Certified technicians dispatched to you — same day.
The LG QNED84 has carved out a strong reputation among Nairobi buyers looking for upgraded picture processing within LG's QNED range, and as adoption has grown, so has demand for reliable local repair support. Pto-Logic Technologies has serviced a steady stream of QNED84 units and understands the specific fault patterns this model tends to develop.
One of the more frequent issues we diagnose is backlight degradation, where the screen develops dark patches, dimming, or flickering over time. This is generally caused by failing LED backlight strips or a fault in the backlight driver section of the power supply board. We test each backlight zone individually to confirm the exact location of failure, which allows for targeted, cost-effective repairs rather than full panel or board replacement.
Power circuit faults are common across Nairobi due to grid voltage fluctuations, and the QNED84 is no exception. We regularly see capacitor degradation, power board failures causing the TV to not power on, and intermittent shutdowns during use. Each of these is tested on the bench with proper equipment, and we explain to customers exactly which component failed and why, rather than offering vague explanations.
The QNED84's webOS smart platform can experience the same software-level issues seen across LG's smart TV range: sluggish app performance, failed firmware updates that interrupt normal boot-up, and Wi-Fi or Bluetooth connectivity dropouts. Our approach prioritizes safe software resets and reflashing before recommending any hardware replacement, which keeps costs lower for customers in most cases.
We also handle HDMI port repairs, a common need in homes and offices where the TV serves multiple input devices such as DSTV/GOtv decoders, gaming consoles, and laptops. Damaged or loose HDMI ports are repaired or replaced without requiring a full main board swap whenever the fault is isolated to the port itself.
Audio issues — including muffled sound, complete audio loss, or one-channel failure — are diagnosed by testing the speaker units and the main board's audio output stage separately, ensuring the correct component is replaced.
Pto-Logic Technologies stocks commonly needed QNED84 parts, including power boards, main boards, backlight strips, remote controls, and speaker assemblies, enabling most repairs to be completed within 24 to 48 hours. For screen damage from drops or impact, we provide a clear cost comparison between panel repair and replacement so customers can make an informed decision.
Our service area covers Nairobi comprehensively, from Westlands and Parklands to Donholm and Imara Daima, with collection and drop-off service available alongside in-shop repairs at our Luthuli Avenue location.
