TV Screen Looks Darker Than Usual? Here Are Some Simple Solutions






When your TV screen looks darker than usual, there are several possible causes for this issue. Your TV might be malfunctioning and need to be repaired or replaced, but it also could simply be a matter of adjusting how bright the screen looks. In either case, you should take steps to resolve any issues as soon as possible to prevent them from getting worse.


Here are some common solutions you can try:


Make sure you look at your setting options when encountering a dark tv screen.


The first thing you should do is check your settings. Some settings might have been changed, so it's always a good idea to get back to square one.


  • First, check your picture settings. The contrast, brightness, and sharpness of a TV set are adjustable through a variety of menus on the remote control; check these out to ensure they're all set properly. Most modern TVs will have separate levels for each of these elements as well as an overall "contrast" setting for the entire screen (which usually has its own way of being adjusted). If you need some help figuring out what all those buttons do, YouTube has some great step-by-step videos if you want to see before/after examples.


  • Next up: check out your backlight level—it's often set at 100% by default with no option for adjustment unless this is changed manually in the user menu settings (and even then it may not be adjustable). This makes sense since without enough light shining through your television screen could get so dark as to be almost completely unviewable—but if there's too much light coming through it can wash out colors and distort images onscreen into something that looks more like an impressionist painting than anything else! If this sounds familiar then lower those backlights until things start looking right again.


  • Finally, check the Picture Mode setting. Picture modes alter numerous settings at once. Nowadays, the majority of TVs include picture modes. The "Cinema" option, for example, will make the image appear a little darker than usual. To access your TV’s picture mode settings, first press the home button on your remote. This will bring you to the main menu of your TV. Now, use your arrow keys to navigate to the Picture option in this menu and press OK or Enter on your remote.


Check the Light Sensor


The light sensor is a small, round device that sits on the rear of your television. The sensor measures how much light is hitting the screen and adjusts the brightness accordingly. If it isn’t working properly, you will notice that your TV is darker than usual even when it is just in a room with normal lighting levels, such as those found in an office or living room.


To check whether your TV’s light sensor needs cleaning or replacing:


  • Unplug your TV from its power source and disconnect any other cords connected to it (such as HDMI cables).


  • Remove any covers around where you found the light sensor on your TV; if there are screws holding them in place, use a Phillips head screwdriver to loosen them before lifting off each cover section by section.


  • Look at what's left of your TV's back panel after removing all existing covers; you should see two holes near where the cable enters into the main body of this device—one larger than another—and a round black object sitting between them.


  • If there's anything blocking either hole (e.g., dust), remove these obstructions with tweezers or cotton swabs dipped in rubbing alcohol until both holes are clear enough for light from behind when viewing from an angle directly over top.


  • Next look for any cracks or chips on top around either hole where dust might have gotten caught underneath.


  • If so replace damaged components now before proceeding further! 


Is There a Power Surge?


If you have a brand new TV and the screen is dark, it could be that your high voltage has caused a power surge. In this case, check to see if your outlet is working properly. If it's fine, then check to see if the fuse in your TV needs replacing. If you find that the fuse is blown and needs replacing, do so with as many replacement fuses as needed until one works well enough for you to use your TV again (and then buy more fuses for future use).


Next, try resetting your power surge protector and see if that helps remedy any problems you're having with lighting levels and intensity in general.


You may think that powering up your TV after a power surge is a good idea, but it's actually not. Your TV could be damaged if you do this. Power surges can also lead to other problems like damage to your electronics and appliances in general, so it's best to take precautions.


  • Don't use the television right after a power surge—wait at least half an hour before turning on your TV again
  • Don't use a surge protector with multiple outlets: These are dangerous even when they work correctly; if one of the outlets' malfunctions or fails entirely (and most will), then all of them will fail.


Restore Factory Setting


If those steps don’t help alleviate any issues at all, then go ahead and restore factory settings on your television set (or whatever device you’re watching). Once everything has been restored, check around again for other possible solutions before giving up hope!


Check HDMI Cable


If you're using an HDMI port that's not working well or has been damaged, it could result in a darker-than-usual screen.


If you switch the cable or change devices and the TV is at a regular brightness, this is the case.


Why Is Your TV Dark On One Side/Bottom?


The issue is a little more serious if your TV is just dark on one side. A TV does not have any settings that could cause some sections to appear darker than others. This indicates that a hardware issue is probably present.


If you're lucky, the HDMI cable will be the cause of the issue. After you swap that out, everything ought to work perfectly once more. If you're less fortunate, there may be an issue with the TV itself. This might be the result of a bad board, bad backlights, etc. This problem will be more difficult and expensive to tackle in both scenarios. You may have to consider getting a new one.
