SHARP LC-32SH130E
General recommendations for repairing TV LCD
Any repair usually begins with an external inspection. Many visible changes in the state of the elements make it possible to determine the future direction of the troubleshooting. 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.
Faults in the 17PW82-2 power module can be expressed in different ways, for example, the SHARP LC-32SH130E does not turn on at all and the control lamps on its front panel do not light up and do not blink, and there are no signs of operability. After checking the mains fuse and power elements of the primary power supply circuit, it should also check the absence of a short circuit in the loads of the secondary rectifiers.
If the power keys of the pulse converter are not equal, you should pay attention to other elements in their bundling, which may be the result or cause of their breakdown.
If the SHARP LC-32SH130E 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. It is necessary to take into account that in cases of inverter protection shutdown (in order to be able to diagnose) there is a risk of failure of the inverter power elements and take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
On the 17MB60-4 motherboard, in case of a malfunction, you should first check the performance of all the stabilizers and power converters of the microcircuits, and also, if necessary, update the software (software). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the CPU elements: MSD9WB9PX-LF-2; SPI Flash: MX25L8006E; K9F1208UOC, W971GG6JB-18. BGA chip malfunctions are usually easy to detect by warming up.
If you suspect a malfunction of the DT0S403LH122E tuner, first of all, you need to verify the correctness of the software, as well as the presence of the necessary voltage levels at the corresponding terminals of the tuner.
It should be remembered! Attempts to repair the TV SHARP LC-32SH130E, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability 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 LCD panel 5V or 12V, 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.

The appearance of the power supply
Main features of the SHARP LC-32SH130E device:
Installed matrix (LCD-panel) LC320WXN / 720p HD.
The matrix control uses the Timing Controller (T-CON) LC320WXE-SCA1.
The formation of the necessary supply voltages for all nodes of the SHARP LC-32SH130E TV is carried out by the 17PW82-2 power supply module, or its analogs.

Attention! The LCD TV panel SHARP LC-32SH130 is its most expensive component.
Avoid hitting the glass and exerting pressure on the screen to avoid permanent damage to the LCD panel!
If SHARP LC-32SH130 hangs during operation, does not respond to either the remote control or the buttons on the control panel, rebooting sometimes helps. To do this, you must completely disconnect the TV from the network by pulling the plug from the outlet, and turn it back on after 10-15 seconds.
In some cases, before calling the repair service, you should make sure that your TV is really defective.
If the SHARP LC-32SH130 does not turn on or periodically turns off, it is useful to check the sockets and extension cords at the points where the TV is connected to the network, for example, using a regular table lamp.
If the SHARP LC-32SH130 does not respond to the remote, but the control buttons on the panel work, there is a certain probability of a malfunction of the remote (the remote does not work). It is advisable to check or replace the batteries in it.
If, when watching broadcasting programs, a notification of the absence of a signal appears (no signal), you should make sure that the TV is in the TV reception mode (digital / analog), or check the antenna or cable equipment.
You can check the operation of the TV from other external devices.
If there is no sound only when watching analog television programs, you should check the sound system in the settings. For Russia, D / K (6.5 MHz), for European countries B / G (5.5 MHz). In modern TVs, to set the color and sound standards, the region is usually selected - for Russia, “East Europe” (Eastern Europe).
