Why the tablet does not work. Weaknesses of tablets, or what most often breaks
Lovers of gadgets often face the problem - "there is no image on the DELL tablet". Because of this, some people are in a hurry to throw away or change the tablet, without thinking that it is faster and cheaper to fix the breakdown. At the Service Center, engineers will restore the tablet image quality in 2–4 hours (depending on complexity). The operator coordinates the cost and scope of work with the customer at the stage of registration of the application. Ask SC employees about current discounts and promotions. More about breakdown and prevention:
- No contact;
- White screen;
- System crash;
- Service Center recommendations.
If there is no picture on the DELL tablet, pay attention to the power supply. In some cases, the problem lies in a rapidly discharging battery, a breakdown of the power controller or the connector where the wire is connected. Due to the unstable voltage in the network, while recharging the DELL tablet, the microcircuits burn out, and the image disappears.
The screen backlight circuits are responsible for the power supply of the screen - datasheets, connectors, stabilizers, coils and other elements. A typical problem that there is no image is that capacitors are burnt out (more reliable silicon ones). SC engineers are qualified to replace parts or re-solder contacts.
No contact
Has the screen loop gone? Or maybe the contact in the charging cable is missing? This, in turn, leads to loss of the image on the tablet, color distortion. In such cases, change the VGA or DVI cable, or reconnect the lost cable. The original component will be picked up at the DELL Service Center. If this does not help, pay attention to the work of the video card. Better yet, as soon as the “no image” problem appeared, contact the DELL SC in the current region for diagnostics (fortunately, it is free).
White screen
In addition to being flooded with liquid, a broken matrix, the north bridge, or a video card, it may be inner memory... SC engineers will carry out diagnostics. If necessary, they will dismantle the microcircuit and reflash it on the programmer, and then return the DELL tablet to a working state, check the presence of the picture.
One of the most common reasons that there is no image on a DELL tablet is the inadequacy of the matrix. In this case, the basic input-output system of the tablet (Recovery menu) produces errors in text format or the picture has a reddish tint, or the picture simply does not. The unsuitability of the matrix on the tablet is indicated by a decrease in brightness. Such troubles are caused by a factory defect, a broken screen, dust getting between the glass and the sensor, flooding with liquid or other deforming damage to the DELL tablet.
System crash
When there is no image on the DELL tablet, but it audibly turns on and works, you can suspect a software failure. Chaotic attempts by a user not versed in technology to set the desired settings sometimes lead to unexpected consequences - the Recovery menu gets lost - there is no image. Unlicensed or illiterate firmware, viruses or a factory defect are the reasons that, having found out, the engineers of the Service Center recommend reflashing the DELL tablet.
If there is no image on the DELL tablet, experts recommend visiting Service center... Considering the variety of reasons, order a diagnostic service. In the presence of repair work, it is free. Image restoration cost depends on model and complexity. Do not disassemble the DELL tablet yourself: this will exacerbate the problem, and you will no longer be able to apply under the factory warranty. Cooperating with the official DELL SC, the customer receives a warranty up to 3 years, original new components, free diagnostics and delivery, as well as promotions and discounts. You can order a call or leave a request for image restoration on a DELL tablet via the website or by phone.
Why won't the video open on my tablet? Sometimes, users are faced with problems of a different nature. So, MID may not support some types of files, not play videos online. Sometimes the movie starts, there is sound, but there is no picture. It often happens that the video slows down or artifacts of various kinds appear. Let's figure it out.
Why doesn't the tablet show online video?
Watching online videos requires a specific technology. A few years ago, flash technology was considered practically the only one. Now there are many alternative solutions. In most cases, installing advanced browsers helps. These include UC and Dolphin browsers, a full version of Opera. By the way, Flash technology has eaten HTML 5. Resources are built in such a way that they reproduce video content with their own capabilities in a browser or special. applications (such as You Tube or Vimeo).
While Flash is outdated, its absence may explain why the tablet doesn't play videos on the Internet. Unfortunately, you won't be able to download the flash player from the Market. Now there are many fake applications that are not recommended to be installed. You need to download the flash player from a trusted resource and install it on the gadget, having previously enabled the option to install third-party software solutions in the settings. Do this in the parameters, in the "Protection" menu.
Why movies from tablet memory do not open
There is no specific problem here either. To find out the reason, you need to try different options, solving the problem. The very first is the problem with the player. While the default player is better as a power saving feature to fully utilize the hardware capabilities, an additional third-party player should be installed. Fortunately, they do not take up much space. Among the players, we can recommend MX player, HD VP, Joe VLC Player.
