Failed LED strings
One or more LED strips fail, and the driver shuts the backlight down to protect itself.
TV Problem Guide
LED TV Not Working
On LED televisions, two sections account for most failures: the power supply and the backlight. Identifying which one is involved takes minutes and decides the entire cost of the repair.
Symptoms you may notice
- Screen dark but sound plays normally
- Dim display or dark corner
- Set does not respond to power at all
- Picture visible only under a torch
- Set switches off shortly after starting
Possible causes
Backlight driver fault
The driver stage no longer supplies the required current, leaving a running set with an unlit panel.
Power board failure
The supply cannot start or hold the rails, which stops the set entirely.
Mainboard problems
Less common, but a mainboard fault produces no-start or no-image symptoms that need measurement to separate.
What a technician checks
- Torch test to confirm panel activity
- Backlight current and driver voltage
- Supply rails under load
- LED strip continuity where the assembly is opened
- Thermal inspection of the boards
Safe checks you can do first
- Check the socket and power cable with another appliance
- Look for a faint image with a torch held close to the screen
- Keep the set unplugged until it is inspected if it smells hot
How the service works
Book a visit, describe the symptom, and a technician inspects the television at your home. The fault is explained in plain language, the cost is quoted before work starts, and the repair proceeds only after you approve it.
Please do not open the television or work on internal boards yourself. Panels and power supplies can hold a charge even when unplugged, so internal checks should be left to a technician.
