Volume does not work on television - Samsung TV Remote Control

Check the batteries.
If you have a digital camera, camcorder or camera phone, turn it on and point the remote at the camera lens. Press the volume buttons on the remote. You should see a flash on the camera lcd screen. If not the buttons on the remote are not working.
Check the buttons on the side/top of the tv to make sure the tv volume is working.
If the remote is dead, sometimes doing the following steps may restore it.
Step 1- Pull the batteries out of the remote and leave them out until Step 4.
Step 2- Press and release each and every button one at a time on the remote control until every button has been pressed and released at least once!
Step 3- If your remote has slide switches, you must move the switch to each position then repeat the button pushing in Step 2.
(When you're done, be sure to put the slide switch in the correct position to operate the unit the remote came with!)
Step 4- Put the batteries back into the remote, being very careful to install them correctly.
New batteries should be used if you're not sure about the old ones.
Step 5- Try the remote.
