General recommendations for repairing TV LCD
Repair of all electronic devices, including the HYUNDAI TV, made on the basis of the chassis 5800-A8M61A-02, it is advisable to start with an external examination of its external and internal elements. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the solders of the terminals of transformers or heating elements are found, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
Faults in the JSK4210-022 Rev: 1.4 power module can be expressed in different ways, for example, the HYUNDAI H-LCD3206 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. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
Power switches in switching power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The cause may be a malfunction of the PWM controller chip, which can only be checked by replacing it with a new or obviously working one.
If the HYUNDAI H-LCD3206 does not have an image, but there is sound and the TV is controlled from the remote control, a malfunction in the display backlight nodes is likely. The lamps or the power converter - inverter may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the inverter, and check the LCD lamps by connecting external and obviously serviceable for diagnosis to the connectors. All necessary precautions must be observed when disabling the inverter protection during diagnostics and not leaving it disconnected after the repair is completed.
If the motherboard 5800-A8M61A-02 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. When repairing an MB board, you need to check its CPU components: MST9U88L-LF, Flash: EN25F40, EEPROM: AT24C64AN. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating. If chips with BGA soldering technology are used, a problem in its implementation is detected by the local heating of the chip.
Owners and users of the HYUNDAI H-LCD3206 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!

PSU Advanced
The JSK4210-022 power module is made using the Power Factor Correction (PFC) scheme to eliminate multiple AC harmonics introduced into the power supply by the device. The PFC assembly is a Step-Up Converter based on the L6562D PWM controller, which evenly distributes high-frequency impulses of the charging current of the electrolytic capacitor of the rectifier filter of the mains voltage over a period of 50 Hz. The current of its charge in this case will already be determined not by its reactance (usually 10-30 ohms for the network frequency), but by the elements of the converter. As a result, a change in the amplitude of the pulses (envelope) of the consumed current of the converter will repeat the shape and phase of the input sinusoidal voltage. The availability of an increased voltage (about + 380V) in the operating mode on the capacitor of the line filter indicates the serviceability of the PFC node.
The appearance of the power supply
Main features of the device HYUNDAI H-LCD3206:
The matrix (LCD panel) LTA320WT-L05 is installed.
The necessary supply voltages for all nodes of the HYUNDAI H-LCD3206 television are generated by the JSK4210-022 power supply module or its analogs using microchips L6599D (PWM Resonant), L6562D (PFC), LM393 and power switches of the type KHB9D0N50F, FTA04N65.
MainBoard - the main board (motherboard) is a 5800-A8M61A-02 module, using CPU chips: MST9U88L-LF, Flash: EN25F40, EEPROM: AT24C64AN and others.
The TDQ-6F6H / T11B6CWA tuner provides television reception and channel tuning.
