Vizio M550NV with no sound

Posted by on 8/2/2018 to LCD & LED Televisions Tips
This Vizio tv model M550NV using main board part number 3655-0102-0150 / 3655-0102-0395 had no audio output from component, HDMI, Video and tuner. By reflowing the BGA micro located inside the aluminum heat sink / cover restored the audio problem on all of the inputs. Replacing the eprom will not solve that issue.
