Re: 60pb690v ysus repeatedly burn igbt
Are you tightening the Floating GND lugs firmly?
Yes, very tight.
Are there shorts on the Upper and Lower Buffers?
Upper buffer looks short at diodes an capacitors when I connect ysus.
I checked all the components on the upper buffer and all are in the parameters.
Lower buffer checked and all the diodes and capacitors to be shorted, removed from pcb indicates correctly.
Is Vs what it is supposed to be according to the Panel sticker?
Va and Vs from xsus are ok.

I tested buffer boards after changing the capacitor and everything is ok.
The voltages given by zsus are...

Re: Lg 50pj550 no STBY light
Hi again, Please i need some advice.
I connected the board as in the training manual with 2 bulbs of 100 watts between the vs and the ground. I made straps between rl-on / stby and m-on / stby with a 100 ohm resistor and between gnd and autognd. the bulbs illuminate for a few seconds and burn again zd 301.

Re: Lg 50pj550 no STBY light
Update:
I found c311 burnt. I removed the capacitor and now without it I have normal standby voltages but the red LED is off . where can i find the list of smd capacitors values? on the schematic are not noted.
I need to know the value of c311 and c310.
P813 In stby: relay click just one time (3 sounds normal i think)
17v pin 0v
5.1v pin 0.69v
er det pin 1.69/1.72v
stby pin 3.50v
ac det pin 0v
