When the sound cuts out, even if the volume is set to zero, the speakers still wig out and make loud random noise.
I have a 46" LCD tv from 2008 (LN46A550P3F)
Audio works fine using rca plugs or component plugs, but when I try to use HDMI it will work for a few minutes, but then it will cut out and spasm every once in awhile (popping noises or random loud screech). When this happens no audio will work, soundbar tv or headphones, until the tv sits off for a little bit. I've tried settings, research, and all of that.
Im good with electronics, so if I can find the bad part I can fix it, I just don't even know what to look for. It's odd that it works fine with everything else except HDMI.
Anyone have any knowledge they could throw at me?
