General recommendations for TV LCD LED repair
Possible manifestations of defects
- LG 43UK6200 TV does not turn on. There are no signs of operability. The indicators on the front panel do not light up or blink, the TV does not respond to the control buttons.
Usually, with similar manifestations, the defect is caused by faulty elements in the main power supply module EAX67209001. It is necessary to measure its secondary output voltages, and if they are absent, check the power switches (TO-252) and rectifier diodes in the converters for a short circuit.
In case of breakdowns in the secondary circuits of the converter, it can usually work in an emergency mode in a short circuit mode, and with a short circuit in the power elements of the primary circuit, the mains fuse or current sensor in the source of the key is most often cut off.
Breakdown of Mos-Fet switches used in switching power supplies is often caused by malfunctions of other elements, for example, in the power supply circuit of the PWM regulator, in frequency setting or damper circuits, as well as in negative feedback stabilization. PWM microcircuits (PWM) PFC, PWM are usually checked by replacing them with new ones, or knowingly working.
- There is no image, there is sound, it reacts to the remote control. Or the image may appear for a second when turned on and immediately disappear.
A malfunction is usually in these cases most likely in the backlight units of the display matrix. Often the cause of a malfunction is the lack of current in the LED circuit, for example, their open or short circuit, or a violation of the contact connections of the connectors.
To check the LED strips for breakage without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter; a voltage of the order of several tens of volts is required.
- The indicator blinks or is on constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the EAX67872805 motherboard should begin with checking the stabilizers and power converters required to power the microcircuits and matrix. If necessary, you should update or replace the software (software). Repair of the board and replacement of CPU, eMMC, DRAM, AUDIO, DC / DC microcircuits are performed if the necessary equipment and the corresponding element base are available. Failures associated with the use of BGA soldering technologies can be localized by warming up.
If the TV operates normally from external devices, but does not tune to TV channels, the TDJA-G601D tuner may malfunction. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the reason for the inoperability of the tuner may be a software failure.
Owners of the 43UK6200 TV are advised to contact only qualified specialists with the necessary experience for repair! Attempts to repair yourself without the appropriate knowledge and skills can lead to irreversible negative consequences!

Main features of the LG 43UK6200 device:
Installed matrix (LED panel) AC430DGG.
A converter combined with a power supply is used to power the backlight LEDs. TO-252 switches are used as power elements of the LED driver.
The formation of the necessary supply voltages for all nodes of the LG 43UK6200 TV is carried out by the EAX67209001 power module, or its analogs using PFC, PWM microcircuits and TO-252 power switches.
MainBoard - the main board (motherboard) is an EAX67872805 module, using CPU, eMMC, DRAM, AUDIO, DC / DC chips and others.
Tuner TDJA-G601D provides reception of television programs and tuning to channels.

Attention! The AC430DGG panel of the LG 43UK6200 LED TV is an expensive and unreliable element.
Do not allow any impact on the glass and pressure on the screen surface to avoid damage to the LED panel!
It is also unsafe for liquid to spill onto the screen. Sometimes one drop is enough if it drips down the glass onto the cables to make the TV unrepairable.
