General recommendations for repairing TV LCD
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should inspect all the internal elements of the JUG7.820.699-4 chassis, as well as the external chassis. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. 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.
Malfunctions of the power module can be expressed in different ways, for example, the HYUNDAI H-LCD2218 does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) 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 borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits 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.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but there is sound and other functions work, there is a high probability of a malfunction of the inverter (power converter for the backlight). In such cases, the lamps, the inverter and the common power module are subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the inverter should be checked. If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
The JUG7.820.699-4 LS07 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. If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - Cpu: TSUMV26KE-LF; Spi Flash: M25P40, Eeprom: 24LC32B. Defective components should be replaced.
Attention to users! Self-repair of the HYUNDAI H-LCD2218 TV without the appropriate qualifications and experience can lead to its complete non-repairability!
