Question about Samsung Televison & Video
I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV(warranty was expired ofcourse) and found four bulged capacitors. Many electronic companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices. Here are some options . 1. 1. Have it fixed by a professional 2. 2.. Dig into your TV, find PSB, Check for faultycaps. If you find some(bulged orleaking) bad caps replace the entire board 3. 3. Remove and then replace individual faultycaps. This takes some solderingskill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
Hope this helps

The volume down is likely bad on the set, this happens a lot and I will explain why and what needs to be done.
All sets with exterior controls, volume, on/off you name it behind each plastic button is a tiny switch---a push switch that when released stops.
Bad ones develop not from age but poor quality,,,,that is a momentary switch, as long as held it should function and when released stop.
Be thankful it is not the sound UP as I have seen that, Menu, you name it.
Now to the proof and the solution, Someone has to gain access to that switch under that plastic button and remove it from the small circuit board it is soldered into---2 to four solder connections and remove the switch.
A ten year old with a soldering iron can do it.
With it removed power set back and see, if problem gone you have a few choices (really no choice if it was me) order and replace the entire board with all the buttons affected or DO NOT PUT THE BAD SWITCH BACK AND just use the set with the remote.
For the technical minded first the reason a remote will not stop this is buttons on the set have priority over the remote functions and YES you can test the bad switch and find it that way---I have seen ones not being pressed that read as low as 3 thousand ohms or less and that is bad=====there should be no reading across the two pins that are for that switch itself.
Let me know if you have questions, PS none of them sell the individual parts you have to buy the same poor quality board with another set of switches on it.
