We solve the complex hardware faults other service centers reject — diagnosed on the bench, explained to you, and repaired under the microscope.
Comprehensive Ground Resistance (GR) testing on battery connectors, power lines, and boot cable DC supply triggers.
Precise thermal short localization using non-destructive rosin smoke coating and calibrated DC current injection.
Surgical reconstruction of severed or burnt copper PCB tracks under high-magnification stereomicroscopes.
Fixing phones stuck on company logo without firmware flashing, resolving hardware sensor, CPU, and RAM disconnects.
Upgrade your workshop with practical, hands-on coaching. Learn real motherboard fault-finding from an active master technician.

No guesswork, no unnecessary part replacement — just a repeatable diagnostic method refined over thousands of dead boards.
We never charge to tell you what is wrong. You get the fault, the fix and the price before we touch the board.
No inflated part swaps. If a ₹50 capacitor fixes it, you pay for the capacitor and the skill — nothing more.
Every repair is soak-tested on the bench and backed by a written warranty on the fault we fixed.
Component-level work saves motherboards that other shops write off — and saves your data with them.
Visual inspection under a stereo microscope plus a DC power supply test. We read the ampere curve to classify the fault before a single component is removed.
Step 01
Schematic and board-view tracing on ZXW / Bornio, supported by rosin smoke and calibrated voltage injection to isolate the exact shorted line — no guesswork.
Step 02
Micro-soldering, component replacement, BGA reballing or 0.01mm jumper routing, finished with UV solder mask curing for a factory-clean result.
Step 03
Full functional bench test: boot sequence, charging current, network, audio, camera, Wi-Fi and a thermal soak test before the device is handed back.
Step 04

Feedback from people who handed us a phone they had already written off.
“I had written off a Redmi board that two shops rejected. TSR traced a half short on the sub-PMIC line in under an hour and the phone booted the same evening. The diagnosis was explained to me on video — completely transparent.”

Everything about turnaround, data safety, warranty and coaching eligibility.
In most cases, yes. We start with a free visual inspection and a DC power supply test. If the board draws current we can usually trace the fault to a shorted capacitor, a faulty PMIC or a broken power line. You get a clear diagnosis and quote before any work begins — if the board is beyond economical repair, we tell you honestly.
