General repair guidelines for TV LCD LED
The HYUNDAI H-LED24V15 TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Sometimes, based on visible changes in the components of the device, it is possible to draw some conclusions and determine the direction of further troubleshooting even before the necessary measurements are taken. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
Malfunctions of the power module can be expressed in different ways, for example, the HYUNDAI H-LED24V15 does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
If there is no image when you turn on the HYUNDAI H-LED24V15, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the C240X13-E3-A panel, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
To check the health of the LEDs, as well as contact connections in the ruler circuit, it is necessary to disassemble the panel.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes.
In cases of attempts to repair the JUC7.820.00094330 motherboard, it is necessary to check the operability of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
Board repair and replacement of Cpu: TSUMV59XES-XG, Flash: 25Q32 microcircuits are carried out with the necessary equipment, and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
Remember! Attempts to self-repair by users of the HYUNDAI H-LED24V15 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!
FIRMWARE FOR SPI FLASH -----------> HYUNDAI H-LED24V15, Main: JUC7.820.00094330, Panel: C240X13-E3-A
In case of failures in the software of SPI FLASH microcircuits made by Winbond, they can for some time restore their working capacity after temperature exposure - heating by a hairdryer of a soldering station or even a lighter. Usually this is enough to read the regular contents of the software. In such cases, the chip must be replaced with a new one.Main features of the HYUNDAI H-LED24V15 device:
The matrix (LED panel) C240X13-E3-A is installed.
The required supply voltage for all nodes of the HYUNDAI H-LED24V15 TV provides a switching power supply.
MainBoard - the main board (motherboard) is a JUC7.820.00094330 module, using Cpu chips: TSUMV59XES-XG, Flash: 25Q32 and others.
HYUNDAI H-LED24V15 TV with C240X13-E3-A LCD display, 24 "(61 cm) diagonal size of 16: 9 format. The required brightness of the screen is 230 cd / m² by LED backlighting. Contrast as the ratio of maximum brightness to minimum , is 1000: 1. In the manufacturing technology of the screen of this TV model, LED LED backlighting is implemented.

Attention! The panel C240X13-E3-A of an HYUNDAI H-LED24V15 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!
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.
