Need TV Repair Services in Nairobi?
Certified technicians dispatched to you — same day.
The LG QNED87 represents one of the more advanced models in LG's QNED mid-range lineup, offering Nairobi customers enhanced contrast and color performance suited to both everyday viewing and more demanding home entertainment setups. Pto-Logic Technologies has serviced a growing number of QNED87 units and applies a methodical, component-level approach to its repair.
Backlighting issues remain among the most common faults we diagnose on the QNED87, typically appearing as uneven brightness, dark zones, flickering, or full picture loss while audio remains functional. We test individual backlight zones and the driver circuitry on the power board separately to determine the precise cause, avoiding unnecessary full-board replacements and keeping repair costs aligned with the actual fault.
Power supply faults linked to Nairobi's variable electricity grid are also frequent. These range from complete failure to power on, to intermittent shutdowns during use, to standby-light error codes that require accurate interpretation. Our technicians confirm every diagnosis with proper bench testing rather than relying on assumptions, ensuring customers only pay for the parts that are actually faulty.
On the smart TV side, the QNED87 runs webOS and can develop typical software-related symptoms: slow app performance after extended use, failed firmware updates that interrupt normal startup, and Wi-Fi or Bluetooth connectivity drops affecting paired soundbars or audio devices. We address these through safe software resets and reflashing first, moving to hardware replacement only when a module fault is verified.
HDMI port faults are common given how frequently Nairobi households and offices switch between connected devices such as decoders, consoles, and laptops. We repair or replace damaged ports without requiring a full main board swap whenever the issue is isolated to the port itself. Audio problems, including distorted sound or complete audio loss, are diagnosed by testing speaker units and the main board's audio output stage independently to apply the correct fix.
For physical damage such as cracked panels, broken stands, or impact-damaged housing, Pto-Logic Technologies provides a clear and honest comparison of repair versus replacement costs, ensuring customers aren't pushed into an uneconomical repair.
We keep commonly needed QNED87 parts in stock, including power boards, main boards, backlight components, remote controls, and speaker assemblies, allowing most repairs to be completed within 24 to 48 hours. For parts requiring import, we provide realistic timelines and keep customers updated throughout.
Our service coverage extends across Nairobi, including Karen, Langata, Embakasi, and Kasarani, with both walk-in repair service at our Luthuli Avenue workshop and pickup arrangements available for larger or bulkier units.
