At Pro-Logic Technologies, we repair a wide variety of television faults affecting both modern Smart TVs and traditional LED, LCD, OLED, and QLED televisions. Whether your television has suddenly stopped working or has gradually developed performance problems, our experienced technicians use professional diagnostic equipment to identify the exact cause of the fault before recommending the appropriate repair.
Televisions are complex electronic devices made up of power circuits, display systems, signal processing boards, audio components, and software. A fault in any one of these systems can affect the overall performance of the television. Our technicians are trained to diagnose and repair faults at component level whenever practical, helping customers restore their televisions without unnecessary replacement of complete circuit boards.

Every repair begins with a detailed inspection to determine the root cause of the fault. This allows us to recommend repairs based on technical findings rather than guesswork.
Black Screen and Dark Screen Repairs
One of the most common faults affecting televisions is a black screen or dark screen. Many customers assume that a black screen means the display panel has failed, but this is not always the case. In many televisions, the problem is caused by defective LED backlights, a faulty power supply board, damaged display control circuitry, or motherboard issues.
A television with sound but no picture often indicates a failed backlight system. Our technicians carefully inspect the LED strips, backlight driver circuits, and power supply to identify the source of the problem. Where appropriate, defective components are replaced and the television is tested to ensure uniform brightness and clear picture quality.
If the television displays a very dim image that is only visible under a flashlight, this usually confirms a backlight-related fault. We perform detailed diagnostics before recommending any repair.
Television Power Problems
If your television refuses to power on or repeatedly shuts down, several components may be responsible. Common causes include:
- Damaged power supply boards
- Blown fuses
- Faulty capacitors
- Short circuits
- Failed voltage regulators
- Burnt MOSFETs
- Defective standby circuits
- Motherboard faults
Our technicians use professional testing equipment to trace power circuits and verify voltage levels before replacing any components. This approach improves repair accuracy and helps prevent recurring faults.
Picture Quality Problems
Picture quality issues can develop gradually or suddenly. We diagnose and repair televisions experiencing:
- Blurry images
- Colour distortion
- Screen flickering
- Bright or dark patches
- Image ghosting
- Screen tearing
- Vertical and horizontal lines
- Display synchronization problems
- Poor contrast
- Low brightness
- Display signal loss
These faults may originate from the display panel, T-Con board, ribbon cables, LED backlight system, or motherboard. Accurate diagnosis is essential before any repair is performed.
Smart TV Software Problems
Modern televisions rely on software for streaming, internet connectivity, and application management. We diagnose Smart TV software issues including:
- Slow operating systems
- Endless reboot loops
- Application crashes
- Firmware corruption
- Wi-Fi connection failures
- Bluetooth pairing issues
- Google account synchronization errors
- YouTube loading failures
- Netflix playback problems
- Software update failures
Where appropriate, we restore software functionality by repairing or reinstalling compatible firmware and testing all Smart TV features after the repair.
This careful diagnostic approach helps ensure that every television receives the attention it requires, whether the problem is hardware-related, software-related, or a combination of both.
