LG matches the main board by EAX reference and variant: compare EAX70337404(1.1) and the label on your board with the photos, or message us via the eBay messaging system stating the full model of your TV (rear label) and we will confirm compatibility before you buy. Typical symptoms of a faulty main board: does not power on with power supply OK, frozen image, no signal on HDMI, does not respond to the remote.

🛠️ 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:
