General repair guidelines for TV LCD LED
Possible malfunctions
- TCL 39E5000F3D does not turn on and does not show any signs of performance at all. Does not blink indicators and does not respond to control buttons.
Most likely in this case, the main switching power supply (IIPS) PE421C5 is faulty. It is necessary to measure the output voltages in its secondary circuits, and if they are completely absent, check the serviceability of the power switches (K12A50D) and rectifier diodes for possible breakdown (short circuit).
In case of any breakdown of semiconductors in the secondary circuits, the converter can usually work normally in emergency short circuit mode. There are no output voltages. And with a short circuit in the power elements of the primary circuit, as a rule, the mains fuse breaks and less often the current sensor at the source of the key.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback circuits (OOS) of stabilization. PWM controllers (PWM) FSL206MR, FAN7930C, FSFR1700XS, if they do not have visible damage to the case and open short circuit between the terminals, are usually checked by replacement.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
Usually in such cases, a malfunction is detected in the backlight nodes of the LED panel. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the LED strips, to open all the transitions of the LEDs, several tens of volts or more are needed, it is best to use a current source for such purposes. The breakage of several PN junctions connected in series cannot be detected with a multimeter or tester. In such cases, it is necessary to open the panel and check each LED. If your multimeter cannot open the LED transitions in forward bias, sometimes you can detect the presence of a PN junction of the protective zener diode by connecting the probes in the opposite direction. If the zener diode is broken or broken in short-circuit, then the LED is faulty and needs to be replaced.
- The TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights constantly or blinks.
Repair or diagnostics of the 40-MS82S0-MAD2XG 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). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the elements MST6E182VS-LF, 25Q32A-100HIP, 24C64, K4T51163QT-BCF7, IT6633E-P, TPA3110D2. BGA chip malfunctions are usually easy to detect by warming up.
Before changing the F35WT-3-E tuner, if it is not possible to tune to television channels, make sure that there are supply voltages that must be measured at the corresponding tuner pins and checked for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
- Owners and users of the TCL 39E5000F3D TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

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, currents are summed.

Key Features of the TCL 39E5000F3D:
Installed matrix (LED-panel) V390HK1-LS5.
The matrix control uses the Timing Controller (T-CON) V236H3-CS3-C.
The LED driver L390H1-1EC is used to power the backlight LEDs, it is controlled by the ATP360A13, HAI7203HA, HAI5208BP PWM controller. As the power elements of the LED driver, keys of the type M8014D are used.
The necessary supply voltages for all nodes of the TCL 39E5000F3D TV are generated by the PE421C5 power module or its analogs using FSL206MR, FAN7930C, FSFR1700XS microchips and K12A50D type power switches.
