1. Physical Screen Cracks and Shattered Displays
What It Looks Like
Physical cracks are perhaps the most obvious type of TV screen damage. They appear as visible lines, spider web patterns, or shattered areas on your screen. The damage may be localized to one area or spread across the entire display. You might notice black spots, discoloration, or ink-like bleeding around the crack, especially on LCD and LED screens.
Common Causes
- Impact from thrown objects (toys, remote controls, gaming controllers)
- Children accidentally hitting the screen
- TV falling or tipping over
- Improper mounting or installation
- Pressure applied during cleaning or moving
- Manufacturing defects in rare cases
Affects All Brands
Physical cracks can occur on any television brand including Samsung, LG, Sony, Panasonic, Hisense, TCL, Sharp, Toshiba, Philips, and Skyworth. Modern thin screens with minimal bezels are particularly vulnerable to impact damage.
Can It Be Repaired?
Unfortunately, cracked or shattered screens typically cannot be repaired economically. In most cases, the cost of screen replacement approaches or exceeds the price of a new television. However, it’s worth getting a professional assessment, especially for high-end models or larger screens where replacement might be justified.
2. Dead Pixels and Stuck Pixels
What It Looks Like
Dead pixels appear as tiny black dots on your screen that don’t display any color, while stuck pixels remain permanently lit in one color (red, green, blue, or white). You’re most likely to notice them when displaying solid colors or during dark scenes. A single dead pixel might seem insignificant, but clusters of dead pixels can be distracting.
Common Causes
- Manufacturing defects
- Electrical issues or power surges
- Age and wear of the display panel
- Overheating
- Physical pressure on specific areas of the screen
Affects All Brands
Dead and stuck pixels can occur on LCD, LED, OLED, and QLED displays from any manufacturer. Even premium brands like Sony, Samsung, and LG are not immune, though quality control standards vary by manufacturer.
Can It Be Repaired?
Stuck pixels can sometimes be fixed using pixel-fixing software that rapidly cycles colors, potentially unsticking the pixel. Dead pixels, however, are permanent hardware failures. Most manufacturers have pixel policies defining acceptable numbers of dead pixels before warranty replacement. Professional assessment can determine if your issue qualifies for repair or replacement.
3. Backlight Bleeding and Clouding
What It Looks Like
Backlight bleeding appears as bright spots or patches of light that are visible around the edges or corners of your screen, particularly noticeable during dark scenes or when displaying black images. Clouding is similar but appears as uneven brightness across the screen, creating a patchy or cloudy appearance in darker content.
Common Causes
- Manufacturing variations in panel assembly
- Uneven pressure on the display panel
- Temperature fluctuations causing expansion
- Improper mounting putting pressure on the frame
- Age-related deterioration of backlight components
- Damaged or misaligned LED backlights
Affects All Brands
This issue primarily affects LCD and LED TVs across all brands, including Samsung, LG, Sony, TCL, Hisense, and others. OLED TVs don’t have backlights, so they don’t experience this specific issue, though they can have other uniformity problems.
Can It Be Repaired?
Mild backlight bleeding is often considered within acceptable tolerances. However, severe cases may be repairable by adjusting the panel assembly or replacing backlight components. Professional technicians can assess whether repair is possible or if warranty replacement is appropriate for newer units.
4. Vertical or Horizontal Lines on Screen
What It Looks Like
Lines on your TV screen can appear as thin or thick vertical or horizontal stripes in various colors (white, black, red, green, blue, or multicolored). These lines may be constant or intermittent, affecting the entire length or height of the screen.
Common Causes
- Loose or damaged internal cable connections (T-CON board cables)
- Faulty T-CON (Timing Control) board
- Problems with the panel itself
- Graphics processing issues on the main board
- Electrical interference or power issues
- Physical damage from impact or pressure
Affects All Brands
Line issues can affect any TV brand and model, from budget to premium. The specific cause often varies between LCD/LED models (Samsung, Sony, LG, TCL) and OLED displays (LG, Sony, Panasonic).
Can It Be Repaired?
Yes, in many cases! If the issue is caused by loose connections or a faulty T-CON board, professional technicians can often repair this by reconnecting cables or replacing the board. Panel-related line issues are more serious and may require screen replacement.
5. Screen Burn-In (Image Retention)
What It Looks Like
Screen burn-in appears as ghost images or permanent marks that remain visible even when displaying different content. You might notice faint outlines of channel logos, news tickers, gaming HUDs, or other static images that were displayed for extended periods.
Common Causes
- Displaying static images for prolonged periods
- Watching channels with permanent logos
- Extended gaming sessions with static HUD elements
- High brightness and contrast settings
- Aging OLED panels (most susceptible)
- Screensavers or menus left on for hours
Affects All Brands
While any display can experience temporary image retention, permanent burn-in is most common on OLED TVs (LG, Sony, Panasonic OLED models). Plasma TVs (older technology) were also highly susceptible. Modern LCD and LED TVs are generally resistant to permanent burn-in.
Can It Be Repaired?
Temporary image retention often fades over time. Permanent burn-in on OLED screens is typically irreversible, though some manufacturers include pixel-refresher features that may reduce its visibility. Prevention through varied content and proper settings is the best approach.
6. Flickering or Flashing Screen
What It Looks Like
Screen flickering manifests as rapid, irregular changes in brightness, making the image appear to flash, pulse, or strobe. The flickering may be constant or intermittent, and can range from subtle to severe enough to make viewing uncomfortable.
