General repair guidelines for TV LCD LED
The IZUMI TLE32H410M TV, like many other electronic devices, it is advisable to start repairing with an inspection of all external and internal elements. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. Electrolytic capacitors of filters with a swollen body, as well as ring cracks or a layer of coal on burned-out resistors formed in the soldered terminals of the heating elements, sometimes tell the repairman the causes of the malfunction and possible consequences.
If the IZUMI TLE32H410M does not turn on, no control lights on the front panel are on or blinking, therefore, there is a very high probability of a failure of the AY072D-4SF01 power module (02, 07, 10). In some cases, only the processor power regulator may be faulty. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in such a state of breakdown.
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 the IZUMI TLE32H410M has no image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the V315B5-LE3 REV.C2 panel, or their power converter - LED driver. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
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.
The motherboard MST6M181VS-V3.0 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 cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - TAD7266 MSH9010-LF (24), M13S2561616A, PS331, 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).
In cases where there is no tuning to the local television channels, you should make sure that the varicaps supply voltage (30-33V) and other supply voltages are present at the terminals of the CTD-3BP5I2 tuner.
Remember! Attempts to self-repair by users of the IZUMI TLE32H410M TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

Main features of the IZUMI TLE32H410M device:
The matrix (LED panel) V315B5-LE3 REV.C2 is installed.
The LED driver T87D156.00 is used to power the backlight LEDs, it is controlled by the HAI 7201TC NN1030 PWM controller (16). BA2901F (14) ,. As power elements of the LED driver, keys of the AO D4126 type are used.
The necessary supply voltages for all nodes of the IZUMI TLE32H410M TV are generated by the AY072D-4SF01 power module, or its analogs .
MainBoard - the main board (motherboard) is an MST6M181VS-V3.0 module, using TAD7266 MSH9010-LF (24), M13S2561616A, PS331, and others.
The tuner CTD-3BP5I2 provides the reception of television programs and tuning to channels.
