General recommendations for repairing TV LCD
It is advisable to start repairing the HYUNDAI H-LCD2206 Erisson 22LS01 TV with an external examination of all its components, both internal electronic components and external. Inspection is also subject to body elements, control buttons, screen, connectors and cords. Many visible signs make it possible to determine the future direction of troubleshooting and localization of the defect. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
Faults in the 5800-PL22CL-00 power supply module can be expressed in different ways, for example, the HYUNDAI H-LCD2206 Erisson 22LS01 does not turn on at all and the control lamps on its front panel do not light up and do not blink, and there are no signs of operability. If the mains fuse is broken in the power supply, in most cases a breakdown of the power switch K2645 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.
It should be remembered that the N-FET keys used in flyback converters rarely fail for no reason that must be sought by checking other elements of the circuit. 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 LD7575PS PWM controller chip (8) can also cause a breakdown of the power switch of the converter.
In cases where the Power Factor Corrector (PFC) is used in the power supply, troubleshooting can be a bit more complicated.
Sometimes the HYUNDAI H-LCD2206 Erisson 22LS01 TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the backlight converter, or of the lamps themselves, which can be checked by replacement. In such cases, it is necessary to verify the serviceability of all electrolytic capacitors of the filter according to the power supply of the inverter itself, including in the power supply unit (power supply unit).
In most cases, the diagnosis and repair of the 5800-P8M32I-02 inverter is difficult due to the organization of protection, which turns it off in emergency cases to avoid fires during short circuits or breaks in high-voltage circuits and during depressurization of lamps. Often, repairmen block the protection circuits in order to make the necessary measurements at the control points of the inverter to identify the causes of the defect.
In these cases, special care must be taken due to the risk of failure of the power elements. After completing all repair work, it is imperative to restore the protection circuits for full and safe further operation of the TV by the user.
In cases of attempts to repair the motherboard 86041M, it is necessary to check the operability of the power stabilizers of the microcircuits and, if possible, update the software (software). In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - BD3888FS, TDA9881TS, MST718BU-LF, 24C16WP, BD3888FS, P06B03.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of electronic equipment repair.

Main features of the device HYUNDAI H-LCD2206:
Installed matrix (LCD panel) LTM220M1-L01.
The matrix control uses the Timing Controller (T-CON) LTM220M1S2LV2.2.
To power the backlight, an inverter 5800-P8M32I-02 is used, it is controlled by the PWM controller SP5001Q (20). A transformer 5134-062023-00 YMX-705-097 is installed in the inverter converter. As power elements of the inverter, keys of the AO4606 type are used.
The necessary supply voltages for all nodes of the HYUNDAI H-LCD2206 television are generated by the power supply module 5800-PL22CL-00, or its analogues using LD7575PS (PWM flyback) microcircuits and K2645 type power switches.
MainBoard - the main board (motherboard) is a module 5800-A8M32A-03, using microchips MST718BU-LF, 24C16WP, BD3888FS, P06B03, TDA9881TS, EN25P20 and others.
The TDQ-6F6 / T126CWADC tuner provides television reception and channel tuning.
