General recommendations for repairing TV LCD
It is advisable to start diagnosing a malfunction of the HYUNDAI H-LCD1502 TV, like all others, with an external examination of possible changes, both external and internal elements. Often, according to certain external signs, the repairman can draw some conclusions about the reasons for the failure of certain elements of the circuit even before the necessary measurements are made, which will determine the further algorithm for troubleshooting and localizing 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-LCD1502 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink lights and does not show any signs of operability, most likely in this case the DC 12V power supply module is faulty; 4,5A. In this case, the diagnosis and repair of the common power supply should always be started by checking the mains fuse. When it breaks, it is advisable to check for a breakdown, first of all, all power semiconductor elements of the converter and the rectifier diode bridge of the network, as well as the large electrolytic capacitor of the filter of the network rectifier and the key transistor.
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 PWM controller chip can also cause a breakdown of the power switch of the converter.
When using the Active Power Factor Correction (CMC) circuitry in the power module, the search for faulty elements is somewhat more complicated.
In those cases when the HYUNDAI H-LCD1502 TV has lost an image, and the sound is there and all the other functions are functional, there is a possibility of a malfunction of the inverter (converter for powering the backlight). When you turn on the TV, the image may appear briefly and immediately disappear. It must be borne in mind that with such manifestations, the lamps themselves also fail, the malfunction of which can be detected by replacement, by connecting to the connectors for diagnostics that are known to be serviceable and suitable in power.
When repairing the LCD REV: C 040202 inverter, it is often necessary to disable the protection for diagnostics, which, for the purpose of fire safety, turns it off in any emergency situation, for example, during a malfunction or uneven wear of the lamps, which makes it difficult to find a defect.
It should be remembered that when the protection is turned off, there is always a risk of failure of the inverter power elements during diagnosis. After repair, it is necessary to restore all standard converter protection circuits.
Diagnostics and repair of the motherboard 5800-A8T831-02 is carried out by checking the performance of power stabilizers or updating the software (software). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the elements GM5020, SM59264, VPC 3230D C5, NT7181CF, HY57V161610DTC-7, ET-TVT0310A-Q, LM2596S.
Attention to the owners! Attempts at self-repair of the HYUNDAI H-LCD1502 TV are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the device HYUNDAI H-LCD1502:Installed matrix (LCD panel) SVA150XG04TB.
An LCD inverter is used to power the backlight, controlled by a BA9741F, 9435A PWM controller. A transformer SED DA103 0409 is installed in the inverter converter. D1802 type switches are used as power elements of the inverter.
To power all internal nodes of the HYUNDAI H-LCD1502 TV, an external adapter 12V type is used; 4,5A.
MainBoard - the main board (motherboard) is a module 5800-A8T831-02, using microchips GM5020, SM59264, VPC 3230D C5, NT7181CF, HY57V161610DTC-7, ET-TVT0310A-Q, LM2596S and others.
The EWT-5F3TY-E02W tuner provides TV reception and channel tuning.
