Had a spare mainboard and speakers from another set, once that didn't work I ordered a repair kit from SJ to try and fix this TV. I made sure to check that the TV speakers are set to On in the menu. Either I have defective parts or bad speakers which is unlikely. So far I tried 3 mainboards and two speaker sets, can it be something related to the panel board? Testing sound using the HDMI and the built in Youtube app. I don't come across many sound issues, but I expected to be only the mainboard. Am I not looking at the right areas?

Have you checked if you have +12V_A from the power supply, I believe that is the 12 volts for the audio outputComment
