General recommendations for repairing TV LCD
Repair of the MYSTERY TV with the V3K05 chassis should begin with a careful external inspection of all its components and modules. Many visible changes in the state of the elements make it possible to determine the further direction of troubleshooting and localization of the defect. Electrolytic capacitors of filters with a swollen casing, as well as ring cracks formed in the soldered leads of heating elements, or a layer of coal on burnt resistors sometimes tell the repairman the causes of the malfunction and possible consequences.
If the MTV-2217WD TV does not turn on, does not make any sounds when turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power supply module. In some cases, only the stabilizer or power converter of the control processor may be faulty, which is typical for some MYSTERY models. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors 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.
The reasons for the breakdown of the power switch in pulsed power supplies (IIPS) can be different, for example, a malfunction of semiconductor elements or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller DM07652R or broken resistors in its bundle.
In cases where the MYSTERY MTV-2217WD TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of a malfunction of the inverter (converter for powering the backlight). When you turn on the TV, the image may appear briefly and immediately disappear. It must be borne in mind that with such manifestations, the lamps themselves also fail, the malfunction of which can be detected by replacement, by connecting to the connectors for diagnostics that are known to be serviceable and suitable in power. It is necessary to take into account that in cases of inverter protection shutdown (in order to be able to diagnose) there is a risk of failure of the inverter power elements and take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
Motherboard MSTV2203-ZC01-01 (C) P / N: 303C2203073 must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up constantly. 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 - CPU: TSUMV26KU-LF, EEPROM: 24C32, Sound: TDA1517P 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).
Attention! Users and owners of MTV-2217WD TVs who do not have the appropriate qualifications, knowledge and experience are strongly advised against self-repair attempts in order to avoid negative consequences that could lead to complete non-repairability of the device.

Main features of the MYSTERY MTV-2217WD device:
Installed matrix (LCD panel) CLAA215FA05.
The matrix control uses the Timing Controller (T-CON) CPT215FA01CS.
To power the backlight, the inverter TV2201-ZC02 (C) is used, controlled by the BIT3102B PWM controller. The transformer BCX-19252WH1311 x2 is installed in the inverter converter. As power elements of the inverter, keys of the type AO4828 are used.
The necessary supply voltages for all nodes of the MYSTERY MTV-2217WD TV are generated by the TV2201-ZC02 (C) power module, or its analogs using DM07652R microcircuits.
MainBoard - the main board (motherboard) is an MSTV2203-ZC01-01 module, using CPU chips: TSUMV26KU-LF, EEPROM: 24C32, Sound: TDA1517P and others.
The F21WT-3BAR-E tuner provides television reception and channel tuning.
