This is the unique part number. It will be printed on the tuner’s metal shielding can or on its PCB. The “1220” might represent a dimension (12mm x 20mm) or a product family code. “00011” is the specific variant—likely tuned for a certain geographical market (e.g., Europe’s DVB-T/T2 or North America’s ATSC). Crucially, “12” can also appear as “1Z” in some manufacturer markings due to typographic conventions.
A: Check your antenna and cable first. If the issue persists, the tuner’s AGC circuit may differ slightly. Some Full tuners need a software alignment via the service menu. Enter service mode (often “Menu + 1147” on TCL) and run the “Tuner AGC Auto” routine.
