1. Visual inspection of the body, connectors, screen, and cameras for mechanical damage or signs of moisture.
2. Hardware check using a motherboard tester (from brands like OssTeam, Qianli) — reading error codes, monitoring power on the VCC Main bus.
3. Analysis of power systems — checking the battery, U2 controller, charging circuit (Texas Instruments, Dialog Semiconductor).
4. Software diagnostics — checking for malware, freezes, boot loops, firmware issues.
5. Display module testing — identifying dead pixels, unresponsive areas, touch lag.
6. Audio analysis — evaluating the performance of microphones, speakers, 3.5 mm/Type-C ports (if necessary — checking the audio codec).

1. When the battery drains quickly even after a full charge.
2. After a software update, when the device started "glitching" or freezing.
3. After a drop or water damage — not all damage is immediately visible.
4. If the tablet does not turn on at all or the screen remains black.
5. If Wi-Fi or Bluetooth disappeared — the problem could be in the module or the antenna.

• Free tablet diagnostics in Prague — you risk nothing, you simply find out what the "bug" is, and only then decide whether it's worth repairing the device.
• We don't guess randomly — Technofix employs masters who understand tablets. You get the result quickly.

1. The tablet doesn't see the camera – the system doesn't recognize the module, the camera "disappears" in apps.
2. The tablet camera doesn't focus – autofocus works intermittently, photos come out blurry.
3. Poor photo quality on the tablet – colors are distorted, the image is dark or has "grain".
4. Physical damage – cracks on the module glass, moisture inside, consequences of impact.
5. Glitches after updating the operating system – "bugs" in drivers, conflicts between the firmware and the camera.

1. Replacement of the tablet's front camera – most often suffers from drops or dust getting into the lens.
2. Repair of the tablet's main camera – includes testing focus, controller microchips, and replacing the sensor.
3. Software correction of the camera's operation – reflashing, updating drivers, restoring system components.
4. Complete diagnosis free of charge when ordering a service – in a quarter of an hour, we determine whether it's worth replacing the camera or if a cheaper solution is possible.

1. How much longer are you willing to put up with a camera that "can't keep up"?
2. Is it worth settling for photo quality worse than an old phone's?
3. Why not replace the camera now – and start using a fully functional tablet today?

1. The tablet won't turn on after the fall — possible problems with the power board, broken cables, damaged microchips.
2. Cracked screen or glass — the touch layer may work partially or not respond at all.
3. Cracks on the body — this is not just a cosmetic defect, but also a risk of moisture ingress.
4. Problems with sound, Wi-Fi, or the camera — there might be a shift in modules or damage to contacts.
5. Data loss — when the device won't turn on, but you need to retrieve photos or documents.

1. We accept the device and perform a quick diagnostic within half an hour — to understand more specifically what is troubling your tablet.
2. We explain the essence of the problem and state an honest price with deadlines.
3. We restore the body: replace cracked parts with original or sturdy premium analogues.
4. If there are problems with the board — we solder, replace controllers, NAND or CPU, but only when it is justified.
5. If the tablet doesn't turn on, we extract data from eMMC or UFS chips using special equipment.
6. At the end, we check all functions — Wi-Fi, Bluetooth, camera, screen, and battery — so everything works like new.

• screen is unresponsive or spots/stripes have appeared;
• tablet doesn't charge or heats up during charging;
• device doesn't turn on at all;
• burning smell or unusual sounds are heard;
• Bluetooth or Wi-Fi doesn't work;
• it freezes on the startup screen or restarts on its own.

Replacement of tablet charging connector in Prague: Technofix — fast and reliable repair

Tablet stopped charging or only responds after prolonged jerking of the cable? Perhaps the charging connector has malfunctioned.

Damage to the USB port is one of the most common reasons for contacting the Technofix service center in Prague. We quickly, accurately, and at an adequate price perform repair of the tablet charging socket in Prague, regardless of the brand or type of connector.

When is a tablet charging port replacement needed?

1. Tablet does not see charging, even when using the original cable.
2. Charging cable "has play" or only charges at a certain angle.
3. Port has physical damage, cracks, or too loose fit.
4. No data transfer via USB.
5. Charging is too slow or does not start at all, despite a working adapter.

Which connectors do we replace?

At Technofix, we work with all current types of connectors used in modern tablets. Most often it is micro USB, which is still found in Lenovo Tab M7 or M10 series, as well as in budget models of Huawei, ASUS, or Prestigio. Type-C ports are also common, used in Samsung Galaxy Tab, Xiaomi Pad, Lenovo P-series, and some versions of iPad.

