General repair guidelines for TV LCD LED
Possible manifestations of defects
- HYUNDAI H-LED24V19 does not turn on, the indicators on the front panel do not light or flash. The TV does not respond to the control buttons and the remote control.
The malfunction in such cases should be sought in the elements of the power source - the network voltage converter (AC / DC), which is located on the MainBoard TP.MS18VG.P77 main board. It is necessary to verify the presence of its output voltages and, if they are completely absent, check the power switches and rectifier diodes for a probable short circuit.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM SOT23-6 PWM chips are usually checked by replacing with new ones, or obviously working.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
In most of these cases, a malfunction is detected in the nodes and backlight elements of the LED panel. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can check each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN junction indirectly indicates a LED-a
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the TP.MS18VG.P77 motherboard should be started by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). In cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - CPU: MST3M182VGC-LF-TZ, FLASH: GD25Q32BSIG which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
The malfunction of the R620D tuner is established after checking the software and all the supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
Attention! Users and owners of H-LED24V19 TVs who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

Main features of the device HYUNDAI H-LED24V19:
Installed matrix (LED panel) V240AE1N01-1.
The matrix control uses the Timing Controller (T-CON) 24M09-C07.
To power the backlight LEDs, a converter is used, combined with the main board TP.MS18VG.P77, controlled by the OB3350CP PWM controller.
The power module is combined with the MainBoard and is made according to the flyback AC / DC voltage converter circuit using PWM SOT23-6 microcircuits.
MainBoard - the main board (motherboard) is a module TP.MS18VG.P77, using CPU chips: MST3M182VGC-LF-TZ, FLASH: GD25Q32BSIG and others.
The R620D tuner provides TV reception and channel tuning.

Attention! The HYUNDAI H-LED24V19 LED TV panel V240AE1N01-1 is an expensive and unreliable element.
Avoid any impact on the glass and pressure on the surface of the screen to avoid damage to the LED panel!
It is also unsafe to get liquid on the screen. Sometimes one drop is enough if it flows down the glass onto the cables so that the TV becomes unrepairable.
