    13 Common TV Faults We Diagnose & Fix On-Site

    Our certified electronics technicians troubleshoot and resolve all screen display, backlight array, power supply, and motherboard faults directly at your premises:

    01
    TV Has Sound but Screen is Completely Black (No Picture / Backlight Problem)

    Root Technical Cause: Burnt LED backlight strip array, defective constant-current LED driver IC, or open-circuit boost inverter rail. Display panel is receiving video signals, but lacks backlight illumination.
    Our Solution: Full set 100% brand-new OEM aluminum-core LED backlight strip replacement with thermal conductive backing and driver voltage recalibration.

    02
    TV Has No Power / Completely Dead (No Standby Light / Won't Turn On)
    Root Technical Cause: Blown ceramic input surge fuse, ruptured primary electrolytic filter capacitors (450V), or shorted MOSFET switching transistors on the Power Supply Unit (PSU).
    Our Solution: Power Supply Board circuit rebuild, high-voltage filter capacitor swap, and primary rectifier safety restoration.
    03
    TV Damaged by Lightning Strike & High Voltage Power Surges
    Root Technical Cause: Severe thunderstorm lightning spike entering via electrical wall socket or HDMI/Astro cable, destroying the main SoC processor and power rail voltage regulators
    Our Solution: Component-level micro-soldering rework, voltage regulator IC replacement, or genuine OEM mainboard replacement with surge protection upgrade.
    04
    Loud Popping or Explosion Sound Inside TV Followed by Burning Smell
    Root Technical Cause: Primary high-voltage smoothing capacitor rupturing under heat stress, or catastrophic short-circuit of the primary PWM switching IC.
    Our Solution: Deep PCB de-carbonization, damaged copper trace restoration, and installation of heavy-duty Japanese grade 105°C rated capacitors.
    05
    Screen Polarizer Peeling, Wrinkling, or Burnt White Fog (Heat Damage)

    Root Technical Cause: Thermal degradation of the optical polarizing film layer caused by high ambient room heat and sunlight, resulting in wrinkled, burnt, or milky white patches.
    Our Solution: Precision optical polarizer film peeling, residue adhesive solvent cleaning, and machine-aligned anti-glare polarizer lamination.

    06
    Screen Shaking, Ghosting, Double Image & Vertical Jittering
    Root Technical Cause: Degraded panel glass Gate-in-Panel (GIP) clock synchronization lines or defective TAB/COF side bonding chips losing clock pulse timing.
    Our Solution: Micro-precision clock line modification (tape-cut signal isolation / bypass jumper method) and T-Con frequency synchronization.
    07
    Red Standby Light Blinking Continuously (Protection Error Code)
    Root Technical Cause: Internal protection circuit triggered by power board over-current, LED backlight short-circuit, or main processor communication timeout (e.g. Sony 6-blink error).
    Our Solution: Digital diagnostic blink-code error retrieval, power rail voltage stabilization, and safety protection loop reset.
    08
    TV Auto Restart Loop / Stuck on Boot Logo (Reboot Problem)
    Root Technical Cause: Corrupted eMMC / NAND Flash memory chip firmware, failing BGA processor solder joints from thermal expansion, or unstable auxiliary 3.3V standby regulator.
    Our Solution: Mainboard eMMC memory chip re-programming, factory firmware reflashing, or genuine mainboard module replacement.
    09
    Screen Displays an Intense Blue, Violet, or Purple Color Tint
    Root Technical Cause: Factory LED backlight phosphor coating burnt away from extended operating hours, shifting color spectrum from pure white to intense violet/blue.
    Our Solution: Full set replacement with 100% genuine high-CRI pure white LED backlight arrays, restoring true vibrant colors.
    10
    Picture Displayed Normally but No Sound from Built-In Speakers
    Root Technical Cause: Blown Class-D audio amplifier IC on mainboard, torn speaker voice coils, or corroded speaker output connector wiring.
    Our Solution: OEM stereo internal speaker module swap and audio amplifier circuit micro-soldering rework.
    11
    Half of Screen is Dark While the Other Half is Normal Brightness
    Root Technical Cause: Burnout of one channel on the dual-channel backlight driver board or disconnected flex ribbon cable on one side of panel buffer.
    Our Solution: Backlight driver dual-rail voltage balancing, LED channel repair, and source buffer ribbon re-seating.
    12
    Bright White Spots / Halo Rings Shining Through the Screen
    Root Technical Cause: Optical acrylic diffuser lenses fallen off from the LED backlight strips inside due to dried heat-degraded glue.
    Our Solution: Disassembly of optical diffusion layers, thermal epoxy lens re-bonding, or full new backlight bar installation.
    13
    HDMI 'No Signal' from Astro Box, Android TV Box, PS5, or Apple TV
    Root Technical Cause: Burnt HDMI switch selector IC chip caused by hot-plugging cables while powered, lightning surge, or electrostatic discharge (ESD).
    Our Solution: SMD micro-soldering replacement of HDMI receiver controller chip and ESD protective diode replacement.

    Frequently Asked Questions

    Why does my TV have sound but the screen is totally black?

    This is the #1 most common fault in modern LED/LCD TVs. The TV display panel is working, but the internal LED backlight strips have burnt out, meaning no light passes through the screen. We replace the complete LED backlight set on-site in under 60 minutes.

    Yes! Lightning power surges and electrical pops typically blow the Power Supply Board (PSU) or mainboard chips. Our certified technicians perform component-level micro-soldering or replace the board on-site with genuine OEM parts.

    Our on-site inspection and testing fee is a flat RM60 across KL and Selangor. If you proceed with the repair work, this RM60 fee is 100% WAIVED.

    If the front glass panel has physical internal cracks or impact lines, replacing the glass panel usually costs almost as much as buying a brand-new TV. We specialize in fixing all electronic, backlight, motherboard, power supply, and peeling polarizer faults as long as the glass is intact.

    We issue a formal 30-Day Written Warranty covering all installed genuine OEM replacement parts, LED backlight strips, and technician workmanship for complete peace of mind.

    We accept Cash and Instant Online Banking / DuitNow QR Transfer upon job completion and after you have personally tested the restored 4K picture and sound.
