From a single device to a whole office, all handled the same way

The client moved into a new office in Linkong Park, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.

The same problem had been handled twice elsewhere without a fix. We re-diagnosed to find the real cause, and after repair it stayed stable for a week of observation.

The client needed to operate normally during the day, so we came after hours. Several staff worked in parallel and finished testing and cleanup before closing.
What you most want to know about on-site service in Tianshan
The sooner the better. Power off and don't keep powering it on; after stripping and de-corrosion most can be saved. Even with heavy board damage, drive data can usually be recovered separately.
On-site fixes are done immediately; rework-station jobs usually take 1–3 working days, and we give an estimate when we take it on.
Yes. Judgment and diagnostic depth differ. An independent diagnosis costs nothing extra: component repair if possible, board replacement only if genuinely necessary.
On-site diagnosis is free; you approve the quote before any repair.
Anything involving storage is backed up or imaged first; suspect drives are assessed before work.
No charge if it can't be fixed for technical reasons, and we explain the situation and options.
Describe the device and the symptoms; our technician brings the right tools and common parts. Diagnose first, quote after, and repair only once you approve.
