Hi my Tv has no sound when using some apps any suggestions? Other TVs In my house I have sound
This happened to my KD48A9. I remedied this by switching off TV via remote and then unplugging the TV from the mains. I left it for about ten minutes then put plug back in and switched TV on again with remote. Hope this works for you.
It may be also worth it to update the software if the issue remains