The reason that the video does not work on the tablet may be the lack of certain codecs to support the formats. Codecs are downloaded, as a rule, for a specific player. Information about this can be found in the player itself, which will recommend the required version. If you could not find a recommendation, write in the App Store the name of the player and the architecture of your processor. For example, ARMv7. Install codecs. Everything will start working even without a reboot. The complete exceptions are Windows Gadgets, where a codec pack fits all programs and multiple packs can create a conflict.

Other problems
There are more minor problems. For example, why the video does not play on the tablet, but there is sound (if not -). This usually happens when you play files over 1 GB. Here, the problem is often hidden in the way the file is processed - hardware or software.
Hardware processing uses the power of the processor and video accelerator. The good thing is that MID is less overloaded, less battery power is spent. But, sometimes the hardware capabilities simply do not cope with the tasks. In this case, you need to switch the processing method to software.
Another point explaining why video slows down on a tablet. Perhaps the logs and cache of the device are clogged - clean. Install programs to clean the device (Clean Master, CC Cleaner) and clean the device before watching a video. For the most part, weak devices are swinging. By the way, this can explain the appearance of various artifacts.
If you have problems watching live channels, install the SopCast app. True, this is not IP TV, but it is possible to download playlists, create them yourself, etc.

Tablets appeared in ours relatively recently, but have already firmly entered the usual way of life. Such devices are produced by many manufacturers and have their own specific characteristics, advantages and disadvantages. But, despite the abundance of models and manufacturers, most of the breakdowns that sometimes happen with tablets are similar to each other: so, even repairing an iPad new can be somewhat similar to repairing some other tablets, requiring a professional approach. Consider what are the most popular breakdowns that can happen to the tablet of each of us and their causes.
Mechanical damage
This group of defects is often formed in tablets, and the cause is most often a fall or impact. In some cases, only part of the device's case suffers, without touching the heart of the tablet - its electronics. As a rule, users prefer to deal with such a defect on their own, and various improvised means help them in this: covers, stickers, etc. However, it may also happen that as a result of the fall, the electronics also suffer, then it will no longer be possible to cope on its own, and the repair professionals will have to carry the device.
Broken screen
The screen often suffers in tablets, and the reason for this is inaccurate use of the tablet, falling, bumps and other pressure. Although one cannot discount the fragility of the screen, which does not withstand high pressure on him. If the screen is damaged, both the matrix and the sensor may become unusable.
The device does not turn on
When the tablet does not turn on, you can suspect several reasons at once, but all of them, as a rule, are not difficult to fix. So, the problem may be the bootloader is not working properly. If this is true, then the tablet should turn on if you hold the power button longer than usual - up to 15 seconds, or if you press the emergency reset button. If this does not help, then most likely the problem is in the power supply. In this case, you can test the device by connecting it to the network and turning it on. The problem may be caused by improper operation of the power controller, then a simple replacement can help.
Missing sound
Such a breakdown is common, but the reasons are very diverse, which determines the complexity of the repair. So, in the simplest case, to eliminate this problem, you just need to adjust the sound channels and volume. A more or less advanced user can cope with such a task. The reason may also be a faulty headphone jack, which leads to the fact that the user does not hear the sound, or hears it somewhat changed. However, the most terrible reason for the loss of sound is different - a malfunction of the sound device. In this case, the repair of the device will be difficult, which translates into its high cost.
Missing image
The reason for the absence of an image on the tablet screen is most often a problem with the matrix. In order to check and confirm this assumption, you can connect the tablet to another device that is capable of displaying an image, such as a TV. When you see the picture from the tablet on the TV, you can finally confirm the problem with the matrix.
Inability to connect to the network
Often, tablets are unable to establish a network connection such as Wi-Fi. And often the reason for this is incorrect settings or incorrect firmware of the device. Therefore, the correct setting of the tablet, and sometimes a return to the factory settings, can cope with this problem. However, sometimes the matter can be much more serious: in the event that, for example, wi-Fi module out of order.
Touchskirn does not respond
This problem occurs when there is some kind of malfunction in the device itself or in its software. As a rule, such a problem is eliminated after the device is asked again, if, of course, the problem was related to software... If the problem is in the device itself, then the reason may be, for example, the touchscreen cable disconnected from the motherboard.
Of course, other types of breakdowns may appear, but it is still recommended in order not to make the device even worse by your attempts to do the best, take it to a qualified repair.
