General recommendations for repairing TV LCD
Possible malfunctions
- The HYUNDAI H-LCD2216 TV does not turn on at all. There is no reaction to the remote control and control buttons from the front panel. Indicator lights do not light or flash.
With such manifestations, a malfunction is most likely to be detected in the AYL220426 power supply module. It is necessary to measure its output supply voltages, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM) PWM SOT23-6, in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
These manifestations can be triggered by a power module, or by defects in the inverter, as well as a distortion of the currents in the lamps due to their uneven wear. If all the electrolytic capacitors of the filter according to the inverter power supply are serviceable, you should make sure that the lamps are in good working condition, then you need to check the converter keys and the secondary windings of the transformers.
Sometimes, for diagnostic purposes, inverter protection must be disabled. In such cases, special care must be taken during work, and the protection circuit should be restored immediately after the repair is completed.
- The TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights constantly or blinks.
Repair or diagnostics of the T.VST26.3B motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). In cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - TSUM26KE-LF, YD1517, 25Q80BVSIG, ISSI 464A-2 (24C64), which MP1482DN may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
If there is no reception of television channels, but the TV is working properly from external devices, first of all it is necessary to check the voltage of the tuner TDQ-ATF27WT-F and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
We recommend the owners of the H-LCD2216 TV for repair only to qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!

The appearance of the power supply
Main features of the device HYUNDAI H-LCD2216:
Installed matrix (LCD panel) M216H1-L01.
To power the backlight, a converter is used, combined with a power supply, controlled by a TL494C PWM controller. As power elements of the inverter, keys of the type ME4946 are used.
The necessary supply voltages for all nodes of the HYUNDAI H-LCD2216 TV are generated by the AYL220426 power module or its analogs using SG6858 microcircuits (PWM SOT23-6) and power switches of the FQPF8N60C type.
MainBoard - the main board (motherboard) is a T.VST26.3B module using TSUM26KE-LF, YD1517, 25Q80BVSIG, ISSI 464A-2 (24C64), MP1482DN, and others microcircuits.
The TDQ-ATF27WT-F tuner provides TV reception and channel tuning.
