Expert Chip-Level Motherboard Diagnostics in Mumbai
The mainboard (motherboard) is the brain of your Smart, Android, Google, or Fire TV. It regulates video signal processing, network connectivity, HDMI routing, audio amplification, and system memory.
When an authorized brand center tells you: "The motherboard is dead; pay ₹8,000 to ₹14,000 for a new board," they simply lack the micro-soldering skill to repair individual chips. At our Prem Nagar, Goregaon West workshop, our certified electronics engineers repair the original motherboard down to the IC level, saving you up to 65% of the total expense.
Motherboard Problems We Specialize In
- TV Stuck on Boot Logo: The TV turns on, shows the brand logo (Samsung, Mi, Sony, LG WebOS, Android), freezes, and continuously restarts in a bootloop. (Fixed via eMMC memory IC re-flashing or replacement).
- No HDMI Signal Detection: All HDMI ports show "No Signal" after an electrical thunderstorm or cable hot-plugging. (Caused by blown HDMI ESD protection diodes or HDMI switch IC).
- Wi-Fi & Bluetooth Disconnected: Smart TV cannot detect home Wi-Fi or disconnects every 5 minutes. (Wi-Fi module chip replacement or 3.3V LDO regulator repair).
- Remote Control Not Responding: IR receiver section circuit or processor communication port failure.
- Constant Restarting Every 30 Seconds: Power management IC (PMIC) or RAM chip thermal instability.
Equipped with High-Precision Micro-Electronics Benches
Motherboard repair requires precision thermal profiling to prevent board warping. Our workbench features:
