SHARP LC-60LE635RU
General repair guidelines for TV LCD LED
Repair of the TV SHARP LC-60LE635RU should begin with the diagnosis of a malfunction, which involves a careful examination of the external and internal elements of the device. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a significant clue in the assumptions about the causes and consequences of the malfunction.
In the case when the LC-60LE635RU does not turn on, does not respond to the remote control and the front panel buttons, does not blink bulbs and does not show any signs of operability, the power module RUNTKA847WJN1 DELTA D165HP2R0C0 is probably faulty in this case. If it is serviceable with such manifestations, it is necessary to check the stabilizer (converter) of the processor power supply on the motherboard. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is broken in the power supply, in most cases a breakdown of the power key (s) 2SK3562 (Q), TK15A60U (STA4, Q), BT169B, 126 thyristor, which can be integrated with a PWM controller, or a separate field transistor. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the binding of the PWM regulator chip NCP1608BDR2G (8), DDA014 (18) are subject to verification. TNY264PN (8), ST9S101-T6G (6), DC-DC DDA011ADR2G, which is desirable to check with a replacement.
If there is no image when you turn on the SHARP LC-60LE635RU, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the LK600D3GW7CH R1LK600D3GW7CH panel, 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.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
When trying to identify a break in the LED lines, it should be borne in mind that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
In cases of attempts to repair the DUNTKF733WE motherboard, it is necessary to check the operability of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - IXD241WJQZ, DC-DC SN910037, MP2301E, TPS53114, SN910038 (14), MP2303A (8) and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
Once again, remind users! Attempts to self-repair a TV SHARP LC-60LE635RU without the appropriate qualifications and experience can lead to its complete failure to repair!

QPWBXF733WJN2 can be used in TVs:
SHARP LC-60LE635RU (Panel LK600D3GW7CH), SHARP LC-60LE636E-RU (Panel LK600D3GW4BH).
PSU Advanced
According to the conditions of compliance with modern world standards for household switching power supplies, the RUNTKA847WJN1 module provides for the use of a Power Factor Correction unit. The PFC circuit is a flyback converter based on the NCP1608BDR2G PWM controller. The reactance of an electrolytic capacitor of a line filter at a frequency of 50-60 Hz is usually not more than 20-30 ohms and its charge directly from the network through open diodes could reach tens of amperes per pulse if no filtering were applied.
As a result of the PFC conversion, an increased voltage on the capacitor (about 380V) cannot directly open the rectifier diodes, on the anode of which the voltage will always be slightly less (about 300V) and then its charging current will always be limited by the elements of the PWM controller. As a result, the envelope of the high-frequency pulses of the consumed current will repeat the shape and phase of the input sinusoidal voltage. The presence of an increased voltage (+ 380V) on the network capacitor indicates the serviceability of the PFC node.

Attention! The LK600D3GW7CH panel of the SHARP LC-60LE635 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.
