What you'll notice
A normal picture briefly appears on power-up, then collapses into lines or blankness within seconds.
Why it happens
A T-Con board failing under load after an initial healthy moment, often heat-related.
How we fix it
We run the TV under sustained load to catch this exact pattern, then replace the T-Con board once confirmed.
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.
