General recommendations for repairing TV LCD
HYUNDAI fault diagnosis and repair with B.TD701B-1 chassis, as well as other electronic devices, is recommended to start with an external examination of the external and internal elements. In some cases, visible external damage to the elements can suggest the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of the nodes of electronic circuits. In most cases, the repairman can guess the causes of the defect and possible consequences by the characteristic signs of typical TV defects, for example, ring cracks formed in the soldering of element leads, swollen rectifier filter capacitors, charred resistors and other circuit elements.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain probability that the power module is defective and needs repair. Sometimes with similar manifestations a problem may occur only in the absence of processor power, which is typical for certain HYUNDAI models. When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and the electrolytic capacitors of the filters of the converter secondary rectifiers. In the event of a fuse breaking, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch (s) of the converter.
The reasons for the breakdown of the power switch in switching power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or broken resistors in its bundle.
If the HYUNDAI H-LCD2202 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 B.TD701B-1 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. In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - PCU: TDA15021H / N1C00, Scaler: NT68565FC, Submicom: NT68F631ALG NVM: 24c16 Audio: TDA1517. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
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.
FIRMWARE FOR SPI FLASH -----------> HYUNDAI H-LCD2202, Main: B.TD701B-1
The appearance of the MainBoard B.TD701B-1 is shown in the figure below:MainBoard B.TD701B-1 includes a TDA15021H processor, NT68565FC scaler, Submicom: NT68F631ALG, SPI FLASH 520Kb and EEPROM 2416.
It is advisable to start the repair of the motherboard by checking all voltage converters and linear stabilizers necessary to provide power to the nodes and chips in the operating and standby modes. Check the power of the LCD panel (depending on the type, + 5V or + 12V), it is convenient to measure directly on the LVDS connector. If, in the presence of the necessary supply voltage, the TV does not exit Stand-by mode, does not respond to the Remote Control and control buttons, you should update the software (firmware) SPI Flash.
B.TD701B-1 can be used in TVs:
HYUNDAI LCDVD2200 (Panel LM220WE1), HYUNDAI H-LCD2202 (Panel HT150X02-100).
