TV screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser).

Test it now

Full-screen white, black and grey, then the three colours. Note what you see, on which colours, and whether it changes with pressure. Then answer the questions on the home page, or pick the matching symptom from the list below.

What it is

TV screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser). Run the full-screen colours and use the three questions below to land on the right one.

Can it be fixed?

Settings and software faults: yes. Cables and connectors: usually, as a small repair. Panel faults: replacement. The pages linked below say which is which for each symptom.

What to do

  1. Full-screen colours.
  2. Screenshot: fault in the screenshot = software or graphics, not the screen.
  3. Match the symptom to a page below.
  4. In warranty and no impact or pressure: claim before paying.

What a repair costs

United States$150–400 for a T-con or main board repair; a panel is usually more than a new TV under 50"
India₹2,500–8,000 for a board repair at a local TV technician; panels ₹8,000–30,000, usually not worth it under 43"

Warranty

Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).
