IR sensor + button board + microphones LG — EBR419143 (02 SRC1A)

Front assembly: IR sensor, power button, LED and microphones → with original bracket · C4_v2 chassis (Seronics) · Unused. Supplied mounted in its original bracket: this protects the part during shipping and, if your TV is the model listed in the advert, the swap is straightforward — no need to unclip the board or risk damaging it during handling

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?

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:
