Well you could try moving it up close to your television. If it works there and does not work from a distance. It may need a new battery. Even if it doesn't work up close a new battery is worth a try.
If it turns out that the remote is defective it may not be worth fixing. They don't cost much. It may be cheaper just to replace it.
a tv remote used to change channels
There was buttons on the tv box itself
To change channels on an Artec digital to analog converter without a remote, use the buttons on the front panel of the device. Typically, there will be a channel up and channel down button that allows you to cycle through the available channels. If there is a menu button, you can access the channel list and select the desired channel using the navigation buttons. If your converter has a dial, you can also turn it to change channels.
Most boxes have buttons to do it the old way until you get a universal remote
To change channels on PIP (Picture-in-Picture), you can typically do so using the remote control. Look for the PIP button on the remote, then select the channel you want to view in the PIP window while the main screen shows the current channel. This allows you to switch between channels easily while still keeping an eye on your main program.
Sky remote codes are codes made up of numbers that allow you to customize your remote so you can control the volume and change your channels on the TV.
