"It just won't switch on anymore." A completely dead phone is one of the most stressful repairs to face — it usually means the fault sits deep inside the device, on the motherboard itself. Motherboard repair is the most advanced tier of mobile repair we offer, requiring chip-level diagnostics rather than simple part swaps. Here's our full mobile motherboard repair service in Chennai.

Common Signs You Need Motherboard Repair

  • Phone completely dead — no display, no vibration, no charging light
  • Stuck in a boot loop, restarting repeatedly without fully starting up
  • Sudden shutdown after liquid exposure, followed by refusal to power on
  • Burning smell, unusual heat, or visible corrosion near the charging port
  • Phone was working fine, then died suddenly with no clear cause
  • Other repairs (screen, battery) already ruled out but the fault persists

Our Motherboard Repair Process

  • Free diagnosis — the board is inspected under magnification for shorts, corrosion and damaged components.
  • Chip-level testing — power rails, ICs and connectors are individually tested to isolate the exact fault.
  • Quote confirmation — an exact price for the specific IC or component involved, before any soldering begins.
  • Micro-soldering repair — damaged chips are reflowed or replaced using precision micro-soldering equipment.
  • Full functional testing — power-on, charging, display, sensors and connectivity are all verified before handover.
"A phone that's completely dead isn't always beyond saving — in most cases, the fault is isolated to one or two components on the board, not the entire motherboard."

Genuine Motherboard Parts We Use

We only use genuinemanufacturer-grade tested ICs and board-level components — never uncertified duplicates that risk further damage. Every replaced chip is tested for correct power draw and signal integrity before the board is reassembled.

Repair Time

Motherboard repair is the most technical service we offer — most cases are diagnosed the same day, with chip-level repairs typically completed within 1–2 days depending on the fault.

Warranty on Motherboard Repair

Every motherboard repair comes with a 90-day service warranty covering the repaired components and the workmanship, backed by a physical warranty card.

In many cases, yes. If corrosion is caught early, our technicians can clean, reflow or replace affected ICs at the board level and restore normal function.

Every motherboard repair includes a 90-day service warranty covering the repaired components and the workmanship.

A dead phone can feel like the end of the road, but chip-level repair brings back devices that many shops would simply call unrepairable. Don't discard your phone before getting a proper board-level diagnosis from a technician trained for it.
