FAQ

Will I learn how to remove a matrix from an LCD TV without damaging it? I'm interested in a 49-inch diagonal.

Yes, you can learn how to dismantle, install a 49-inch LCD matrix. The complexity at this stage increases starting from the size of the TV diagonal of 47 inches.

Will I be able to repair the TV power supply myself after completing the courses?

Yes. Since the training program has a section where, in practice, the repair of a power supply unit at the component level is considered. What is really relevant today. This will require less restoration costs.

The firmware of the TV has flown, will you teach me how to restore the software?

Software recovery is included in the monitor repair course. Practical lessons with programmers are carried out starting from the 4th day of training. You will learn where to get a working firmware, how to write it to a memory chip.

Will I be able to learn how to solder SMD LEDs on a ruler?

In the hot air soldering station, you will be soldering the LEDs. And also master the technology of adjusting the lenses to eliminate glare on the TV screen. You will learn how to properly mount LED lenses on a ruler.

Buttons on the remote control partially do not work, how can I fix it?

In the course you will learn how to repair remote controls of different models. Including disassembling the remotes without damage, restore non-working buttons. And also solder conductive tracks under a microscope.

I received a TV after another SC with an inoperative backlight unit in the service. I diagnosed the backlight, it turned out to be working. The backlight driver is damaged. Will I learn how to solder chips in a TSOP package?

During training, you can not only unsolder the backlight driver, but also diagnose it using a multimeter. Learn about the interchangeability of microcircuits.

The TV turns on, reacts to the remote control, there is a soundtrack, the matrix backlight is visible (light gray background), while there is no image. Where to start diagnostics?

During the course on repairing TVs, you will study the structure and operation of the matrix, the nodes of the formation of various voltages for its operation. Diagnostics can begin with checking the supply voltages of the matrix. After that, check for a signal from the timing controller to the display connector. Check the reliability of the connection of the connector. Then you can repair such damage yourself.

There is no sound on the LCD TV. The adjustment scale on the screen runs from minimum to maximum values. I checked the speakers, they are working properly. ULF is working properly. But there is no sound, there is also no sound through the earpiece. What to fix?

It is necessary to check the feedback and supply voltages at the ULF. Make sure that the isolation capacitors between the speakers and the microcircuit are in good condition. Solder the ULF microcircuit, check the integrity of the strapping. Make sure that digital or analogue signals are being input to this amplifier, depending on your TV model. In this course, the existing malfunction, methods of elimination will be described in detail. You will not have any questions with the elimination of such a breakdown in the future.

After turning on the TV, everything works fine. There is an image, soundtrack, picture quality is good. After a short time of work, about 5 - 7 minutes, color distortion begins. The image becomes negative, and then one color is set, the picture is not visible. How to proceed?

In case of such a malfunction, it begins by checking the supply voltages of the Gamma corrector. If voltages are present, check the output voltages, from minimum to maximum, on this microcircuit. Be sure to make sure that the matrix is ​​in good working order. When examining motherboards, let us examine in detail the sequence of forming image signals on the TV screen. Algorithm for eliminating this defect.

There is no image on the monitor from the left edge to the middle, while the second part of the screen is working properly. Can this malfunction be eliminated?

This defect occurs when various components of the monitor are inoperative. It is important to make sure that there are voltages supplying the monitor display, if they are absent, check the voltage from the power supply and stabilizers. Check if SMD capacitors are in good condition. On the TV repair course, you will learn how to identify and eliminate such defects.

The client decided to independently repair the backlight in his TV. Having seen enough videos on YouTube, while dismantling the matrix, I tore the train from the bar. Is it realistic to restore it?

If the plume is torn off the matrix glass, then it is not possible to repair the damage without special precision equipment (the price of the machine is very high and the procedure is not cost-effective (1-3 dies per year). you will learn the recovery process by taking a course on repairing monitors.