Proprietary connectors require a special approach, such as those in Microsoft Surface or older Apple devices with Lightning connectors. For each case, we select parts with 100% compliance with the standard, often from brands like Foxconn, Molex, or Amphenol — this allows us to maintain operational stability and repair longevity.

How does the repair at Technofix proceed?

1. Device diagnostics — we check the connector, power controller, battery, and related circuits.
2. Removal of the old port — we perform disassembly under a microscope, using a temperature-controlled soldering station.

If the connector is soldered to a multi-layer board (for example, in Samsung or Xiaomi), we use low-temperature solder and Amtech flux to avoid overheating the layers and damaging surrounding components. In cases of complex geometry, where the port is also mechanically secured, special tools are used for localized heating of the connector body.

3. Preparation of the landing zone — we clean, restore contact traces, and if necessary — reinforce the board.
4. Installation of the new socket — we install the component, check the soldering, and secure it according to factory standards.
5. Final testing — we check charging, voltage stability, data transfer speed, and thermal regime.

Additionally, we check for voltage drop under load and test the port for wear resistance — simulating up to 100 connect-disconnect cycles to finally ensure contact reliability.

Which tablet brands do we service?

Technofix is a universal computer service in Prague that services tablets from practically all manufacturers. We are often approached with Lenovo devices, including Tab M, Tab P, Yoga Tab — we are an informal Lenovo tablet service center in Prague, where we know the specifics of their power board well.

We also repair Samsung Galaxy Tab (all series), Huawei, Xiaomi, ASUS, Amazon Fire, Prestigio, and other brands.

For Apple iPad, especially versions with USB-C, we perform complex connector soldering. We work with both modern models and those that are no longer officially supported.

We work especially carefully with models where the connector is located on a sub-board connected by a flex cable — for example, in Lenovo Tab M10 or Huawei MediaPad. In such cases, it is important not only to replace the port but also to check the integrity of the flex cable and contact group. We also always check the charging controllers (e.g., TI or Qualcomm) to rule out hidden defects.

Why is it important not to delay? Problems with tablet charging in Prague often start with small things — a slight play or slow charging.  At Technofix, we will restore your device quickly, carefully, and professionally.

1. The device turns off with 20–30% charge remaining.
2. The tablet does not charge or charges very slowly.
3. The device's body is deformed – possible swelling of the power cells.
4. The device overheats while connected to the charger.

1. Diagnostics. We connect the tablet to special equipment and literally "listen to its pulse": we check how much life is left in the battery, how the power controllers, cables, and ports are working. It's like a medical check-up for your device – quick, accurate, and painless.
2. Disassembly. We work with tools that resemble surgical instruments more than anything – no scratches, no cracks, no risk to the display. We open the casing delicately, like a page of an old book, to get to the heart of the tablet – its battery.
3. Installation of a New Battery. We use only verified modules – LG Chem, SCUD, BOE, Samsung SDI – brands trusted by the manufacturers themselves. They have multi-level protection, stable voltage, and a long lifespan. Your tablet will get not just a battery, but a reliable new heart that will work without failures.
4. Testing – after replacement, we conduct checks for discharge, charging, temperature, and power stability.
5. Final Stage – the tablet is returned to the client after a full test and calibration.

• installation of higher capacity batteries (if compatible);
• system optimization (cleaning out unnecessary software, configuring power-saving settings);
• firmware update, battery calibration.

1. Diagnostics — free with repair. First, we carefully examine the problem under a microscope — both literally and figuratively. Is a full module replacement really necessary, or is updating just the touch sensor sufficient? We don't remove anything extra if it can be saved — that's our principle.
2. Tablet Matrix Replacement will be needed if the screen starts "drawing" strange colors, spots or horizontal lines appear, or the image looks like it's been washed with watercolor.
3. Tablet Touch Sensor Replacement — when there is an image, but the touch sensor doesn't work or responds incorrectly.
4. Calibration and Testing — after replacement, we обязательно check all functions so the device works like new.

• Original Parts – we install only reliable components, for example, LG Display, Samsung Display, or BOE displays, depending on the brand.
• Warranty on all work – up to 6 months.
• Transparent Price – no "hidden costs". You know the cost of tablet screen replacement in Prague in advance.
• Fast Repair – 80% of replacements are completed in 1-3 days.
• Convenient location of the Technofix service center in central Prague.

1. Is it possible to replace the tablet screen yourself? It is, but the risks are high: battery damage, loss of sealing, ruined cable. At Technofix, we have the necessary tools, anti-static protection, and professional skills.
2. Does the battery need to be changed along with the screen? Not always. If during the replacement we notice a swollen battery — we will inform the client and offer a comprehensive repair option.
3. Is data preserved after screen replacement? Yes, replacing the display does not affect the data in the device's memory. We still recommend making a backup before the repair.
