Repairs for the 10 Most Common TV Faults
Modern televisions pack complex electronics into a slim frame, and even a small fault can leave you staring at a dark or distorted screen. At Imperial Appliances, our TV repair services cover every major brand and fault type, from cracked panels to failing power boards. Below are the 10 TV faults our technicians see most often, what causes them, and how our TV repair services resolve each one.
1. No Power at All
This is the fault we see most. It's almost always a failed capacitor on the power supply board, which swells and loses charge over years of use. We test the board with a multimeter and replace only the failed parts — far cheaper than a full board swap.
2. Sound Works but the Screen Stays Black
If you can hear the programme but see nothing, the backlight has likely failed. LED strips behind the panel burn out individually, and once too many fail the picture disappears. We replace the faulty strips rather than the whole panel wherever possible.
3. Picture Is Fine but There's No Sound
A dead audio output section or a blown internal speaker is the usual culprit — sometimes it's just a loose ribbon cable between the mainboard and speaker unit, which our TV repair services technicians check first.
4. Screen Flickering On and Off
Flickering points to loose internal connections or a failing T-con (timing control) board, which tells the panel how to display each frame. Left unresolved, it usually worsens into total picture loss, so it's worth booking a repair early.
5. Coloured or Distorted Lines on Screen
Vertical or horizontal lines usually mean panel damage or a faulty T-con board. Stable, few lines often respond to a board repair; lines that multiply over time point to panel replacement instead.
6. Cracked or Physically Broken Screen
Impact damage cracks the glass or the LCD/OLED layer beneath it. There's no repairing a cracked panel — only replacement — but our TV repair services team sources compatible panels for most major brands at a fraction of the price of a new set.
7. HDMI Port Not Recognising Devices
Ports wear out from repeated plugging and unplugging, and pins can bend or corrode. We re-solder or replace the affected port directly on the board, usually a same-day fix.
8. Smart TV Won't Connect to Wi-Fi
This is often a software issue rather than hardware — outdated firmware, a corrupted network module, or router compatibility. Our TV repair services include firmware updates and module replacement when a reset alone doesn't solve it.
9. Colours Look Washed Out or Wrong
Faded, green-tinted, or oversaturated colours point to a failing colour processing chip on the mainboard — usually a component-level repair rather than a full board swap, which keeps the cost down.
10. TV Randomly Restarts or Shuts Off
Overheating power components are the most common cause, often worsened by dust blocking ventilation. We clean the internals and replace overheating capacitors so the set runs cool and stable again.
