General recommendations for LCD LED TV repair
Possible trouble spots
- SAMSUNG UE40JU6610U does not turn on and does not give any signs of performance. It doesn't blink and doesn't respond to the control buttons.
In some of such cases the main switching power supply - the BN44-00806A module - becomes defective. Then its output voltages should be measured and if they are not, the power switches (K8A50D) and the rectifier diodes of converters should be checked for possible short circuits.
If the semiconductors in the secondary circuits breakdown, the inverter can usually be short-circuited, and the mains fuse is often blown when the power elements in the primary circuit are shorted.
Mos-Fet power switches used in switching power supplies sometimes fail due to the failure of some other element that can take it out of key mode, or create the maximum allowable parameters of the switch. These can be elements that feed the PWM controller, the frequency-retaining or damping circuits, or negative feedback elements in the stabilization circuit. PWM controllers FA6A20N, SPC7011F, if there is no visible damage or obvious short circuit between the pins are checked by replacing with the new ones or known good ones.
If the SAMSUNG UE40JU6610U has no picture, but there is sound, often the display backlight simply does not work. Moreover, in LED TVs usually fail LEDs inside the panel, less often the LED-driver.
In such cases, you can see a barely noticeable image when external lighting hits the screen.
To replace the LEDs requires disassembly of the LCD-panel - a process that requires a master of experience and expertise. Do not perform such work by yourself to owners of TV sets and masters who have no experience in LCD panel repair
If there is no image, but backlighting is working, the screen becomes a little lighter when the TV is turned on, and in the open TV you can see the light through the holes in the body of the panel.
In this case the panel may be defective - damage to the strips, cables, for example, as a consequence of moisture after an unsuccessful washing of the screen, the T-CON board (Timing Controller) may be defective. But quite often the MainBoard is defective as well, and software failure is also possible.
Then first it is necessary to check the panel power supply voltage, fuses on the T-CON board, as well as the supply and reference voltages of the column and line drivers - VGH, VGL, Vcom.
If these measurements are within normal limits, it is necessary to trace by oscilloscope the LVDS signals from MainBoard, as well as synchronizing signals to the driver stubs.
Filled or unsuccessfully washed LED TV screens can be restored in about half of the cases, usually, if there is no significant damage in the cables and panel bars.
- No image, the screen is black, there is sound, in the external screen light you can sometimes see faintly visible outlines of the image.
Usually in such cases malfunction is detected in the nodes of LED panel backlight. Usually the cause of the malfunction is in the breakage of the LEDs or in the connectors of the LED panels V5DU-400DCA-R1, V5DU-400DCB-R1, but sometimes the LED-driver is also faulty.
To check the LED strips for breakage without disassembling the panel will help, for example, a current source. It is not possible to open the series-connected PN-junctions with a simple multimeter, you will need a voltage of about several tens of volts.
READ HOW TO REPAIR THE TV LED BACKLIGHT --------------> HERE.
- The TV does not turn on, the LED indicates standby or working mode, or blinks.
Repair or diagnosis of the motherboard BN41-02344D should begin with checking the stabilizers and power converters needed to power the chips and matrix. If necessary, software (software) should be updated or replaced. In some cases to repair the MB board (SSB) you may need to replace the chips - CPU: SDP1406, Spi Flash: 25Q40CLSIP, SOUND: NTP7415, DDR: K4B2G1646Q-BCMA with new or known good ones. In cases of BGA technology, defects are usually located by heating.
Before replacing the BN40-00318B tuner, if you cannot tune to the TV channels, make sure that the supply voltages are available and measure them at the respective pins of the tuner and check the software for correctness. The tuner-to-processor communication pulses can be checked with an oscilloscope
Warning to the users! Unauthorized repair of SAMSUNG UE40JU6610U TV without the appropriate qualification and experience can lead to its complete unrepairability (IDIOTS ARE ADVISED !

MainBoard Appearance
The main features of the SAMSUNG UE40JU6610U:
A matrix (LED panel) CY-WJ040HGLV2V is installed.
The matrix is controlled by the Timing Controller (T-CON) BN41-02297A.
The converter combined with the power supply is used to power the LED backlight and is controlled by the PWM controller SM1251. N-FET TO-220F type switches are used as power elements of LED-driver.
The power supply module BN44-00806A or its analogues with the use of FA6A20N, SPC7011F chips and K8A50D type power keys provide the formation of the required supply voltages for all the SAMSUNG UE40JU6610U TV assemblies.
MainBoard - the main board (motherboard) is a module BN41-02344D, using CPU: SDP1406, Spi Flash: 25Q40CLSIP, SOUND: NTP7415, DDR: K4B2G1646Q-BCMA and others.
The BN40-00318B tuner provides TV program reception and channel tuning.
