General repair guidelines for TV LCD LED
Possible malfunctions
- The HAIER LE43K6000SF does not turn on at all. The control lights do not light or flash. The TV on the remote control and the control panel buttons do not respond.
In such cases, the AC / DC voltage converter is often faulty, which is combined with the main board MS36633-ZC01-01. It is necessary to verify the presence of its output voltages and, if they are completely absent, check the power switches (TO-252) and rectifier diodes for a probable short circuit.
In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in emergency short-circuit mode without output voltages, and during short circuit in the elements of the primary circuit, the main fuse and, less often, the current sensor at the source of the key are most often cut off.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM SOT23-6 PWM chips are usually checked by replacing with new ones, or obviously working.
- There is no image, there is sound, all other functions of the TV work. When turned on, the image may sometimes appear for a second.
The most likely in these cases is a malfunction of the LED backlight. The reason can be found in the malfunction of the LEDs, in the violation of the contact connections of the LED strips, or in the provision of their power (LED-driver).
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can check each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN junction indirectly indicates a LED-a
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the MS36633-ZC01-01 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). 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 - SPI Flash: 25Q64 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.
The failure of the NoName 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.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Entrust repair to professionals with sufficient experience in the field of repair of electronic equipment.

The appearance of the MainBoard MS36633-ZC01-01 is shown in the figure below:MS36633-ZC01-01
Key Features of HAIER LE43K6000SF:
Installed matrix (LED-panel) LC430DUY-SHA1.
To power the backlight LEDs, a converter is used, combined with the main board MS36633-ZC01-01, controlled by an 8 pin PWM controller. As power elements of the LED driver, keys of the TO-252 type are used.
The power module is combined with the MainBoard and is made according to the flyback AC / DC voltage converter circuit using PWM SOT23-6 microcircuits and TO-252 type power switches.
MainBoard - the main board (motherboard) is an MS36633-ZC01-01 module, using SPI Flash chips: GD25Q64 and others.
The NoName tuner provides television reception and channel tuning.
HAIER LE43K6000SF TV with LCD display LC430DUY-SHA1, diagonal size 42.5 "(108 cm) in 16: 9 format. The required brightness of the screen is 250 cd / m² LED backlight LED. Contrast, as the ratio of maximum brightness to minimum, is 1200: 1. Direct LED backlighting with Direct LEDs is realized in the LCD panel of the TV. odderzhivaemye multimedia file formats: MP3, MPEG4, DivX, MKV, JPEG.
The power of the sound system 16 W (2x8 W) provide two speakers. It uses a NICAM stereo signal processing system and Sound Surround.
The external interface (communication with other devices) is supported by standard input and output connectors: antenna input (RF), AV, component, VGA, HDMI x2, USB. An output for connecting headphones is provided.
The digital tuner is capable of receiving television channels in the standards DVB-T MPEG4, DVB-C, DVB-T2, DVB-S2.
Overall dimensions: with stand 966x620x250 mm, without stand 966x559x64 mm.
TV Weight: with stand: 7.69 kg, without stand: 7.55 kg.
Attention! The panel of the LC430DUY-SHA1 HAIER LE43K6000SF 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.
