There can be many reasons for the TV malfunction. In some cases, you can repair the equipment with your own hands, in others you will have to contact the service center. It is better to repair and customize BBK TVs according to the accompanying instructions. Or at least read the articles on this topic in advance to know about the features of a particular model.
BBK TVs malfunction and fix
In order to repair BBK TVs, first of all, you need to understand the causes of the malfunction. There can be quite a lot of them, so if you don’t have experience with television equipment, it is better to make a diagnosis in a service center. This is especially true if the device is on warranty.
Does not turn on
If the tv set is not on the lights and when you try to turn it on from the remote or the panel, there is probably no reason for the lack of electricity:
- Check to see if there is electricity in the house.
- Check the plug’s connection to the socket.
- whether the integrity of the cord is broken.
If bbK LEM1968DT is not turned on at all, the lights don’t light up, you should start looking for a reason from the power module. First, check the secondary output voltage, if it is not present, check for short circuit diode and keys of converters. In the primary chain, the network fuse may be damaged.
In case the light on the TV panel is red, but it itself is not turned on there are several options. If when you try to turn on the TV remote control the lamp continues to glow red, the green does not light up, then it’s in the remote. With a burning indicator, we can conclude that there are no problems with electricity and power supply. Here’s how to solve the problem:
- Replace batteries
- replace the remote control if there are cracks and damage on it.
In this video, you’ll learn more about setting up the TV: If the BBK TV is not turned on with the control panel, there may be several reasons:
- The protection that protects against voltage swings has worked. You can try to remove the fork again and insert it back into the socket.
- It is less likely that the cause may be a malfunction in the power supply. A visual inspection of the parts will help to identify the failures.
- Malfunctions in the system board, a power chain violation.
- Because of power problems, the chip flew.
If you try to turn on the light on the bar lights up green, but nothing appears on the screen, there may be the following reasons:
- software malfunction, broken sequence of commands, you can cope with the situation only by re-opening the software and firmware;
- Incorrect system board work
- damage to the LCD matrix.
Flashing the indicator can indicate a breakdown of any of the TV systems. Check in this case you need all the elements of the TV circuit, starting with the power supply.
The sound is gone
If the BBK device has a sound problem, there may be several reasons:
- If there is no sound from the speakers, but when the headphones are connected, the reason is the speakers themselves or the contacts;
- Incorrect settings
- The sound card was burnt out.
- Mute bus malfunction
- The breakdown of the motherboard;
- the firmware flew.
Some users mistakenly believe that their TV receiver needs to be repaired if a “no signal” message appears on the screen when they turn on. The reasons for this phenomenon, both on BBK TV and on the models of other firms, may be as follows:
- Interference on the transmission line or bad weather conditions;
- Preventive work at the provider;
- You need to set up the set-top box correctly, at the beginning of the tuner, it should be rebooted, perhaps it will help to fix the problem;
- Malfunctions in the receiver that require its repair;
- The tuner needs to be re-stitched.
Reasons why there is no signal, just a few
To know for sure that it is in the receiver, and not in the TV, you can temporarily install a serviceable tuner.
The fact that the TV is faulty lighting, you can judge, if on the turn there is a barely noticeable picture. The reason may be:
- burnout of lamps (at LCD TVs) or LEDs (lcd);
- Food doesn’t get to the lights.
In the first case, it is necessary to replace burnt lamps or LED. If the reason for the failure of the illumination in its power, the tester should check the voltage of the chip and transistors in the transformer chain, as well as the transformer itself. All faulty parts change.
In cases where there is a sound when you turn on, and the image is gone, or first appears, and then disappears, the reason is not in the power supply. The most likely option for missing a picture on a TV is a problem with the backlight (nutrition, the health of LEDs or their connection). At the same time, the volume is adjusted in the same mode.
For the LED TV BBK it remains to open the panel and separately check each LED multimeter. It is dangerous to check the consistent connection of LEDs at home without special equipment.
Turns on and off immediately
There are situations when the lamp can light up green, but then again burns red and nothing happens, so the processor is healthy and able to send the command to be turned on. But one of the blocks this command does not perform, so the light bulb goes out.
- Also, a modern TV with internet access can run software updates or try to connect to the Internet.
- The presence of dust on the boards prevents electricity from passing through them.
- Due to problems in the power supply, the TV can also spontaneously turn off after an indefinite period of time.
If when you connect to a new antenna, cable, tuner when turning on the TV is hovering, you need to understand the settings of the chosen type of connection. And also, check the integrity of all wires and cables. Maybe it’s just interference on the line.
Set up bbk TV for TV reception
Repairing the BBK TV receiver is not always necessary. Sometimes it’s enough to do all the settings correctly. To do this, you just need to refer to the attached instructions.
Setting up channels
Before you start setting up channels from the remote control, you need to connect the BBK TV to the source of the digital, cable or interactive signal (cable, receiver, insert a map to receive digital television).
In the Menu section, the Channel includes automatic or manual channel search mode. The capabilities of modern TVs then allow you to edit the found channels, set up the file system and check the quality of the signal.
How to sew a BBk TV with a flash drive
If you don’t need to repair your BBk TVs, you just need to re-read it from the flash drive. Here’s how to stitch a BBK TV to install new software on it:
- On the manufacturer’s official website, learn about the latest versions of the software for a particular model.
- Download the current version to your computer, unzip the firmware file and copy it to the USB carrier.
- By connecting the flash drive to the connector on the TV set, call the main menu from the remote control, find the “Software Update” tab in the Channel tab, click OK, and start the update by selecting the Left key.
- Once the software is downloaded, the TV will reboot itself.
Replacing the lamp light on the BBK TV is not an easy thing, but quite doable. To do this, you need to prepare several suitable lamps, gloves, screwdrivers, stationery knife.
To get to the lamps themselves you need to put the TV monitor down on a soft surface and remove the protective box. Get the whole LCD module, glue the protective film with the decoder, and the matrix itself is carefully, so as not to damage anything. If you damage the film, it will be impossible to restore the entire matrix to work.
By freeing the lightlight from other elements, you can start replacing the lamps. If you could not visually identify the burnt-out lamps, you will have to install a serviceable lamp on all the order of place. Or identify a malfunction with a device that creates little resistance through an inverter.
Changing all the faulty elements, assemble the design in reverse order, connect the TV to the network, if there is no image – give time to warm up the new lamp.
It is not always necessary to repair the BBK TV in the service center. Small breakdowns, firmware or setting of the device can be carried out independently.
