General repair guidelines for TV LCD LED
Possible manifestations of defects
- AIWA 47LE71113 TV does not turn on at all. There is no reaction to the remote control and control buttons from the front panel. Indicator lights do not light or flash.
Failure in such cases should begin to be sought in the power supply circuits of 168P-P47ELL-W1. It is necessary to measure its output voltages and, in case of their absence, check the serviceability of power switches (18N50, 2SK3673) and rectifier diodes in the converters for possible breakdown.
In case of breakdowns in the secondary circuits, the converter, as a rule, can emergency work in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse usually breaks.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback (OOS) stabilization circuits. PWM controllers (PWM) TEA1752 (PFC + PWM), if they do not have visible damage to the case and open fault between the terminals, are usually checked by replacement.
- There is no image, there is sound, it is responding to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
As a rule, in such cases there is no display backlight. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
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 5800-A8M51B-0000 motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its CPU chips: MSD6329SV, Eeprom: K24C04, SPI Flash: 25L1606E (MX25L1605A), NAND Flash: TC58NVG1S3ETA00 and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
If a TDST-G070D tuner is suspected of malfunction, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary supply voltage levels and data exchange pulses with the processor via the I2C bus on the corresponding tuner pins.
Owners and users of the AIWA 47LE71113 TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

Key Features of AIWA 47LE71113:
Installed matrix (LED panel) LC470EUJ-SFK2 (SEL470FY).
The LED driver 168P-P47DWM-W2 is used to power the backlight LEDs.
The necessary supply voltages for all nodes of the TV AIWA 47LE71113 are generated by the 168P-P47ELL-W1 power supply module or its analogs using TEA1752 microcircuits (PFC + PWM) and power switches of the 18N50, 2SK3673 type.
MainBoard - the main board (motherboard) is a 5800-A8M51B-0000 module, using CPU chips: MSD6329SV, Eeprom: K24C04, SPI Flash: 25L1606E (MX25L1605A), NAND Flash: TC58NVG1S3ETA00 and others.
