General repair guidelines for TV LCD LED
HYUNDAI H-LED19V13, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. 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.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain probability that the power module is defective and needs repair. Sometimes with similar manifestations a problem may occur only in the absence of processor power, which is typical for certain HYUNDAI models. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
If the HYUNDAI H-LED19V13 does not have an image, but there is sound, there may be a malfunction of the panel backlight LEDs or their power converter. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
It should be remembered that it is not possible to determine the open circuit in the LED lines without disassembling the panels with a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
In cases of attempts to repair the motherboard T.MS6M181.7A, 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.
If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - MST6E181VS-LF-Z1, W9425G6JH-4, GD25Q32, YD1517. Defective components should be replaced.
If there is no reception of television channels, but the TV is working properly from external devices, first of all you need to check the voltage of the varicaps of the tuner AFT7 / W1, which is usually within 30-33V, as well as other supply voltages on the terminals of the tuner.
Owners and users of the HYUNDAI H-LED19V13 TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

The appearance of MainBoard T.VST59.62 is shown in the figure below:T.VST59.62
It is advisable to start the repair of the T.VST59.62 motherboard based on the TSUMV59Xxx multifunction processor by checking the operability of linear voltage stabilizers or voltage converters necessary to provide power to the processor nodes - 1.2V core power, 1.8V DDR memory and Stand-by 3.3V mode . If there is no image, but the display backlight is working properly, you should check the power supply voltage of the LCD panel 5V or 12V, depending on the type of panel used.

Attention! The CX185LEDM panel of a HYUNDAI H-LED19V13 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.
