A few years ago, this question would have been easy to answer. Remote controls were once fairly simple devices. The circuitry inside a television was generally an "add on" to the television. Often, manufacturers used remote control circuits developed and produced by integrated circuit manufacturers so they used standard protocols.
Modern televisions are very different. The remote control is far more complex with a vast array of buttons. Every button generates a string of pulses that is unique and manufacturers normally use a coding system that is not published. To make it harder, the remote control circuitry inside the television is now part of the control micro-processor that resides in almost all televisions. The information needed to build a new remote control can be very difficult to obtain. Most manufacturers will not release the information so a would be constructor will have no help.
On a more positive note, there are various web resources that offer information on remote control codes. The information is often in the form of a file that specifies the string of pulses used by each of the buttons. Although much of the information is accurate, it is no small task to convert the file into something meaningful. It can be equally hard to construct a remote control that uses the information.
Theoretically it is possible to use the coding information and program a small processor to send out the pulse strings. The PIC by Microchip is one of several components that would be suitable. There is a significant amount of programming to be done as well as some electronic design to turn the PIC output into an infra-red signal. Adding a large number of buttons demands some electronics knowledge and experience too.
For most people, the steps to make a remote control are too numerous and complex to be worthwhile. The end result will be no better than the manufacturer's original part and will probably be far more expensive.
If, despite the warning, you decide to go ahead with it, you will need a certain amount of luck and a great deal of persistence. Don't be afraid to ask for help in a forum or two. There are people who work in the field and they can be very helpful indeed.
To program a One for All remote to be used on a Symphonic television, turn on the television manually. Then, hold down the television button on the remote, and push the power button until the television shuts off.
To program a Charter remote to an LG TV, first turn on your TV. Then, press and hold the "TV" button on the remote until it lights up, then release the button. Next, press and hold the "Setup" button until the TV button blinks and then stays on, then enter the code for LG TVs (you can find the code in the remote's manual). Finally, press the "TV" button again to save the code, and test the remote by trying to control the volume or power on the TV.
To program a RCV remote with a Magnavox TV box, first, turn on the TV. Then, press and hold the "TV" button on the RCV remote until the LED lights up and then release it. Next, press and hold the "Setup" button until the LED blinks and then stays on. Enter the code for your Magnavox TV (found in the remote's manual), and if the LED turns off, the programming is successful. Test the remote by trying to control the TV.
To program your Comcast remote for an Auria TV, first, turn on your TV. Then, press and hold the "Setup" button on your remote until the red light stays on, then release the button. Next, press and enter the code for Auria TVs, which can be found in the Comcast remote code list (usually a 3 or 4-digit number). Finally, press the "TV" button to save the code, and test the remote to ensure it controls the TV functions.
To program your Viewsat remote control to your LG TV, first, turn on your LG TV. Then, press and hold the "TV" button on the Viewsat remote until it blinks and stays on. Next, press the "Power" button repeatedly until the TV turns off, then press the "Enter" button to save the setting. Finally, test the remote functions to ensure it controls the TV properly.
To program a Quemex TV remote to a CCE brand television, first, turn on your CCE TV. Then, press and hold the "TV" button on the remote until it lights up, and then release it. Next, enter the code for CCE TVs, which you can find in the remote's user manual or online; the TV button will blink and turn off if the code is accepted. Finally, test the remote by trying to change the channel or adjust the volume to ensure it is working properly.
To hook up a Sony KP-53V45 TV to a Max remote, first ensure the TV is powered on. Then, locate the "Code Search" button on the Max remote and press it until the indicator light stays on. Next, enter the TV code for Sony (usually found in the remote's manual or online) and press the "Enter" button. Finally, test the remote functions to ensure proper setup.
To program a Comcast remote to a Vizio TV, first, turn on the TV. Then, press and hold the "TV" button on the remote until the LED light changes from red to green, then release the button. Next, press and hold the "Setup" button until the LED turns green again, then release it. Finally, enter the code for Vizio TVs, which can typically be found in the remote's user manual or online; if entered correctly, the LED will turn off. Test the remote by trying to control the TV volume or power.
To set up a cable remote to operate silo TVs, first, ensure the TV is powered on. Then, press and hold the "Setup" button on the remote until the red indicator stays on, then release the button. Next, enter the TV's brand code using the number buttons; the red indicator will turn off if the code is accepted. Finally, test the remote by trying to change the channel or adjust the volume on the TV.

A new remote will usually work with your TV, as long as it a newer model and your remote carries the TV remote code.
When a Charter TV remote breaks the company will replace the remote. In most cases, there will be no charge to replace the remote.
