General repair guidelines for TV LCD LED
TV SHARP LC-22LE510RU B, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Sometimes, based on visible changes in the components of the device, it is possible to draw some conclusions and determine the direction of further troubleshooting even before the necessary measurements are taken. In most cases, the repairman can guess the causes of the defect and possible consequences by the characteristic signs of typical TV defects, for example, ring cracks formed in the soldering of element leads, swollen rectifier filter capacitors, charred resistors and other circuit elements.
If the LC-22LE510RU TV does not turn on, does not emit any sounds when it is turned on, and also no indicators light up or blink on the front panel, there is a high probability of a malfunction in the power module. In some cases, only the stabilizer or power converter of the control processor may be faulty, which is typical for some SHARP models. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in such a state of breakdown.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the ICE3BR0665J PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
If there is no image when you turn on the SHARP LC-22LE510RU, or it appears for a second and disappears, but there is sound, most likely a malfunction in the circuit of the panel backlight LEDs, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
A malfunction in the backlight circuits often occurs due to an open in the power circuit of the LED lines. It is necessary to disassemble the panel and check the LEDs themselves, the soldering of their conclusions, as well as the reliability of the connections in the connectors and the soldering of the conclusions of the connectors.
It should be remembered that it is not possible to determine the open circuit in the LED lines without disassembling the panels with a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
Repair or diagnostics of the 17MB60-4.1 motherboard should begin by checking the stabilizers or power converters of its microcircuits. If necessary, you should update the software (software).
Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing elements MP2012 (6), MP1583 (8), MP1484 (8), HY5PS121621C, AX88772, TL062, MSD9WB7PX-2, CXD2820R requires the necessary training and professional skills in repairing modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
Before replacing the DTOS403LH122E tuner, if there is no tuning for the channels, you must first check the power supply voltage at its terminals, including the power supply of varicaps (30-33V).
Attention! For users and owners of LC-22LE510RU TVs who do not have the appropriate qualifications, knowledge and experience, we categorically do not recommend attempting self-repair in order to avoid negative consequences that could lead to complete non-serviceability of the device.

The appearance of the MainBoard 17MB60-4 is shown in the figure below:The 17MB60-4 motherboard is made using the MSD9WB7PX-2 processor, combined with a scaler. For its work, two microchips of external random access memory (DDR) HY5PS121621C and read-only memory (ROM) NAND512-A are used. To ensure processor power, stabilizers 1.2V, 2.5V, 3.3V are used. For DDR, the voltage is 1.8V, for the power of NAND 3.3V. It is advisable to start the repair by checking the power supply of the standby mode 3.3V. Further, in the operating mode, it is necessary to check the operability of all linear stabilizers and voltage converters. If there is a backlight and no image, the power of the 5V or 12V LCD panel, depending on the type of panel used, can be measured directly on the LVDS connector. A typical malfunction is a NAND ROM software failure. At the same time, the TV does not turn on and the indicators on the panel blink. It is updated via the USB port if the software of the SPI FLASH chip in which the bootloader is located is not damaged, or if there is a mboot.bin file on the media, which can be used as standard SPI FLASH content.
