It’s a nightmare scenario that borders on reality fracturing. You go home from a long day. You sit down to watch something, calm down from the day, and relax for the few forsaken moments you can and the TV isn’t working.
Now, instead of relaxing for the only section of the day you get to just be and not do, you have to scramble to fix some nonsense TV problems. With modern flat screens, LEDs. LCDs, plasma, and everything in between being more computer than machine, this is a daunting task.
A task that might have you deciding to toss the old set and get a new one rather than spend even an hour frustrating yourself. Not everyone has a propensity for breaking things with overt physical force when they don’t work as intended.
That said, for the few of you out there itching for a reason to smash and replace, here are a few common TV problems and their fixes.
Modern TV Problems
The following elaborate on the what and the why of several common TV issues. These are centered around fixing issues with the television proper. If there is a problem with the reception from a cable service, satellite, or antenna, you can learn more about those issues.
1. Black Disconformity
The issue of a lack of black uniformity on a TV underlies most issues with picture quality. Unlike a color printer using all of the colors to create black text, LEDs can’t create black. Instead, they project light onto a backlighting sheet.
If that sheet is mounted improperly or becomes gapped from damage, the lights behind bleed through. This means that the black components of the image become not so.
The fix to these issues is to loosen and tighten the screws holding the TV together. Massaging the screen with a damp cloth also helps unstick diodes that become affixed to the screen.
2. No Picture
The most common noticeable issue is a lack of picture.
No picture whatsoever means a lack of power inside the box. No power means plug it in or replace the set.
A blip or scroll indicating ‘input’, ‘source’, or ‘HDMI #’ means the system is trying to pick up a signal from the wrong cable.
The quickest fix is simply to scroll through the connected sources with the remote or on-set button until a picture appears.
3. Green Tint
Fixing the tint on a television isn’t always easy because of the subjective nature of color settings. At one point, the tint setting on a TV controlled everything in picture tone, now you have color warmth in addition to color levels, contrast, and brightness.
Generally speaking, adjusting the television back to a default setting will show you if the problem is with the screen or the internals.
If the screen is still green after a default setting, the actual screen in front of the light-emitting diodes may have discolored. At one point, this was caused by magnetic fields, but flat screens aren’t affected by magnets.
If you have the TV directly facing a window and live in a sunny place, the screen can melt and discolor over time. If this is the case, replacing the screen is necessary. With repairs often costing more than a new device, this might be a time to get a new TV.
4. Vertical Hold
Actually, this is now called anti-aliasing. Flatscreen TVs don’t have vertical hold so much as they have an internal processor that projects lines of light on the screen.
If the anti-aliasing setting is wrong, the timing to refresh the lines gets off. This leads to lines being projected where they don’t belong or holding when they should go away.
Adjust this setting through the picture menu.
5. Video/Audio Mismatch
This problem occurs when the picture frame rate and the audio refresh rate get out of synch. It turns everything you watch into a foreign film where the mouths are moving and the words seem to be coming from somewhere else.
Adjust the audio delay setting through the ‘audio’ menu. This is shown in +/- Hz. Adjust one notch at a time until the two elements match up.
The other common audio problem is echo. This comes from an imbalance between speaker systems. If you experience this from the onboard speakers, it’s a mechanical problem requiring repair or replacement.
If this happens when you have an external sound system or soundbar, the issue is that the two devices shouldn’t run together. Turn off the TV speakers through the ‘audio’ menu
Pixelation is a problem with the signal not telling the internal diodes to fire. This is usually an issue with the signal to the TV being disrupted.
For cable and satellite, confirm the services aren’t experiencing issues. For SmartTVs check, your Internet isn’t bogged down.
If you experience this with physical media such as a BlueRay player, the problem is the TV is dying and needs to be repaired/replaced.
8. Remote Not Responding
Pairing a remote is a complicated task. Changing batteries is easy.
Start with a battery change. IF that doesn’t work, follow the instructions of the manufacturer to pair the remote.
Alternatively, for SmartTVs, you can get a phone app that connects to the TV and lets you run things from there.
9. Captioning On/Off
It doesn’t matter if you prefer captioning to be on or off, if it isn’t the way you want it, that means fixing your TV.
Most of the time this is controlled from a setting within the ‘picture’ menu. Remotes also have designated CC (closed captioning) buttons. Check if the setting is default set for on/off and adjust accordingly.
10. Picture Size
Not all flatscreens are created equally, nor are all programs filmed equally. The aspect ratios 16:9 and 4:3 change how an image is displayed.
Most sets automatically change the picture from a native designation to your preferred. If the image is all wrong, you can change the aspect ratio through the ‘picture’ menu.

The solution to most TV problems is to either adjust something in the setting or replace the TV. That’s the price of modern living, it either works as intended or you need a new one. Progress.
