General recommendations for repairing TV LCD
Repair of the HYUNDAI TV with the JUG7.820.037-1 chassis should begin with a careful external examination of all its components and modules. Using visible changes in the state of components, it is usually possible to determine the further direction of troubleshooting and localization of the defect before the necessary measurements are taken. 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.
If the HYUNDAI H-LCD1500 does not turn on, no control lights on the front panel light up or blink; therefore, there is a very high probability of a power module malfunction. In some cases, only the processor power regulator may be faulty. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
If the HYUNDAI H-LCD1500 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. When disabling the inverter protection (to enable diagnostics), special care must be taken in view of 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.
The JUG7.820.037-1 motherboard must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up continuously. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary. In some cases, chip repair may be required to repair the MB (SSB) board - CPU SCALER: MST718BU-LF, FLASH: 25X20VNG, EEPROM: 24LC32, IF: TDA9886TS, 4-Channel Input Audio Processor: PT2314, Audio Out: YD1517P with new or obviously good. In cases where BGA technologies are used, defects are usually localized by the heating method.
Remember! Attempts to self-repair by users of the HYUNDAI H-LCD1500 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!
