Good evening all
I could do with some help if you don't mind. I've pickup up a LG 55EC930V OLED curved set that clicks on with no display or sound then off after 3 seconds. The LG bezel logo is on for the 3 seconds then fades out. The previous owner said the screen went white then powered off and he assured me there was no screen damage. I have tried a replacement main board and there's no change. So, before I buy a TCON board,
Is there a way to check that the main board isn't in some kind of lock-out mode?
Am I right in thinking DRV-ON is the signal back from the main board and should be 3.5v?
Can I manually apply 3.5v to DRV-ON? What should I expect?
During the 3 seconds of activity the PS is outputting the following:
3.5v = 3.54v
12v = 11.8v
24v = 25v
PWR-ON = 3.4v
DPC = 0
DRV-ON = 0.08v
Thanks for your help
