General recommendations for repairing TV LCD
Repair of the MYSTERY MTV-2606W TV should begin with a careful external examination of all its components and modules. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. 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-2606W does not turn on at all and there is no indication of the indicator lights on the front panel. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
If the MYSTERY MTV-2606W TV does not have an image, but there is sound, the malfunction should be sure that the backlight power converter (inverter) is working properly. It is also necessary to check the electrolytic capacitors of the filter of the secondary rectifiers of the BP (power supply) for excessive ESR. Turning off the protection for diagnostic purposes, it must be remembered that in this case there is a risk of failure of the power elements of the inverter. Upon completion of the diagnosis, all regular protection circuits should be restored.
On the motherboard MSTV2605-ZC01-01 (D), in case of a malfunction, you should first check the operation of all the stabilizers and power converters of the microcircuits, and also, if necessary, update the software (software). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the CPU elements: MST6M16JS-LF; SPI Flash: 25L1605; EEPROM: 24C64WP; . BGA chip malfunctions are usually easy to detect by warming up.
Once again, remind users! Attempts to self-repair a TV MYSTERY MTV-2606W without the appropriate qualifications and experience can lead to its complete non-repairability!
FIRMWARE FOR SPI FLASH -----------> MYSTERY MTV-2606W, Main: MSTV2605-ZC01-01 (D), Panel: V260B1-L17
The appearance of the MainBoard MSTV2605-ZC01-01 is shown in the figure below:MSTV2605-ZC01-01
Main features of the MYSTERY MTV-2606W device:
Installed matrix (LCD-panel) V260B1-L17.
To power the backlight, a converter is used, combined with a power supply, controlled by the OB3328U PWM controller. As power elements of the inverter, switches of the type AP4511GH are used.
The necessary supply voltages for all nodes of the MYSTERY MTV-2606W TV are generated by the TV2601-ZC02-01 power supply module or its analogs using OB6563, OB2269CP microcircuits and power switches of the type FQPF10N50, 2SK2843.
MainBoard - the main board (motherboard) is an MSTV2605-ZC01-01 module, using CPU chips: MST6M16JS-LF; SPI Flash: 25L1605; EEPROM: 24C64WP; and others.
The F21WT-3BAR-E tuner provides television reception and channel tuning.
