General repair guidelines for TV LCD LED
Possible malfunctions
- The SHARP LC-40LE510 TV does not turn on and does not show any signs of operability at all. There is no reaction to the remote control and control buttons from the front panel.
Usually with such manifestations, the defect is caused by faulty elements in the main power module 17PW07-2. It is necessary to measure its output supply voltages, and in case of their absence, check the serviceability of power switches (FQPFN50C, A04842) of converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
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 circuits (OOS) of stabilization. PWM controllers (PWM) FAN7529 (PFC), FSDL321 (Standby), FAN7621, NCP1579, if they do not have visible damage to the case and open short circuit between the terminals, are usually checked by replacement.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
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.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source. By opening the panel, each LED can be checked separately. Typically, Chinese multimeters light up a single 3-volt LED, if you connect probes in the forward direction to it. In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the 17MB60-4 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 attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - CPU: MSD9WB9PX-LF-2, SPI Flash: MX25L8006E, NAND: K9F1208UOC which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
The malfunction of the DTOS403LH122E tuner is established after checking the software and all the supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
Attention! For users and owners of LC-40LE510 TVs who do not have the appropriate qualifications, knowledge and experience, we strongly recommend against attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

The appearance of the power supply
Main features of the SHARP LC-40LE510 device:
Installed matrix (LED-panel) LTA400HM13.
The LED driver SSL400_0E2B is used to power the backlight LEDs, it is controlled by the SSL100SN PWM controller. As power elements of the LED driver, keys of the MDD3752 type are used.
The necessary supply voltages for all nodes of the SHARP LC-40LE510 television are generated by the 17PW07-2 power module or its analogs using FAN7529 (PFC), FSDL321 (Standby), FAN7621, NCP1579 microchips and power switches of the FQPFN50C, A04842 type.
MainBoard - the main board (motherboard) is a 17MB60-4 module, using CPU chips: MSD9WB9PX-LF-2, SPI Flash: MX25L8006E, NAND: K9F1208UOC and others.
The DTOS403LH122E tuner provides TV reception and channel tuning.
