Summary
Due to its regular use, the power button on a TV remote control is typically the first button to be identified as failing. This document describes some troubleshooting tips.
Diagnosing Problems
If the remote is working when pointed in just the right direction, or when moved closer to the TV, then the problem may be caused by low battery power. However, if some buttons work fine and others do not, the remote may be getting worn out.
Low Battery Power
The most common problem with a poorly functioning TV remote is low battery power. Try replacing the batteries with new ones. Or, if your remote is rechargeable, make sure it is charged.
Here are some considerations for removable / replaceable batteries:
- Alkaline — The most common type of battery used in a TV remote would be alkaline of AAA or AA size. These last a long time, and provide the proper required voltage.
- Lithium — A longer life battery is lithium and these are available in the AAA or AA size. They may cost twice as much as alkaline, but have the convenience of reducing the frequency of replacing them and less electronic waste than alkaline over time.
- Rechargeable — Using rechargeable batteries can help reduce electronic waste. The typical battery size for a TV remote is AAA although some use the AA size. Finding AAA rechargeable batteries and chargers is challenging but worth it. It’s possible to purchase the batteries with a charger, or if you already have a charger, just the batteries. Keep in mind that some electronic devices, like TV remotes, may not work with rechargeable batteries because the battery voltage is usually 1.2 volts rather than 1.5 volts. So the typical two batteries for a remote will be 2.4 total volts rather than 3 volts. Even with a fresh charge they may be considered to have a low power level. Some rechargeable batteries are available with 1.5 volt output. [Example] Here are some Amazon search results for various types of rechargeable batteries.
Failing Remote Buttons
Over time, commonly used remote buttons can become worn and the contact surface for the button becomes oxidized or otherwise worn out. If you find that some of the remote buttons are working an others are not, it may be a worn out remote.
Try purchasing a universal remote as a replacement. Some universal remotes have better dispersion of the infrared signal and/or have a stronger signal. So, they tend to work better, even as the battery power is diminished later. They are more efficient.
A universal remote may have better button design for more reliable contacts and switch function.
A good example is the Best Buy Insignia remote shown below. [Learn More]
