Physical Glass & Screen Damage Notice
Revive TV Repairs specialises exclusively in internal electronic, board-level, and backlight restorations. We do NOT repair or replace physically broken, cracked, or shattered TV screens. Replacing physical panels typically costs more than a brand-new TV.
Our Comprehensive TV Repair Services
Direct component restoration and factory board replacement carried out on-premises in Johannesburg and Pretoria.
TV Power Supply Repairs
Resolution of standby circuit failures, blown fuse relays, surge-damaged bridge rectifiers, and swollen capacitors resulting from load shedding spikes.
TV Backlight Replacement
Replacement of burnt-out LED arrays, edge-lit diodes, or faulty constant-current inverter drivers when audio functions normally but the picture is black.
TV Mainboard & Logic Board
Diagnosis of processor failure, frozen operating systems, EEPROM memory corruption, and reballing/soldering of micro-components across all smart architectures.
TV Not Switching On
From continuous standby blinking codes (2-blink, 5-blink) to totally unresponsive sets. We isolate whether the bottleneck is power, secondary supply, or main IC.
Sound But No Picture
Audio is loud and crisp, remote changes channels, but the screen stays inky black. We check panel gate drivers, timing control boards (T-Con), and LED rail voltages.
TV Picture But No Sound
Clear visuals but zero volume or distorted buzzing. We test the audio amplifier IC, analog/optical output processors, and direct driver speaker cones.
TV Turning On & Off Constantly
TV reboots endlessly after displaying the brand logo, or turns off after exactly 5 to 10 minutes due to overheating protection circuits or corrupted NAND flash memory.
Smart TV & Wi-Fi Connectivity
Wi-Fi greyed out or disconnecting constantly, apps crashing (Netflix/YouTube), and motherboard ribbon cable interference resolved with new transceiver modules.
TV HDMI & Audio Port Repairs
HDMI sockets loose, bent pins from tension, or ports blown by lightning surges passing through DStv decoders, PlayStation 5, or soundbars.
LED, LCD, QLED & OLED Electronic Diagnostics
Whether you own a premium Samsung Neo QLED, LG OLED C-Series, Hisense ULED, or classic Sony Bravia, our mobile technicians carry high-precision multimeters, oscilloscope testers, and OEM diagnostic firmware programmers.
