HYUNDAI H-LED24V6
General repair guidelines for TV LCD LED
HYUNDAI H-LED24V6, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. In some cases, visible external damage to the elements can indicate the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of electronic circuit nodes. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
In the case when the H-LED24V6 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink lights and does not show any signs of operability, the power supply module is probably defective in this case. If it is serviceable with such manifestations, it is necessary to check the stabilizer (converter) of the processor power supply on the motherboard. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is cut off in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip can also cause a breakdown of the power switch of the converter.
If the HYUNDAI H-LED24V6 does not have an image, but there is sound, the backlight LEDs of the M240HW01 panel or their power converter may malfunction. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and connectors.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
If the motherboard CV182L-C 2AJ1111A H is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
In some cases, they require checking or replacing (if necessary) the elements of the MB board (SSB) - Flash 25Q32. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
Before changing the tuner CDT-3SP512-37, if it is not possible to tune to television channels, make sure that there are supply voltages, including varicap power (30-33V), which must be measured on the corresponding tuner pins.
Attention to the owners! Attempts at self-repair of the HYUNDAI H-LED24V6 TV are not recommended by the manufacturer and can lead to serious negative consequences!
FIRMWARE FOR SPI FLASH -----------> HYUNDAI H-LED24V6, Main: CV182L-C, Panel M240HW01
In case of failures in Winbond's SPI FLASH software, sometimes they can temporarily restore their functionality after temperature exposure, for example, heating with a soldering station or a lighter. Often this is enough to be able to read the regular software content. After that, the chip should be replaced with a new one.Repair MainBoard
The appearance of the MainBoard CV182L-C is shown in the figure below:
The CV182L-C motherboard uses the MST6M182VG processor, combined with a scaler and installed using the BGA technology.
It is advisable to start this type of MainBoard repair by checking the voltage converters and linear stabilizers necessary to provide power to the processor nodes: 1.2V, 2.5V, 3.3V. Check the power supply of the 5V or 12V LCD panel, depending on the type of panel used, it is advisable directly on the LVDS connector. If, in the presence of the necessary supply voltage, the TV does not exit Stand-by mode, does not respond to the remote control and control buttons, the SPI Flash software should be updated.
CV182L-C can be used in TVs:
HYUNDAI H-LED24V6 (Panel M240HW01), HYUNDAI H-LED19V6 (Panel M185B3-LC1 Rev.C1), HYUNDAI H-LED19V16 (Panel LM185WH2), HYUNDAI H-LED15V6 (Panel LP156WD1 (TL)(A1)), HYUNDAI H-LED22V6 (Panel M215HW03 V.1).
Main features of the HYUNDAI H-LED24V6 device:
Installed matrix (LED-panel) M240HW01.
The required supply voltage for all nodes of the HYUNDAI H-LED24V6 TV provides a switching power supply.
MainBoard - the main board (motherboard) is a CV182L-C module, using Flash 25Q32 chips and others.
The tuner CDT-3SP512-37 provides the reception of television programs and tuning to channels.

Attention! The M240HW01 panel of the HYUNDAI H-LED24V6 LED TV 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!
