✓ COMPATIBILITY

The EAX70302603(1.0) design is common to the QNED85 2026 range in 55" and 65". Important: the firmware is paired to the panel size — this unit is extracted from a 55" and carries V33.22.65 (label 1PB). LG matches the main board by part number and firmware: compare the EAX number 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.

🛠️ 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:

💬 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).
