This TV is perfectly working other than it has no sound. Main board in question is 756TXBCB5K00903.
There is no sound from any inputs.
I did complete TV reset to clear any previous settings.
Volume is up and not muted.
TV speakers are set to on.
No external speakers or headphones are connected.
I have applied 3V to the speakers, they are good.
I have tried using external speakers and headphones with no luck. When I use headphones, I made sure that TV speakers were off. I only hear slight white noise coming from headphones.
I have also noticed that the red SPDIF-out light on the main board is not on. With most TV's there is a red light coming from optical port, regardless if anything is connect to it or not.
I have zero experience in this type of issue, any ideas what I should check?
Thanks
