🛠️ MULTITECH DIAGNOSTIC BENCH — find the culprit in 3 steps

STEP 1 — The torch test 🔦 (the one that separates a smart purchase from a return): in the dark, switch the TV on and hold a torch right up against the screen. Can you make out an image? The panel and the main board work: your problem is the backlight (LED strips, driver or the backlight stage of the power supply). No trace of an image? Keep reading.

STEP 2 — Standby light and ear 👂: is the standby LED steady, blinking or dead? Can you hear relay clicks or channel audio? Each combination points to a different suspect in the table.

STEP 3 — Find your symptom:

What your TV does	Suspect no. 1	Also check
Completely dead, standby LED off	Power supply	fuse, mains cable
Standby LED blinks, won't start	Power supply	main board
Turns on and shuts off immediately	Power supply (protection)	main board, shorted LED strips
Sound OK, image visible only with a torch	LED strips	LED driver, power supply backlight stage
Sound OK, pitch black even with a torch	Main board (video circuit)	T-CON, LVDS flex
Dark areas or uneven brightness by zones	LED strips	LED driver
Vertical lines or half screen	T-CON	poorly seated LVDS flex
Odd colours or negative image	T-CON (gamma)	LVDS flex
Poor sound: distorted, rattling or one channel silent	Speakers	main board (audio stage)
Can't find WiFi networks or Bluetooth won't pair (Magic Remote, headphones)	WiFi/BT module	module flex cable, main board
Frozen image, artefacts, no response to the remote	Main board	firmware
Thin horizontal lines	⚠️ usually the panel (COF flex)	ask us before buying

💬 Unsure about your diagnosis? Message us BEFORE buying with your TV's full model number and the symptom: we'll tell you which part you need, no obligation — we'd rather advise you for free than process a return. And if the part still doesn't fix your fault, you have 30 days to return it and get your money back (return postage paid by the buyer).
