The remote works to cut on & off, turn up & down volume, but not change channels. Is there a reset button?

The buttons on most remotes are the soft rubber type. The conductive film under the rubber is very thin and gets damaged very easily when pressed really hard. If you can still change the volume using the buttons on the TV and one or more buttons on the remote works and not works at times then it a bad button on the remote. Unfortunately you can't just change a single button as it's mounted on a pad. The whole remote needs changing. Check with TV vendor or look for a replacement on Amazon.com. Try to get the exact model and avoid using a universal remote. Yes, they work for basic functions but won't have the specials lik PIP (picture in picture).
* Oh, if your using a cable box. You may be able to program the cable remote for use with your TV (at least to control power and volume) Check you cable channel for setting up the remote. (They usually have a dedicated instruction channel.)

Try to reprogram the remote

Hi, well you can do everything from the axtual TV itself, have a look on the TV you will find a setof buttons/keys. these allow you to controll almost everything that the remote can do.
here you can change channel change volume etc.
The buttons usually there are 6- 7 marked On/Off, Channel up/down, Volume Up/Down, Enter/OK & Menu. Now pressing these will bring up the onscreen display and you can adjust what you wish.
Now with the remote, it's probably best to obtain a new one..
Sometimes disassembly may fix it, but it sounds like it has a bad problem.
To ensure it doesn't interfere remove the batteries.

OK, YES you CAN turn on the TV without the remote, in fact you can do nearly everything that can be done on your remote, on the TV itself, NOW look, CAREFULLY around the edged or sides of your set, you will find there are "Buttons" usually there are 6 - 7 Buttons, if you look carefully at them you will see they are marked, usually with a Volume Up & Down, word, or symbol, A Channel Up & Down, buttons a Menu, an Enter, and an ON/OFF button, & sometimes others. Now To turn on, Press and hold the Power button, the TV will Turn ON, you can change Channels, with the Channels, and Volume, with the Volume ones. The Menu button, will allow selection to all the other sub menus and settings. IF you need to get a remote, Please, get an original, it may be more hassle, it may take longer to get, it maybe costs more... BUT IT WILL WORK. Universal remotes, well, read through a few posts dealing with them, and you will see what I mean. IF you MUST get one, absolutely ensure that it performs every function the original one did, or you can have many headaches.

technically we call it debouncing it causes due to the faulty microprocessor in remote also it can happen due to faulty carbon contacts of remote below buttons.the solution to this is to replace remote but before that do one thing 70% THIS WORKS open ur remote then take a dry cloth & clean the surface below buttons if u r lucky then remote will be OK

check to be sure your remote is sending IR signal, with
a smart phone camera hold remote IR eye in front of camera and click any buttons on remote, you should see
a light coming from IR eye. If no light emitting, remote needs to be replaced.

you can always use the button on your Tv itself.

ie menu = Menu
Channel up/down = take you up and down
volume = goes left and right.

follow these steps

Menu,
channel down button to CHANNEL
press the volume button along
channel down button to AUTO STORE
press the volume button to Start the scan.

right now you have your telly tuned in. What you could do it get an old sky remote off a friend/ neighbour. or buy from argos etc ( a lot cheaper then getting a replacement samsung one)

press the following buttons on the sky remote to program it to work with your samsung tv.

TV,
RED + SELECT
TV.
0060

try the volume if this works press SELECT to save this code if it doesnt press Tv then try the volume again. repeat this step until the volume works your telly. once it doest dont forget to press the SELECT button to save.

Now you will be able to change your volume use the number keys. if you also press the HELP button on the sky remote this will also change your AV / SOURCE I hope this post helps you out. When it does please leave a thumbs up for me Please
