Graphics Processor (GPU) Repair: Estimated Labour Charges and Prices in Nairobi
Provider: Pro-Logic Technologies, Kangari Building, Nairobi
The GPU (Graphics Processing Unit) in a smartphone handles rendering of all visual output: the user interface, video playback, gaming, and GPU-accelerated computational tasks like photo processing. As with the CPU, the mobile GPU is not a discrete removable component — it is integrated into the SoC alongside the CPU and other processors. Common GPU families found in phones sold in Kenya include the Adreno (Qualcomm Snapdragon), Mali (MediaTek/Samsung Exynos), Apple GPU (custom silicon), and Immortalis (ARM).
Symptoms of GPU Failure
- Screen shows graphical corruption: flickering, misaligned grids, colour noise, or artefacts during use
- Specific graphical glitches appear only under load (gaming, video) while the screen is fine at idle
- Phone crashes specifically when running GPU-intensive applications
- Display driver crashes logged in diagnostics pointing to GPU faults
- Screen shows static noise while the rest of the phone functions normally
GPU faults are relatively rare in isolation. Many apparent GPU symptoms are actually caused by the display driver IC or the display cable — both cheaper fixes that should be ruled out first.
Estimated GPU / SoC Rework Costs in Nairobi (2024–2025)
Since the GPU is inside the SoC, repair costs mirror SoC rework pricing:
| Platform | Rework Labour (KES) | Full SoC Replacement (Parts + Labour, KES) |
|---|---|---|
| MediaTek (Helio / Dimensity) | 2,500 – 7,000 | 5,000 – 22,000 |
| Qualcomm Snapdragon (mid-range) | 4,000 – 8,000 | 14,000 – 30,000 |
| Qualcomm Snapdragon 8-series | 6,000 – 12,000 | 28,000 – 58,000 |
| Apple A-series | 6,000 – 14,000 | Board replacement advised |
Display Driver IC First
Before any GPU rework is quoted, the display driver IC — a far cheaper and more accessible component — should be tested and replaced if faulty. Visual artefacts, lines, and flickering are more commonly caused by the driver IC or a loose display cable than by a GPU-level hardware fault.
Visit Pro-Logic Technologies at Kangari Building, Nairobi for a structured graphics fault diagnostic that rules out cheaper causes before SoC-level work is recommended.
