What you'll notice
A small cluster of pixels stuck black, white or a single colour, or a patch of the screen with a visible discolouration.
Why it happens
Localised panel damage, sub-pixel failure, or — on OLED — early localised burn-in.
How we fix it
We assess the size and location of the affected area against the panel's cost and the TV's remaining useful life, and give you the honest repair-vs-live-with-it comparison.
Still not working?
If the checks above haven't restored your screen panel, this usually needs a technician. Our TV Screen Replacement service covers exactly this fault.
