ERISSON 32LEN60
General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular ERISSON 32LEN60, it is advisable to start with a careful external examination of internal and external elements. Many visible changes in the state of the elements make it possible to determine the future direction of the troubleshooting. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
In the absence of any signs of operability, when the ERISSON 32LEN60 does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the TV power module. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. When diagnosing and repairing the power supply, first of all, replace the swollen capacitors of the filter of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip can also cause a breakdown of the power switch of the converter.
If the ERISSON 32LEN60 TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the LTA320AP24 panel is likely. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for an overstated ESR.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source.
Diagnostics and repair of the motherboard T.MS18VG.81B 11467 is carried out by checking the performance of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Board repair and replacement of CPU chips: MST6M182VG-LF-Z1; SPI Flash: 25Q32BSIG; SOUND: TPA3110D2; are made in the presence of the necessary equipment, and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
The malfunction of the tuner CDT-3SP5I2-36 is established after checking the software and all the supply voltages at its terminals.
Attention! For users and owners of 32LEN60 TVs who do not have the appropriate qualifications, knowledge and experience, we strongly recommend against attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

The appearance of MainBoard T.MS6M181.6A is shown in the figure below:
Repairing the motherboard T.MS6M181.6A, which uses the multi-function processor MST6M181VS, combined with a scaler, it is advisable to start by checking the power supply of the standby mode (Stand-by), which is implemented using a separate linear stabilizer 3.3V. Further, in the operating mode, it is necessary to check the operability of linear stabilizers or voltage converters necessary to provide power to the processor nodes: 1.2V, 2.5V, 3.3V. A voltage of 2.5V is required to power the DDR W9425G6JH memory. If there is a backlight and no image, the power of the LCD panel 5V or 12V, depending on the type of panel used, it is advisable to measure directly on the LVDS connector. If the TV does not exit Stand-by, does not respond to the remote control and control buttons, update the SPI FLASH software.
T.MS6M181.6A can be used in TVs:
AKAI LTA-32L09P (Panel LTA320AP05), ERISSON 32LEN60 (Panel LTA320AN01 D02 ), ERISSON 32LEE01 (Panel 720p HD 1366x768), HAIER LE32Z50 (Panel T315XW06 V5), Hyundai H-LED32V6 (Panel HV320WXC-100), HYUNDAI H-LEDVD32V6 (Panel V320BJ2-P01), HYUNDAI H-LED32V16 (Panel CX315LEDM).
