33 No sound from Left side- Intermittent sound from right side
Ok, I bought a soundbar similar to a Vizio Soundbar from eBay and after my friend heard the soundbar he went ahead and ordered one from eBay himself. He wasn't as lucky as me and his soundbar has no sound from the left side and the right side goes off after some use. He brought this in to me since I'm a little better than he is at this, but I'm by no means an electronics expert. Upon close inspection of the components and extensive inspection of the board and it's capacitors, all look good, except for the fact that there's a 14 Pin and 4 Pin dock on the board with no wires or connectors attached to them. There are no loose wires or any possible connections left on the device. I'm assuming these 2 docks might go together. Is there any way to find out if these go together, or whats missing for that matter? Please Help. Can't find any documentation online.

I'm not good with these foto editing tools, but if you look closely you'll see the two rectangles marking the connectors. ABCellars, where are you? ;)

Have you opened yours to compare? It sounds like a cap problem tho.. Try tracing speaker wires back to board and concentrate on caps nearest would be my start. Oldturkey prob has the manual, no idea where he gets them... Like a magician! Try dropping ab or ot03 an email.. Always been super quick replies. Best of luck, jen

Just thinking the 4 pin reminds me of speaker connection off tv set.. L,R speakers + ground? Are you missing connector from left?

Majesty, do you have more info on the sound bar? Model number etc. could be helpful in getting more info on it, there are a couple of different ones out there. I am with pollytintop on that one; the unoccupied connectors do not necessarily pertain to your issue. Those may be expansion/test/diagnostic plugs. Check your wiring, traces and caps. check on your IC's and if you can gt as a couple numbers of the IC chips itself. I was wondering if you are having issues with bad soldering, loose chips etc. If you have an IR thermometer, try to see what the temp of the chips is during operation.
