it increases the voltage to compensate. Is the voltage across Q9223 source resistor high like before (2.27v)