Common Causes
- Loose or failing cable connections (HDMI, power)
- Power supply board issues
- Incompatible video settings or refresh rates
- Faulty backlight inverter (LCD/LED TVs)
- Main board problems
- External interference from other devices
- Unstable electrical supply
Affects All Brands
Flickering can affect Samsung, LG, Sony, Hisense, TCL, and all other TV brands regardless of display technology (LCD, LED, OLED, QLED).
Can It Be Repaired?
Yes, most flickering issues are repairable. Professional diagnosis can identify whether the problem is with connections, power supply, or internal boards. Many cases are resolved by replacing faulty components or correcting settings.
7. Dark Spots or Shadow Areas
What It Looks Like
Dark spots appear as localized areas of reduced brightness or complete darkness on the screen. They may look like shadows, dark patches, or vignetting effects. Unlike dead pixels, these spots are larger and more diffused.
Common Causes
- Pressure damage to the LCD panel layers
- Moisture or liquid damage inside the screen
- Failed LED backlights in specific zones
- Separation of LCD panel layers
- Impact damage without visible external cracks
- Manufacturing defects
Affects All Brands
Dark spots can occur on LCD and LED TVs from any manufacturer, including Samsung, Sony, LG, TCL, Hisense, and others. The specific appearance may vary based on the backlight technology used (edge-lit vs. full-array).
Can It Be Repaired?
Repairability depends on the cause. If related to backlight issues, technicians may be able to replace LED strips. Pressure damage or panel separation typically requires screen replacement, which is often not cost-effective.
8. Color Distortion and Tint Issues
What It Looks Like
Color distortion presents as incorrect colors across the entire screen or in specific areas. Your screen might have a pink, green, blue, or yellow tint. Images may appear washed out, oversaturated, or completely wrong in color representation.
Common Causes
- Incorrect picture settings (color temperature, tint)
- Faulty T-CON board or main board
- Loose or damaged internal ribbon cables
- Aging panel components
- Graphics processor issues
- Magnetic interference (less common with modern TVs)
- Failed color processing circuits
Affects All Brands
Color issues can affect any television brand and technology, from budget models to premium Sony Bravia, Samsung QLED, or LG OLED displays.
Can It Be Repaired?
Yes, if caused by settings, cables, or board issues. Professional technicians can recalibrate the display, reconnect cables, or replace faulty circuit boards. Panel-level color issues are more challenging and expensive to repair.
9. White Screen or No Picture (With Sound)
What It Looks Like
Your TV powers on and you can hear sound, but the screen displays only white (or sometimes other solid colors). The backlight is clearly on, but no image appears.
Common Causes
- T-CON board failure
- Damaged main board
- Loose or disconnected panel cables
- Failed graphics processor
- Firmware corruption
- Power supply providing incorrect voltages
- Panel driver failure
Affects All Brands
This issue can occur on Samsung, LG, Sony, TCL, Hisense, and all other brands, affecting LCD, LED, and occasionally OLED displays.
Can It Be Repaired?
Yes, in most cases. This is often a repairable issue involving board replacement, cable reconnection, or firmware updates. Professional diagnosis is essential to identify the specific component failure.
10. Backlight Failure (Black Screen with Faint Image)
What It Looks Like
The TV appears to be on, and you might see a very faint image if you shine a flashlight at the screen, but there’s no backlight illumination. The screen remains black or extremely dark despite the TV being powered on.
Common Causes
- Failed LED backlight strips
- Power supply board issues
- Inverter board failure (older LCD TVs)
- Loose backlight cable connections
- Backlight driver circuit failure
- Complete LED array failure
Affects All Brands
Backlight failure affects LCD and LED TVs from all manufacturers. OLED TVs don’t have separate backlights, so they exhibit different failure patterns.
Can It Be Repaired?
Yes, this is often repairable and is one of the more common professional TV repairs. Technicians can replace LED strips, repair power supply boards, or fix backlight driver circuits. Repair is typically more cost-effective than replacement.
11. Vertical or Horizontal Bands and Patches
What It Looks Like
Unlike single lines, bands appear as wider sections of discoloration or brightness variation running vertically or horizontally across the screen. These may be constant or change with different content.
Common Causes
- Localized backlight LED failures (LED TV zones)
- T-CON board issues affecting specific regions
- Panel processing errors
- Cable connection problems
- Electromagnetic interference
- Power fluctuations affecting display zones
Affects All Brands
Banding issues can affect Samsung, LG, Sony, and all other brands, particularly those with zone-based backlight systems like full-array local dimming displays.
Can It Be Repaired?
Depending on the cause, these issues may be repairable through board replacement or backlight repair. Professional assessment can determine if repair is economical.
12. Screen Ghosting and Motion Blur
What It Looks Like
Ghosting appears as trailing shadows or afterimages following moving objects on screen. Motion blur makes fast-moving content appear smeared or unclear. While some motion blur is normal on lower-end TVs, excessive ghosting indicates a problem.
Common Causes
- Slow pixel response time (inherent to some LCD panels)
- Incorrect motion smoothing settings
- Aging display components
- Processing lag in the TV’s electronics
- Incompatible refresh rate settings
- Panel degradation
Affects All Brands
Motion issues can affect any brand, though they’re more common on budget models. Even premium brands like Samsung, Sony, and LG can experience these issues if settings are incorrect or components fail.
Can It Be Repaired?
Settings-related motion issues can often be resolved through proper calibration. Hardware-related ghosting from aging panels is typically not economically repairable.
