Power but no sound on tv on my 55 inch
I have a 55 inch led hdmi digital TV and the volume turns down by its self , and remote doesn't work when the TV does this . I tried to use the buttons on the tv, but that did not work . I also tired unplugging and holding the power button on tv . That seemed to work temporarily, but then it happened again . What can I do to fix it ? Please help. Thank you.
The model number is fw50d36f.
