The tv itself makes a high pitched sound when I turn it on, but there is no audio to the tv. I checked all the cords, mute button is off, I plugged in other devices and a surround sound system and still no luck. I'm wondering what the issue could possibly be, as i'd like to try to repair it myself if I can
