Product Description

Restore the professional-grade brightness and picture clarity of your television with the 6LED 3V 32" 57CM Straight TMN-66 Backlight Strip. Measuring 57cm in length, this replacement strip is specifically engineered for 32-inch LED TVs that utilise the TMN-66 hardware architecture. Each strip features 6 high-intensity LED beads, each operating at a precise 3V, delivering uniform and flicker-free illumination across the display. At Robogears, we ensure these strips are manufactured on a premium aluminium substrate, which provides significantly better heat dissipation than standard plastic or fibreglass alternatives. This industrial-grade thermal management prevents the LEDs from overheating, ensuring consistent performance and preventing dark patches or premature burnout.

Detailed Key Features

TMN-66 Model Compatibility: Designed as a direct-fit replacement for the widely used TMN-66 backlight configuration in 32-inch TVs.
Aluminium Thermal Core: Constructed with a high-conductivity aluminium base that rapidly draws heat away from the LED chips, ensuring an extended service life.
Consistent 3V Power Balance: Each LED is rated at 3V, making the strip fully compatible with standard 18V-range constant-current backlight drivers.
Precision Optical Lenses: Equipped with high-clarity diffuser lenses that spread light evenly across the panel, eliminating "bright spots" or "shadowing."
Industrial Reliability: Engineered to maintain original factory brightness and colour temperature over thousands of hours of active display time.

All Technical Details

Total Drive Voltage: Approximately 18V DC per strip.
Substrate Type: Rigid aluminium (Al) for thermal stability and straightness.
Colour Temperature: Calibrated cool-white spectrum for natural colour rendering.
Interface: Standard 2-pin interface for secure electrical bonding or easy soldering.
Profile: Slim-line straight design for easy placement within original reflective sheets and light guide plates.

Prototyping & Engineering Tips (Robogears Exclusive)

Diagnosis Tip: If your 32-inch TV has sound but the screen remains dark (or flashes briefly before going black), use an LED tester to check the strip. A 6-LED 3V strip should show a total forward voltage drop of roughly 18V.
The "Full Set" Rule: For any professional repair at your Pimpri facility, we strongly recommend replacing the entire array (all strips) at once. Mixing new strips with old, aged ones can cause current imbalances that lead to the remaining older strips failing shortly after the repair.
Thermal Bonding: Ensure the metal chassis of the TV is perfectly clean of old adhesive residue before installation. Use high-quality thermal double-sided tape or thermal glue to ensure the aluminium strip makes maximum contact with the chassis for heat dissipation.
Handling Note: Be careful while handling the diffuser lenses; if a lens is knocked loose, it can be reattached with a tiny drop of clear UV-curing adhesive to ensure the optical centre remains aligned.
