✓ COMPATIBILITY AND SYMPTOMS

Verify that the BN44 reference on your board matches EXACTLY (including the final letter) before purchasing: the silkscreen marking on this board indicates BN44-01342A for the L75E70NA version (75") and BN44-01341A for the L85E70NA (85") — they are not interchangeable. Typical symptoms of a faulty power supply: TV that won't turn on, flashing standby light, relay clicking, random shutdowns, or backlight that fails to start. If in doubt, message us via the eBay messaging system stating your TV model and version and we will confirm compatibility.

🛠️ 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).
