Does anyone has a schematic for the mainboard BN41-01181A?
This TV works but has no sound over HDMI. The PC sound input works though. Can't test the other audio inputs, I don't have an AV video source.
Also the buttons on the side , especially volume up , down and menu, source do not always do what they are supposed to do but I don't know if this is linked to the other problem , maybe not. They use a resistive ladder it seems to determine which button was pressed. The voltages aren't always stable when the button is pressed, maybe just corroded contacts inside the buttons, gonna clean them with contact spray or replace them.
I have clean 5V coming from the power supply board, no excessive ripple... I really think I need a schematic for this board for the sound problem.
It's BN41-01181A, BN96-11408, bn97-03889.
Thanks!
