Why is my LG TV playing sound but showing a black screen?

This is almost always due to failed LED backlight strips behind the LCD diffuser sheet, or a blown inverter LED driver circuit on the power supply board. When you shine a flashlight close to the screen, faint images can still be seen. We replace the full backlight array with genuine LG LED strips.

Can you repair LG TV motherboards without costly complete board replacement?

Yes. Our electronics lab specializes in component-level micro-soldering, replacing shorted SMD capacitors, reprogrammed eMMC flash ICs, DC-to-DC converters, and HDMI port chips at a fraction of whole-board replacement cost.

Do you offer safe pickup and drop for larger 55-inch and 65-inch OLED TVs?

Yes. While preliminary diagnosis is performed at your home, delicate panel disassembly is transported to our Poonam Sagar Complex lab using custom padded flight cases, returning with 90-day warranty documentation.

Advanced LG Smart TV Electronics Repair

LG Smart TVs, powered by webOS and Alpha series AI processors, combine high-density motherboards with edge-lit or direct-array LED backlights. When an authorized company center recommends complete, prohibitively expensive screen or board replacements, our electronics lab offers targeted component-level restorations.

Centrally based at Ground Floor, Poonam Sagar Complex, Mira Road East, our facility is equipped with stereoscopic soldering microscopes, infrared BGA rework stations, and digital oscilloscope signal analyzers.

Common TV Symptoms We Resolve

Audio Working, Screen Black

Caused by deteriorated LED backlight strips or open constant-current boost drivers. We install complete, factory-matched aluminum-substrate LED sets.

Power Standby LED Blinking

Indicates a protection lockout from the switched-mode power supply (SMPS) due to swollen high-frequency filter capacitors or shorted Schottky rectifiers.

webOS Bootlooping

Corrupted eMMC NAND memory or thermal degradation under the BGA system-on-chip. Reflashed with factory firmware or re-balled with leaded solder.

T-Con Board / Display Artifacts

Ghosting images, negative colors, or vertical bars traced to T-Con timing controller ICs or level shifter MOSFETs.

Frequently Asked Questions About LG TV Repair

Do you replace only burnt individual LEDs or the full strip set?

We always replace the entire array of LED strips together. Patching a single diode leads to uneven lumen output and causes neighboring aged diodes to fail within weeks. Replacing the entire set guarantees uniform brightness and longevity.

Can physically cracked TV screens be fixed?

Physical glass fractures or internal liquid crystal leaks cannot be repaired; they require a brand new panel module, which often approaches 75% of the TV’s retail cost. We always provide honest guidance so customers don't waste funds on irrecoverable broken screens.
