What is Sony TV Backlight Failure?
Backlight failure occurs when the LED strips behind your Sony TV screen stop working, leaving you with a very dark or completely black screen. You might still hear sound, and if you shine a flashlight on the screen, you can faintly see images. This is one of the most common TV repair issues affecting Sony Bravia models.

Signs Your Sony TV Backlight Has Failed
You’ll know it’s a backlight issue if you experience any of these symptoms:
The TV turns on but the screen remains black or very dark. You can hear sound playing normally. When you shine a flashlight or phone torch at the screen, you can see a faint image. The Sony logo appears briefly when turning on, then the screen goes dark. Half of the screen is darker than the other half. You see vertical or horizontal dark bands across the screen.
Detailed Repair Process
Step 1: Diagnosis and Assessment
A qualified technician will first confirm the backlight failure by testing the screen with a flashlight to check for visible images. They’ll open the back panel to inspect LED strips for damage or burnout. The power supply board will be tested to ensure proper voltage delivery to the backlight. The T-con board and main board connections will be checked for any loose cables.
Time Required: 30-45 minutes
Cost: Usually free or KSh 500 – KSh 1,500
Step 2: Disassembly
The TV will be carefully laid face-down on a soft, clean surface to prevent screen damage. The back cover will be removed by unscrewing all perimeter screws. Internal metal shielding and protective covers will be taken off. All cable connections will be photographed or labeled for proper reassembly. The LCD panel will be separated from the backlight assembly.
Time Required: 45-60 minutes
Important: This requires precision as the screen is extremely fragile
Step 3: Backlight Replacement
Faulty LED strips will be carefully removed from the panel. The reflector sheets and diffuser layers will be cleaned or replaced if damaged. New LED strips compatible with your Sony TV model will be installed. All strips will be tested before reassembly to ensure even illumination. Proper adhesive and mounting will be applied to secure new LED strips.
Time Required: 1-2 hours
Critical: Using original or high-quality compatible parts ensures longevity
Step 4: Reassembly and Testing
The LCD panel will be carefully repositioned over the new backlight assembly. All protective layers and diffuser sheets will be properly aligned. Cable connections will be restored according to labels or photos. The metal shielding and back cover will be reattached. Multiple test patterns will be run to check for uniform brightness, color accuracy, and no dead spots or bright spots.
Time Required: 45-60 minutes
Final Check: Extended burn-in test for 2-3 hours recommended
Factors Affecting Repair Cost
TV Model and Age: Newer Sony Bravia models with Android TV may have more expensive parts. Older models might require harder-to-find LED strips, increasing costs.
Extent of Damage: Single LED strip failure is cheaper than multiple strip replacement. Additional power supply or board damage increases total cost.
Location: Nairobi repair shops typically charge KSh 1,000 – KSh 3,000 more than upcountry technicians. Authorized Sony service centers charge premium rates but offer warranties.
Technician Expertise: Experienced technicians with specialized tools may charge more but reduce risk of further damage. Mobile repair services (coming to your home) add KSh 1,000 – KSh 2,500 to the cost.
Parts Quality: Original Sony parts cost 30-50% more than compatible alternatives. Generic LED strips are cheaper but may have shorter lifespan.
Should You Repair or Replace Your Sony TV?
Repair Makes Sense When:
Your TV is less than 5 years old and was originally a mid-range to premium model (cost over KSh 40,000 new). The repair cost is less than 40% of buying a comparable new TV. Only the backlight needs replacement with no other major issues. You have a larger screen (55 inches or more) where replacement is very expensive. The TV has features you value that aren’t available in budget replacements.
Consider Replacement When:
Your TV is over 7 years old and showing multiple issues. The repair cost exceeds 50% of a new TV’s price. You have a smaller TV (32-43 inches) where new models are affordable. The main board, power supply, and backlight all need replacement. You want to upgrade to newer technology like 4K or smart features.
How to Find a Reliable Technician
Look for technicians with at least 3-5 years experience specifically with Sony TVs. Ask for references or check online reviews on Google or Facebook business pages. Request a detailed written quotation breaking down parts and labor costs. Ensure they offer a warranty on both parts and labor (typically 1-3 months). Verify they have proper tools including anti-static equipment and testing meters. Ask to see the replacement parts before installation to verify quality.
Warranty and Guarantee
Most reputable repair shops in Kenya offer a warranty period of 1 to 3 months on backlight repairs. This covers the replacement LED strips against premature failure and labor costs if the same issue recurs. Always get the warranty terms in writing on your receipt or service agreement.
Original Sony parts typically come with longer warranty periods (3-6 months) compared to compatible parts (1-3 months). Some technicians offer a money-back guarantee if the repair doesn’t solve the problem.
Prevention Tips to Extend Backlight Life
Keep your Sony TV in a well-ventilated area to prevent overheating that damages LED strips. Avoid setting brightness levels to maximum for extended periods. Use a voltage stabilizer or UPS to protect against power surges common in Kenya. Turn off the TV when not in use rather than leaving it on standby all day. Clean ventilation holes regularly to prevent dust buildup affecting cooling. Keep the TV away from direct sunlight which can cause uneven heating.
DIY vs Professional Repair
While some tech-savvy individuals attempt backlight replacement themselves, this is generally not recommended for Sony TVs. The LCD panel is extremely fragile and can crack easily during disassembly. LED strips must be precisely matched to your specific TV model. Without proper anti-static precautions, you risk damaging other components. A mistake during DIY repair could turn a KSh 12,000 fix into a complete write-off.
Professional repair is strongly recommended unless you have previous experience with TV repairs and the proper tools.
Typical Repair Timeline
Drop-off Diagnosis: Same day to 1 day
Parts Ordering: 1-3 days (if parts need to be sourced)
Actual Repair: 2-4 hours
Post-Repair Testing: 2-3 hours
Total Time: 2-5 days from drop-off to pickup
Some repair shops offer express service for an additional KSh 1,000 – KSh 2,000, completing the repair within 24 hours if parts are available.
Payment Options
Most repair shops in Kenya accept cash payments with some offering M-Pesa for convenience. Larger authorized service centers may accept credit/debit cards. Some shops require a 50% deposit before ordering parts, with the balance due on completion. Always request an official receipt for your payment and keep it with your warranty documentation.
Conclusion
Sony TV backlight repair in Kenya ranges from KSh 8,000 to KSh 25,000 depending on your TV size and the extent of damage. For most Sony TV owners with models under 5 years old, repair is a cost-effective solution compared to buying a new television. Choose a reputable technician, insist on quality parts with warranty, and you can enjoy several more years from your Sony TV.
Remember to get multiple quotations before committing to a repair, and don’t hesitate to negotiate prices, especially in independent repair shops. With proper care after repair, your Sony TV’s new backlight should last another 3-5 years or more.
