General recommendations for repairing TV LCD
It is advisable to start repairing a SHARP LC-32S2RU TV, like any others, with an examination of the internal and external visible physical visual changes. Often, by the external signs and nature of some damage, it is possible to draw preliminary conclusions and determine a further algorithm for troubleshooting. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
In the absence of any signs of operability, when the SHARP LC-32S2RU does not turn on and does not signal anything with the control lights on the panel, the power module is most likely faulty. If the mains fuse is broken in the power supply, in most cases a breakdown of the power switch is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
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.
In cases where the Power Factor Corrector (PFC) is used in the power supply, troubleshooting can be a bit more complicated.
If the SHARP LC-32S2RU does not have an image, but there is sound, there is a possibility of a malfunction of the backlight or power converter. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
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.
It should be remembered that when the protection is turned off, there is always a risk of failure of the power elements of the inverter during diagnosis. After repair, it is necessary to restore all standard converter protection circuits.
Attention to the owners! Attempts to repair the TV SHARP LC-32S2RU by yourself are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the SHARP LC-32S2RU device:
Installed matrix (LCD panel) T315XW01 V.5.
The matrix control uses the Timing Controller (T-CON) T315XW01.
To power the backlight, an inverter 4H.V1448.291 is used, it is controlled by the PWM controller OZ964SN. A transformer 4004L612.313 (GP) is installed in the inverter converter.
The necessary supply voltages for all nodes of the SHARP LC-32S2RU television are generated by the power supply module CEF213A, or its analogs using microcircuits STR-W6765, STR-X6768N.
MainBoard - the main board (motherboard) is a CEF170A module, using microcircuits MST9883C, NJM2584AM, SII9011CLU, AN15853B, R8J66607A72FP, OEC7166A, MM1501XNRE, TA2024 and others.
The TAFV-W322D tuner provides television reception and channel tuning.
