General repair guidelines for TV LCD LED
Diagnostics of malfunctions and repairs of the HYUNDAI H-LED32V5, as well as other electronic devices, is recommended to begin with an external examination of the external and internal elements. Many visible changes in the state of the elements make it possible to determine the further direction of troubleshooting and localization of the defect. 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.
In the case when the H-LED32V5 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink bulbs and does not show any signs of operability, the K-75L1 power supply module is probably faulty in this case. If it is serviceable with such manifestations, it is necessary to check the power supply stabilizer (converter) of the processor on the motherboard. When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and the electrolytic capacitors of the filters of the converter secondary rectifiers. In the event of a fuse breaking, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch (s) of the converter.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
If there is no image when you turn on the HYUNDAI H-LED32V5, or it appears for a second and disappears, but there is sound, most likely a malfunction in the backlight LED circuit of the K320WL panel, or in the 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 and contact connections in their power circuit, the panel must be disassembled.
It is impossible to check the LED line for breaks without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally, a current source.
Repair or diagnostics of the MST6M182VG-T9B motherboard should begin by checking the stabilizers or power converters of its microcircuits. If necessary, you should update the software (software).
In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its Spi Flash chips: 25Q32 and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
Before replacing the KTDANW-14-09 tuner, if there is no tuning for the channels, you must first check the supply voltage at its terminals, including the power supply of varicaps (30-33V).
Remember! Attempts to self-repair by users of the HYUNDAI H-LED32V5 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

Attention! The K320WL panel of the HYUNDAI H-LED32V5 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.
