Sound works, no picture: the most common fault we see
can you hear the channel's audio just fine, but there's no picture at all, or only a ghost-faint image you can barely see unless you shine a torch at the screen? That's the classic backlight fault, and it's the most common one we see.
the LED strips lighting the panel from behind burn out over time, and just one dead LED can take out the whole string.
hold your phone torch close to the running screen. A faint image behind the darkness confirms it's the backlight. The fix is straightforward: genuine LED strip replacement, which is our single most frequent repair — and far cheaper than a new TV.
