General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular ERISSON 32LES66, it is advisable to start with a careful external examination of internal and external elements. Based on visible external changes in the state of the components, it is often possible to determine the direction of the troubleshooting before making the necessary measurements. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
If the ERISSON 32LES66 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 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 missing initially when you turn on, but the sound has other functions that work, there is a high probability of a malfunction of the LED driver (power converter for the backlight LEDs of the REL320AH-U100 Rev.00 panel).
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
A break in the line of LEDs connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
If the motherboard 5800-A8M480-0P10 is faulty, first of all it is necessary to check all the linear stabilizers and power converters of its chips, as well as, if necessary, update the software (software). Sometimes you can check the health of MB only by replacement.
In cases of attempts to repair the MB board (SSB), it is necessary to check the health of its elements - SPI Flash: EON 25Q32B; which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
If there is no reception of television channels, but the TV is working properly from external devices, first of all it is necessary to check the power supply to the tuner ET-9Z2E-CF106H and update the software.
Attention to the owners! Attempts to repair the TV ERISSON 32LES66 on its own are not recommended by the manufacturer and can lead to serious negative consequences!
