Everything you need to know before booking a diagnosis

8 questions answered Verified & updated
The cost to fix All-in-One Touchscreen Not Working in Nariman Point varies by all-in-one PC model and severity. Xigox charges ₹350 for inspection — refunded if you proceed with the repair. A transparent written quote before any work begins. You're never charged until you approve the repair — no hidden fees, ever. Customers across Nariman Point (400021) enjoy priority same-day scheduling.
Xigox repairs All-in-One Touchscreen Not Working on Apple, HP, Dell, Lenovo, Asus, Acer, MSI, Microsoft and Samsung, and more. Our engineers are trained on brand-specific procedures and we stock genuine-grade parts for the most common models, so most repairs in Nariman Point are completed the same day. Customers across Nariman Point (400021) enjoy priority same-day scheduling.
It depends on the age and value of the all-in-one PC. As a rule, if the repair costs less than a third of a comparable replacement and the rest of the hardware is healthy, repairing is worth it. After the inspection we tell you the honest repair cost and what a replacement would run, so the comparison is yours to make — we do not push a repair that is not worth doing. Customers across Nariman Point (400021) enjoy priority same-day scheduling.
No. For any all-in-one PC that still powers on we take a full backup before touching the hardware, and for units that do not, we attempt recovery before repair. Your data is never accessed beyond what the repair requires, and nothing is copied off-site. Customers across Nariman Point (400021) enjoy priority same-day scheduling.
For part replacements our technician works at your address in Nariman Point. All-in-One Touchscreen Not Working that traces back to the board needs microscope and hot-air rework, so that job comes to the lab — with free pickup and drop either way. We tell you which category yours is before you commit. Customers across Nariman Point (400021) enjoy priority same-day scheduling.
You bring it straight back. The same fault inside 90 days is covered under warranty — no second inspection fee, no diagnostic charge, no argument. Our re-repair rate runs under 2%, but the cover is there in writing precisely so you do not have to rely on that number. Customers across Nariman Point (400021) enjoy priority same-day scheduling.
We use OEM or OEM-grade components and tell you which one your quote covers before work starts. We do not fit unbranded aftermarket parts or recycled pulls sold as new — part quality is the single biggest factor in whether a all-in-one PC repair lasts, so it is not somewhere we cut cost. Customers across Nariman Point (400021) enjoy priority same-day scheduling.
That is what the ₹350 inspection is for. Symptoms overlap constantly — the same visible behaviour can come from three different components. We test rather than guess, then show you what we found before quoting. If the actual fault turns out to be something cheaper, the quote reflects that. Customers across Nariman Point (400021) enjoy priority same-day scheduling.
