General recommendations for repairing TV LCD
Repair of the SHIVAKI STV-32L6 TV is advisable to start with an external examination of all its constituent elements, both internal electronic components and external. Inspection is also subject to body elements, control buttons, screen, connectors and cords. It often happens that some damage to elements or connections will help determine the correct direction of troubleshooting and localization of the defect. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
In the case when the STV-32L6 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink lights and does not show any signs of operability, most likely in this case the power supply module is faulty. It is advisable to start the troubleshooting of the power supply module by checking the mains fuse. If it is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and the power switch of the converter, which are often found in breakdown conditions in such situations.
In most cases, a breakdown of the N-Fet converter key does 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 an active Power Factor Corrector (PFC) is used in the power module circuitry, it is sometimes more difficult to troubleshoot. Knowledge, experience, intuition and skills in such cases have a great advantage for a successful repair.
If the SHIVAKI STV-32L6 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction of the display backlight, or their power converter - inverter. 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 inverter itself, including in the secondary rectifier of the main PSU.
Repairing the inverter is difficult because in case of any malfunction or emergency, even with uneven wear of the lamps, a protection is triggered, which turns it off for fire safety. Diagnostics become impossible and protection needs to be disabled.
All necessary precautions must be observed when disabling the inverter protection during diagnostics and not leaving it disconnected after the repair is completed.
In cases of attempts to repair the motherboard L2M015 (02) 2009.09.06, it is necessary to check the operability of the power supply circuits of the microcircuits and, if possible, update the software (software). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - MSD106CHL-LF-Z1, 25L3205DM2C, T315HW02 V.7, IJ99F (6), TMDS251, tuner DTI1-E4I2RH 9916FI and replace the failed chips with new ones.
Once again, remind users! Attempts to independently repair the SHIVAKI STV-32L6 TV without the appropriate qualifications and experience can lead to its complete non-repairability!
Main features of the SHIVAKI STV-32L6 device:Installed matrix (LCD panel) T315HW02 V.7.
The matrix control uses the Timing Controller (T-CON) T-CON: T370HW02.
To power the backlight, an inverter DS-1931T03013 is used, it is controlled by the PWM controller OZ9937GN. A transformer LKL-103 is installed in the inverter converter.
The formation of the necessary supply voltages for all nodes of the SHIVAKI STV-32L6 TV is carried out by the BL-PI400103A power module, or its analogues.
MainBoard - the main board (motherboard) is an L2M015 module, using microchips MSD106CHL-LF-Z1, 25L3205DM2C, KH25L3206E, TMDS251 and others.
The DTI1-E4I2RH 9916FI tuner provides TV reception and channel tuning.
