FAQs — Dell OptiPlex 5400 AIO All-in-One Backlight Failure in Dadar

Everything you need to know before booking a diagnosis

8 questions answered Verified & updated
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. We've been serving Mumbai City district for over 15 years.
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. We've been serving Mumbai City district for over 15 years.
For part replacements our technician works at your address in Dadar. All-in-One Backlight Failure 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. We've been serving Mumbai City district for over 15 years.
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. We've been serving Mumbai City district for over 15 years.
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. We've been serving Mumbai City district for over 15 years.
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. We've been serving Mumbai City district for over 15 years.
Usually not for long. Left alone, most faults of this kind put stress on neighbouring components and turn a contained repair into a board-level one. If you cannot bring it in immediately, tell us the symptoms on WhatsApp and we will tell you honestly whether it can wait a few days or should be powered down now. We've been serving Mumbai City district for over 15 years.
Yes — Xigox specialises in All-in-One Backlight Failure across Dadar. Our certified technicians diagnose and fix the problem efficiently, using OEM-quality parts and backed by a 90-day warranty. Free doorstep pickup is available in Dadar — call or WhatsApp +91 74997 61196. We've been serving Mumbai City district for over 15 years.
