TCL TV half-dark screen — repair in Mumbai
One half or one strip of the screen is dark while the rest of the picture is normal. On a TCL set specifically, here is what that usually means.
Half-dark screens on TCL sets are almost always a backlight strip section, which is one of the more affordable repairs on these models.
What actually causes it
A failed section of LED backlight strip, or a T-CON fault driving only half the panel.
Check this before you call
Shine a torch close to the dark area in a dark room. If you can faintly see the picture there, the panel is alive and it is a backlight fault — which is the cheaper of the two.
Parts and turnaround for TCL
Good for panels and strips — TCL manufactures its own panels. Replacing the failed backlight strip section, or repairing the T-CON. Turnaround is normally 1–2 days, and the cost is backlight strip work is one of the more affordable repairs.
