Need help fixing Samsung Slimfit tx-s2783

[Alex KL-1]

When you spot a bridged land, or suspect about, you can try to test it with a DMM to see if it was really shorted. Like John said, is common to this occur (even with experienced people).

And if after this check the speaker symptom continues, try to remove the audio output IC (if it uses a IC) and power the TV on, to see if it was damaged or not.
