General repair guidelines for TV LCD LED
Sometimes the SHARP LC-39LE651RU TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is the failure of the RDENCA459WJQZ common power supply module. If it is working properly, you must check the standby batteries on the Main Board. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chips FAN7930CMX, SSC9522S, STR-A6069H, MP1583DP from the manufacturer.
Sometimes the SHARP LC-39LE651RU TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a possibility of a malfunction of the LED driver - the power converter of the backlight LEDs of the V390HK1-LE6 Rev.C4 panel, or a break in the LED circuit is possible. In such cases, first of all, it is necessary to verify the operability of the electrolytic capacitors of the filter by supplying the backlight unit.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
It is impossible to check the line of series-connected LEDs without a special current source, and for this purpose it is not safe to use any voltage sources above 12V for them. Then it remains only to open the panel and check each LED separately. Usually, Chinese 9V-powered multimeters light up a single 3-volt LED, if you connect the probes in the forward direction, the red probe to the anode, and the black to the cathode. 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.
If the QPWBXG135WJ motherboard is faulty, first of all it is necessary to check all the linear stabilizers and power converters of its chips, as well as, if necessary, update the software (software). Sometimes you can check the health of MB only by replacement.
In cases of attempts to repair the MB board (SSB), it is necessary to check the health of its elements - FLI7560-AAB, 29F2G08ABAEA, BR24T64J, BR24T02J, MT41J128M16JT, STM8S105K4T, BU33TD3WG, BU16028KV, Si2168, LCX244, LCX245, BD80GA3WEFJ, KSZ8081RNDTR, BD9328EF, BD95841MUV, USB2514BA, S170B50U, STA333BW which may require replacement with new ones. If the 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).
We recommend the owners of the LC-39LE651RU TV for repair only to qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!
To reduce the backlight current in LED drivers with the HAI7203HA controller, the total resistance of the resistors from terminal 12 (ISET) to the housing should be increased. Currents will proportionally decrease in each of the 8 channels. With a parallel connection of channels, the currents are added up.

PSU Advanced
The RDENCA459WJQZ power supply module is made using the Power Factor Correction (PFC) scheme to eliminate multiple AC harmonics introduced into the power supply by the device. The PFC node is a Step-Up Converter based on the FAN7930CMX PWM controller, which evenly distributes high-frequency pulses of the charging current of the electrolytic capacitor of the rectifier filter of the mains voltage over a period of 50 Hz. The current of its charge in this case will already be determined not by its reactance (usually 10-30 ohms for the network frequency), but by the elements of the converter. As a result, a change in the amplitude of the pulses (envelope) of the consumed current of the converter will repeat the shape and phase of the input sinusoidal voltage. The availability of the increased voltage (about + 380V) in the operating mode on the capacitor of the line filter indicates the serviceability of the PFC node.

Attention! The V390HK1-LE6 Rev. C4 panel of the SHARP LC-39LE651 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.
