Is your Samsung UA55AU7700 or UA55CU7000 55 inch LED TV screen suddenly gone completely dark? Are you noticing rectangular dark zones appearing on specific sections of your display while the TV audio continues to work normally? This is not a panel fault — it is a classic symptom of a failed paired LED backlight strip in your Samsung 55 inch TV. The LED Backlight Strip for Samsung UA55AU7700 / UA55CU7000 55 Inch TV (10 LED 5+5 Configuration, 4 Pair Set) is a precision-engineered direct replacement set designed specifically for these two Samsung 55 inch models.
This complete 4 pair set includes all 8 strips required for a full Samsung UA55AU7700 and UA55CU7000 panel replacement. Each pair consists of two strips of 5 LEDs each — working together to illuminate one specific zone of the 55 inch panel with precise, balanced brightness. This 5+5 paired configuration is unique to select Samsung 55 inch models and cannot be substituted with standard single backlight strips — making this a specialist replacement part for these specific TV models.
Why Samsung UA55AU7700 and UA55CU7000 Use a Paired Strip Design
Samsung introduced the paired backlight strip architecture in its premium 55 inch TV models to achieve superior display zone control and more uniform brightness across larger screen areas. In the UA55AU7700 and UA55CU7000, the panel is divided into 4 lighting zones — each controlled by one pair of 5 LED strips. This design gives Samsung’s 55 inch panels better local brightness control compared to single-strip horizontal designs.
However this same paired design creates a very specific failure pattern when strips begin to age. Symptoms unique to paired backlight failure in Samsung UA55AU7700 and UA55CU7000 include:

⚠️ Critical Verification: Before ordering, open your Samsung 55 inch TV panel and confirm the 5+5 paired strip layout, total pairs (4) and total strips (8). Samsung 55 inch TVs use multiple different backlight configurations — the paired design in UA55AU7700 and UA55CU7000 is specific to these models and cannot be confirmed by model number alone.

Despite being different Samsung model numbers — UA55AU7700 being part of Samsung's AU7700 series and UA55CU7000 from the CU7000 series — both TVs use an identical 5+5 paired backlight strip configuration with 4 pairs totaling 8 strips. This shared specification is why one listing covers both models with a guaranteed direct fit for each.
The 55 inch panel in these Samsung models is divided into 4 lighting zones — each controlled by one pair of strips. When a single strip within one pair fails, its partner strip continues working but can only illuminate half the zone — creating a clearly defined rectangular dark area. As more strips fail, additional rectangular zones go dark until the entire screen blackens.
Backlight strip failure in newer Samsung models is often caused by voltage fluctuations in Indian power supply rather than age-related wear. Frequent power cuts, voltage spikes and inconsistent electricity supply accelerate LED failure in Samsung 55 inch panels significantly. Using a voltage stabiliser after repair is strongly recommended to extend the lifespan of your new replacement strips.
While both use a 5+5 paired design, the 55 inch strips are physically longer than the 49 inch variants to match the greater panel height of the larger screen. The two sets are not interchangeable — always order the strip set listed for your specific screen size and model number, never substitute based on LED configuration alone.
Yes — in a darkened room, power on your Samsung UA55AU7700 or UA55CU7000 and observe which rectangular section of the screen is dark. Each dark zone corresponds to one failed pair. However since all pairs age simultaneously, replacing only the visibly failed pair leaves the remaining pairs vulnerable to imminent failure — always replace the complete 4 pair set for a permanent repair.
The 4 zone paired backlight layout in the UA55AU7700 provides basic zone-level brightness control — not full local dimming. True local dimming requires many more independently controlled zones. However the 4 zone design does deliver noticeably better contrast and uniformity compared to single-strip backlight designs used in budget 55 inch TVs.
Start by labeling each pair position before removing old strips — marking which pair goes in which zone prevents confusion during reinstallation. Remove all 8 old strips completely before fitting any new ones. Install new pairs zone by zone from left to right, ensuring each strip connector is fully seated before moving to the next pair. Test the backlight before reassembling the panel.
This set is verified specifically for UA55AU7700 and UA55CU7000 — other Samsung AU or CU series 55 inch models may use different backlight configurations even within the same product family. Do not assume compatibility based on series name alone — always open your TV panel and verify the 5+5 paired layout with 4 pairs before ordering.
If your TV is within the Samsung warranty period, always claim warranty first — Samsung covers manufacturing defects including backlight failures within the warranty term. Only consider self-repair or third party repair using our replacement strips if your warranty has expired, as opening the TV panel yourself will void any remaining warranty coverage.

For urgent repairs across Mumbai, Bangalore, Chennai, Hyderabad, Kolkata and Pune, express shipping options are available at checkout — ensuring your replacement strips arrive as quickly as possible so your Samsung 55 inch TV is back in use with minimal downtime.
