General recommendations for repairing TV LCD
It is advisable to start diagnosing a malfunction of the MYSTERY MTV-2216WD TV, like all others, with an external examination of possible changes, both external and internal elements. It often happens that some damage to elements or connections will help determine the correct direction of troubleshooting and localization of the defect. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a hint in the assumptions about the causes and consequences of the malfunction.
Sometimes the MYSTERY MTV-2216WD TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is the failure of the common power supply module MSDV1901-ZC01-02 (G) MST9E19. When diagnosing and repairing the MSDV1901-ZC01-02 (G) MST9E19 power supply unit, the fuse must first be checked, and if it is broken, the power switch and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
It should be remembered that in the practice of repair, usually the power keys of N-Fet converters do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
In cases using a power module with an active KKM, troubleshooting is sometimes somewhat more complicated.
Sometimes the MYSTERY MTV-2216WD TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the backlight converter, or of the lamps themselves, which can be checked by replacement. In such cases, it is necessary to verify the serviceability of all electrolytic capacitors of the filter according to the power supply of the inverter itself, including in the power supply unit (power supply unit).
Repairing the MSDV1901-ZC01-02 (G) MST9E19 inverter is difficult because in case of any malfunction or abnormal situation, even if the lamps are unevenly worn, a protection is triggered that turns it off for fire safety purposes. Diagnostics become impossible and protection needs to be disabled.
When diagnosing with disabled protection, special precautions must be observed, because there is a risk of failure of the power elements of the inverter. After the diagnosis, it is imperative to restore the protection circuits for the inverter to operate normally.
Repair or diagnostics of the TV motherboard: 222-090623001-090716-V216B1-P01, you must start by checking the power conditioners. If necessary, you should update the software (software). In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - MST9E19xxxx, W25X40, 24C32.
Attention to the owners! Attempts to self-repair the MYSTERY MTV-2216WD TV are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the MYSTERY MTV-2216WD device:
Installed matrix (LCD panel) V216B1-L02 Rev. C1.
To power the backlight, a converter is used, combined with a power supply, controlled by a BIT3102B PWM controller. As power elements of the inverter, keys of the type AO4828 are used.
The required supply voltages for all nodes of the MYSTERY MTV-2216WD TV are generated by the TV2201-ZC02-02 power supply module or its analogs using microchips DM07652R and power switches of the type AO4804C, AO4435.
MainBoard - the main board (motherboard) is an MSTV2203-ZC01-01 module, using CPU chips: TSUMV26KU-LF, EEPROM: 24С32, SPI: 25L4005AMI, TDA1517P and others.
The F21WT-3BAR-E tuner provides television reception and channel tuning.
