General recommendations for repairing TV LCD
Repair of the HYUNDAI H-LCD1509 must begin with the diagnosis of the malfunction and a thorough inspection of its external and internal components, including the case ones. In some cases, visible external damage to the elements can suggest directions for troubleshooting and localizing the defect before starting the necessary measurements at the control points of the electronic circuit nodes. Electrolytic capacitors of filters with a swollen casing, as well as ring cracks formed in the soldered leads of heating elements, or a layer of coal on burnt resistors sometimes tell the repairman the causes of the malfunction and possible consequences.
In the absence of any signs of operability, when the HYUNDAI H-LCD1509 does not turn on and does not signal anything with the control lights on the panel, the adapter 12v - 4a power supply module is most likely faulty. If the mains fuse is broken in the power supply, in most cases a breakdown of the power switch 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 borne in mind that in the repair practice it is extremely rare that key transistors of the N-FET type fail for no reason that should be looked for by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, either dried electrolytic capacitors or dangling resistors of the primary circuit of the PSU, involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM controller chip are subject to verification, which it is desirable to verify by replacement.
When using the Active Power Factor Correction (CMC) circuitry in the power module, the search for faulty elements is somewhat more complicated.
If the HYUNDAI H-LCD1509 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction of the display backlight, or their power converter - inverter. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the inverter itself, including in the secondary rectifier of the main PSU.
The operation of the power circuits of the inverter and the backlight in the normal mode are controlled by special protection, which is organized for fire safety, for example, to disconnect during short circuits or breaks in high-voltage connections or when the lamps are depressurized. This protection makes it difficult to diagnose and repair the inverter.
When diagnosing with the protection off, special precautions must be taken, because there is a risk of failure of the power elements of the inverter. After diagnosis, it is imperative to restore the protection circuits for the inverter to operate normally.
Repair of the CV075GT_V3 motherboard must begin with the diagnosis and verification of all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM. Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - MST718BE-LF MSP 3415G B8 V3 TDA1517P MP1423DN AZ1084S2-3,3E1 24LC16B1 HCF4052 and replace the failed chips with new ones.
Once again, remind users! Attempts at self-repair of the HYUNDAI H-LCD1509 TV without the appropriate qualifications and experience can lead to its complete non-repairability!
