Ageing supply capacitors
Capacitors that have lost capacity cannot hold voltage under load, producing shutdowns after warm-up.
TV Problem Guide
TV Power Problems
Power complaints that are not a completely dead set — restarts, shutdowns, delayed start-up — usually mean the supply is working but no longer stable under load.
Symptoms you may notice
- TV switches off on its own after some time
- Set restarts in a loop
- Takes several minutes to start
- Standby light stays on but nothing happens
- Clicking or buzzing from the rear of the set
Possible causes
Protection triggering
The set detects an over-current condition, often related to backlight strings, and shuts itself down to stay safe.
Poor mains supply
Low or fluctuating voltage causes symptoms that look exactly like an internal fault.
Firmware boot loops
On Smart models, a failed update can create a restart cycle that no amount of power work will fix.
What a technician checks
- Rail voltages measured cold and after warm-up
- Capacitor condition and ESR where accessible
- Backlight current draw
- Mains voltage logged during the visit
- Firmware state on Smart models
Safe checks you can do first
- Plug directly into a wall socket, not an extension board
- Note how many minutes the TV runs before shutting down
- Keep ventilation clear behind and above the set
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.

Frequently Asked Questions
Where the mains supply is genuinely unstable, yes. The technician measures it before recommending one.
Both are possible. Restarts right after an update lean software; restarts after warm-up lean hardware.
Continuous restart cycling is best avoided. Switch the set off at the socket until it is inspected.
