Sony RGB LED (True RGB) Screen Repairs, Luthuli Ave - Nairobi
True RGB LED televisions occupy a special place in the history of premium display technology. Rather than using white LEDs filtered through the LCD panel, these rare and sophisticated sets employ individually driven red, green, and blue LEDs behind the panel to produce an exceptionally wide colour gamut and precise backlight control. Sony pioneered this approach in landmark products such as the BRAVIA XBR-45KX2 and the legendary Qualia 005, and while True RGB backlighting never became a mass-market configuration, a dedicated community of enthusiasts and collectors in Kenya and beyond still treasures these sets. Keeping a True RGB television running requires rare expertise and rare parts, and Pro-Logic Technologies on Luthuli Avenue has the diagnostic depth to provide both.
Why True RGB Screens Are Special
In a True RGB television, the backlight is not merely a light source but a colour-producing system in its own right. The red, green, and blue LEDs are calibrated to work in harmony with the LCD panel's filters, and the television's colour management depends on this calibration remaining accurate. This design yields colour fidelity that many conventional sets still struggle to match. It also creates a distinctive repair challenge: LED failures do not merely dim the screen, they shift its colour. A screen that suddenly appears magenta, cyan, or yellow-toned is often signalling that one channel of the RGB backlight has degraded or failed entirely. Recognizing this symptom requires genuine familiarity with the technology, which general technicians rarely possess.
Common True RGB Screen Faults
The faults we diagnose and repair on RGB LED sets include: colour casts across the screen or in zones, caused by the failure of one LED colour channel; black screen with sound, indicating total backlight or power failure; uneven brightness or patchy colour from aged or mismatched LEDs; flickering in a single colour channel, typically a driver board fault; dark edges or corners from strip degradation; lines and ghosting from T-con or panel ribbon faults; and age-related dimming of the entire backlight. Because these televisions are legacy pieces, panel cracks are usually uneconomical to repair, and our advice in such cases is candid about preservation versus disposal.
Our Repair Process
Every True RGB repair at Pro-Logic Technologies begins with a thorough diagnostic of the backlight channels, driver boards, power supply, and image circuitry. Because parts for these sets are scarce, we combine sourcing through specialist international supply channels with board-level component repair, rebuilding driver circuits and matching replacement LEDs to the original colour specifications wherever possible. You receive a written quotation and a realistic assessment before work begins. Calibration is the final and critical step: after any backlight work, the television's colour balance must be verified and adjusted so that the screen performs as its designers intended. Repairs of this kind take longer than modern sets, often several days, but the results reward the patience of any enthusiast.
Repair or Replace
For owners of True RGB televisions, replacement is rarely the point; preservation is. These sets were built to standards that make them worth maintaining, and a professionally rebuilt backlight can extend a legendary television's life by many years. Our role is to give collectors and enthusiasts an honest assessment of what restoration will cost and what it will achieve.
