General repair guidelines for TV LCD LED
MYSTERY MTV-2213LW, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. In some cases, visible external damage to the elements can suggest the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of the nodes of electronic circuits. 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.
If the power supply module malfunctions, the external manifestations may be different, for example, the MYSTERY MTV-2213LW does not turn on at all and there is no indication of the indicator lights on the front panel. With the same symptoms, the stabilizer (converter) of the power supply to the control processor may be faulty. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should begin by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
If the MYSTERY MTV-2213LW does not have an image, but there is sound, the backlight LEDs of the M215HGE-L10 // CLAA215FA10 panel or their power converter may malfunction. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
To check the health of the LEDs, as well as contact connections in the ruler circuit, it is necessary to disassemble the panel.
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.
If the motherboard MSTV2402-ZC01-01 // MSTV2407-ZC01-01 is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - Cpu: MST6E181VS-LF-Z1, Spi Flash: MX25L3206E, Eeprom: 24C16 with new or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
The malfunction of the F33WT-3DDR-E tuner is established after checking the software and all the supply voltages at its outputs, including the varicap supply voltage (30-33V).
We recommend the owners of the MTV-2213LW TV for repair only to qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

The appearance of the MainBoard MSTV2407-ZC01-01 is shown in the figure below:MSTV2407-ZC01-01
MSTV2407-ZC01-01 motherboard is combined with a power module. The processor is MST6E182VG, or MST6E181VG, made using BGA technology. Repair of the power module is carried out according to conventional technology, starting with checking its power elements. The following is a functional check of the converters for the processor power: + 1.3V, + 1.8V, 3.3V, based on SY8008B PWM controllers. The power supply of the built-in DDR 2.5V is generated from a 3.3V source using the P-N junction of the 1N4001 diode (3.3V-0.8V = 2.5V). Standby mode is organized from the linear stabilizer series 1117-3V3. The LCD panel is powered by either 5V or 12V, depending on the type of panel used.
MSTV2402-ZC01-01 can be used in TVs:
MYSTERY MTV-2214LW (Panel CLAA215FA10), MYSTERY MTV-2213LW (Panel M215HGE-L10), MYSTERY MTV-2221LD (Panel M215HGE-L10 REV.C1).
Main features of the MYSTERY MTV-2213LW device:
Installed matrix (LED-panel) M215HGE-L10 or CLAA215FA10.
