Why does the picture on my TV keep going off?
The most likely cause of the picture on your TV going off is a connection problem. Although there could be an underlying problem with the TV itself, it’s more likely that the issue is with the cables connecting the TV and other components, such as a cable box or DVD player.
If your TV has component inputs and you’re using those, make sure all the component connections are secure. If any of the cables are loose, try gently pushing them in to ensure a secure fit. If you’re using HDMI, double-check that each cable is securely connected to both the device and the TV.
You should also make sure you’re using the latest HDMI cables as older cables tend to cause intermittent connection issues. If the connections are secure and the issue persists, you may need to try an alternate source, such as an antenna or streaming device.
If you’re still experiencing problems, it’s best to take your TV to a professional repair shop to have the issue diagnosed and resolved.
How long do TVs last for?
The life expectancy of a television depends on several factors, such as the type of television, its quality, and how often it is used. An average LED/LCD TV can last up to 8 years with regular usage.

Why does my iPhone randomly get dark?
The most common cause of an iPhone randomly getting dark is due to the auto brightness feature. This feature can be found in Settings > Display & Brightness > Auto-Brightness. Auto-brightness automatically dims your iPhone’s display based on the lighting in your environment.
In other words, the darker the environment around you, the dimmer the display will be. If you find that your iPhone gets too dark too often, or if you simply don’t like it, you can turn auto-brightness off or adjust the brightness manually.
Additionally, power-saving mode can dim the overall brightness of your iPhone, even if auto-brightness is turned off. To disable power-saving mode, scroll up in Settings and press Battery. This is located next to the battery icon in the top right of the screen.
Finally, the dimming of your iPhone’s screen can be attributed to the backlight on the device (LCD) fading over time. If your device is older and you find that the display frequently gets too dark, then you may need to consider replacing the LCD.
