I can't change the channel or volume. when ever I press the side panel keylock appear. Please help me to unlock my LED without my remote untill I purchase as new remote or find the lost one
The best choice I would suggest is to buy a new remote corresponding to the brand of your TV. However if you can't because the tv and/or remote is no longer available, I would suggest you to look for a an universal remote.
What is an universal remote ? It is a remote control that can be programmed to operate various brands of one or more types of consumer electronics devices. Low-end universal remotes can only control a set number of devices determined by their manufacturer, while mid- and high-end universal remotes allow the user to program in new control codes to the remote. Many remotes sold with various electronics include universal remote capabilities for other types of devices, which allows the remote to control other devices beyond the device it came with.
You can use your Android mobile as a remote if it has an ir blaster. Even if it's not inbuilt in your phone you can make it using a 3.5mm old headphone jack and an IR LED from any old remote (you may search on YouTube for that) Obviously this thing also available in the market but it would be easier to buy a new remote than searching for this in the market.
Perform a system reset; check the online documentation for your television.
On some modern smart TVs you can download an app for your phone that will pair with your tv over the wifi network and allow you to control it that way. This is true for my roku tv.
