SHARP LC-32LE40RU
General repair guidelines for TV LCD LED
Possible manifestations of defects
- The SHARP LC-32LE40RU TV does not turn on. There is no reaction to the remote control and to the control buttons from the front panel. Indicator lights do not light or flash.
In the vast majority of such cases, a malfunction is detected in the 715G5194-P01-W21-003S power supply module. It is necessary to measure the secondary output voltage, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the elements of the primary circuit, the mains fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. PWM IC_Power can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the LED strips, to open all the transitions of the LEDs, several tens of volts or more are needed, it is best to use a current source for such purposes. The breakage of several PN junctions connected in series cannot be detected with a multimeter or tester. In such cases, it is necessary to open the panel and check each LED. If your multimeter cannot open the LED transitions in forward bias, you can sometimes detect the presence of a PN junction of the protective zener diode by connecting the probes in the opposite direction. If the zener diode is broken or broken in short-circuit, then the LED is faulty and needs to be replaced.
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the 715G4504-M2A-000-005B motherboard should be started by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software).
Before replacing the tuner ENV57U09D5F, if there is no tuning to the channels, you must first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
Attention TV owners! Attempts at self-repair of SHARP LC-32LE40RU are not recommended by the manufacturer and can lead to serious negative consequences!

The appearance of the MainBoard 715G4504-M2A-000-005B is shown in the figure below:715G4504-M2A-000-005B
Main features of the SHARP LC-32LE40RU device:
Installed matrix (LED-panel) T320XVN01.0.
The matrix control uses the Timing Controller (T-CON) 32T21-C02 T320XVN01.0 ;.
To power the backlight LEDs, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the SHARP LC-32LE40RU TV are generated by the 715G5194-P01-W21-003S power module, or its analogs using IC_Power microcircuits.
MainBoard - the main board (motherboard) is a module 715G4504-M2A-000-005B, using microchips MT5366, 24C128, HY27US08561A and others.
The ENV57U09D5F tuner provides TV reception and channel tuning.

Attention! The T320XVN01.0 panel of the SHARP LC-32LE40 LED TV is an expensive and unreliable element.
Avoid any impact on the glass and pressure on the surface of the screen to avoid damage to the LED panel!
It is also unsafe to get liquid on the screen. Sometimes one drop is enough if it flows down the glass onto the cables so that the TV becomes unrepairable.
