DEXP TV malfunctions and repair

DEXP TVs do not end up in repair shops very often - this brand has been sold in Russia for only a few years. The main problems arise with electronic "stuffing" and Smart systems. Sometimes the source of trouble is the user himself, who violates the operating rules or who does not understand enough about the control of the equipment, which is why it does not respond to the remote control. You can understand why the DEXP TV does not enter the Play Market (writes that the device is not registered), as well as learn more about how to eliminate other failures, after examining the causes of the malfunctions.

Many of the problems with DEXP TVs are not original. It is worth considering common breakdowns and failures in more detail.

1. DEXP TV does not turn on. It is necessary to check why the device does not work, to clarify whether there is power in the network and the outlet. If the indicator is off, the power supply may be damaged or the device may be disconnected from the mains.
2. The TV does not enter the Play Market. On all Android-based mobile devices, when the Smart TV is turned on, this happens due to a discrepancy between the time and date in the device with real data. Also, there may be no network connection. Sometimes the device is not included in the account if the application or system requires an update to the latest version.
3. Does not show the screen - writes that the device is not registered. This message appears in a dialog box, after which it becomes impossible to use the TV. The problem is related to the defect of the firmware. You need to contact the seller to exchange or return the TV.
4. The device slows down when turned on. In the case of Smart TV, this is normal, the delay can reach 30-40 seconds due to system boot.
5. The equipment does not respond to the remote control. You need to try to change the distance and angle of inclination of the remote control, check for the presence of batteries in the compartment, replace them if necessary. If everything is fine with the buttons on the case, the point is definitely in the remote control.
6. DEXP does not load beyond the logo. This is a fairly common problem that can be solved by replacing the firmware or performing a factory reset.
7. On the screen there is an inscription: "no signal". The antenna may be defective or the receiver may not be connected to the mains. Settings may fail. In the absence of any reaction to the antenna replacement, it is worth checking the TV tuner at a service center.
8. There is no picture, but there is sound. Most likely, the reason is a faulty backlight. Dimming can be local or full. Sometimes a malfunctioning matrix is ​​the cause of problems. Such repairs will cost more.
9. The TV is frozen on one of the channels, does not respond to the remote control. It is worth checking the health of the batteries in the remote control. If it does not help, do a factory reset.
10. DEXP does not work in Smart mode. Applications that require online access cannot be used, but the network connection is maintained. In this case, the first step is to reset to factory settings. If it does not help, you need to contact the service center for diagnostics - perhaps the problem is in the memory chip.

More rare breakdowns are better diagnosed with the assistance of professionals with special equipment.

Repair of DEXP TVs is mainly associated with setting up and adjusting its parameters. For example, the lack of communication with the Play Market can be eliminated by checking and setting the current time and date in the appropriate section of the system. If the failure is due to errors due to incorrect data from the digital network provider, you can select the option to adjust the time according to the Wi-Fi network.

When the TV does not turn on either from the remote control or from the buttons, a possible cause of the problem is a tripped protection against power surges. In most cases, it can be eliminated by simply disconnecting the equipment from the network. After pulling out the plug from the socket, the TV set must be left for 30-60 minutes, and then the power must be restored again. If these measures do not help, the likely culprit is a burned-out board, connector, power supply, or processor.

To solve the problem in which the TV receiver does not boot, you need to:

• turn off the TV with the network button;
• turn on from the remote control and hold down the Prog Down button with an arrow down;
• after booting the Recovery System, wait for the menu to appear;
• do not touch anything until the splash screen appears in the form of a lying robot;
• press the Home button on the remote control;
• find Reset Data in the drop-down menu, select;
• select OK in the new window;
• wait for reboot, reconfigure the system.

Calling a foreman from a service center or an independent appeal to a repair shop is necessary in cases where it is necessary to open the case or perform other technically complex work. Besides, Having experience in repairing electronics, it is worth remembering that any unauthorized opening of the case will result in the cancellation of the factory warranty. Even if the cause of the breakdown turns out to be a defect, it will be impossible to exchange for a serviceable TV.

It is recommended not to carry out any work related to the replacement of backlight lamps on your own. - to access them, you will have to take out the matrix, perform other actions that require precision and care. There are parts inside the machine that accumulate residual voltage. They must be discharged to avoid electrical shock.

Contacting a workshop is recommended in case of such malfunctions as complete damage to the display - it is broken, the matrix is ​​burned out. The power supply unit can be repaired by yourself, but it is better to entrust this work to professionals too. Such breakdowns as failure of a board or a control system necessarily require the intervention of specialists.

It is important to understand that parts for complex household appliances cannot be simply bought... In the service center, their deliveries are organized officially, and repairs will not require cancellation of the warranty.
