Have TV Questions? Ask a TV Technician
You know...this is how I would handle it --
Exchange is FREE, short of shipping.
Get the correct board that matches your TV.
If the HDMI was bad on that board...you get a new board to test.
If it STILL FAILS (and it shouldn't) you're done.
If it does lose sound, the First thing on my mind would be if BOTH the DVD and CABLE box are routed into an audio amp, then OUT to the TV set.
TV's don't like that setup because the TV only wants to handshake with one unit, and when you have an cable/dvd box connected to an amp THEN to a TV set....you may get double-handshaking and it can affect the sound or the picture !
NEXT....if you don't have an AMP....and it still doesn't work...see how much time you have to RETURN that board.
Try selling it on EBAY before you have to send it back for a 20% restocking Fee.
Here's the problem that Tim or I would have....if we didn't order the board and attempted to return it at full price, they will look at our Order Requests, our PO numbers, and they will NOT MATCH.
They'll match your order, not ours.
Those are the things I would do in your situation. Exchange FIRST (and if they don't have one) EBAY second, and send it back to them as a WRONG PART.
They may let you slide if you push the wrong part issue.
Just Answer connects Techs with people that need answers. They don't hire us as employees, we are our own companies.
That is the part number on your TV's original board.

If you choose, you don't have to ACCEPT. Just Answers makes that statement.
All I want at this point is to fix the problem.
Have you checked the Samsung Support Website for any software or firmware updates ?
Do that first.
If you want reliable audio, then I would use Component Video and Audio inputs on the TV set. There is no handshaking with Component HD connections, thus you don't lose audio.
If you want to use HDMI, your choice is to use the original board number and order it from the site I listed. When you change inputs or turn one of the boxes or TV off and on, you're simply making the units handshake again.
The fact remains that BOTH the cable box and DVD has audio loss. I doubt you have TWO bad boxes....you only have ONE bad TV board.
IF you have more equipment in your home that has HDMI on it, try it with the TV's HDMI.
Most likely, I would expect all units to lose audio and prove the TV board is faulty. If you haven't updated the board, you should do that.
