6 blinking lights, SONY logo comes up for a sec and then off. I checked all diodes on power supply and found D6201 and D6202 which are side by side with continuity.

Re: Kdl75w850c
If you really want to test them, lift one leg off the board and retest, BTW, they are connected in parallel.
If you check the DCV between Cathode and chassis ground, you should see either 3.3V or 5V which are typical Standby Voltage for TV.Last edited by budm; 08-17-2020, 08:02 PM.Never stop learning

Re: Kdl75w850c
The end side with bar is Cathode, another end is Anode, meter should only beep when Black probe on Cathode Red probe on Anode, the meter will display the Forward Voltage of the Diode, when you reverse the leads then you should see 'OL'.Never stop learning
