What you'll notice
One half of the screen (often top/bottom or left/right) shows a normal image while the other half is blank, garbled or discoloured.
Why it happens
A T-Con board driving only one section of a dual-driven panel, or a failed connection on one side of the T-Con.
How we fix it
We isolate which half of the T-Con circuit has failed and replace the board — a well-understood, predictable repair.
Still not working?
If the checks above haven't restored your t-con board, this usually needs a technician. Our LED & LCD TV Repair service covers exactly this fault.
