General repair guidelines for TV LCD LED
Possible malfunctions
- The TCL 39D3320 TV does not turn on and does not show any signs of operability at all. There is no reaction to the remote control and control buttons from the front panel.
With similar manifestations, in some cases, the 40-E371C4-PWG1XG power module is faulty. It is necessary to measure its output voltages, and in case of their absence (full or partial), it is necessary to check the serviceability of the power switches of the converters and rectifier diodes for the presence of a possible 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.
Mos-Fet power switches, used in switching power supplies, sometimes fail due to a malfunction of any other elements that can put it out of operation in key mode, or create an excess of the maximum permissible parameters of the switch. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. FAN7930C, FSFR1700XS, VIPER17L PWM controllers, in the absence of visible damage or frank short-circuit between the terminals, are checked by replacing with new, or obviously working.
- There is no image, there is sound, it responds to the remote control. Or the image may appear for a second when turned on and immediately disappears.
In most of these cases, a malfunction is detected in the nodes and backlight elements of the LED panel. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
When trying to detect a break in the LED lines, it should be taken into account 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.
- 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). Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing CPU elements: MST6E182VS-LF, EEPROM: 24C64, SPI Flash: EN25Q32B-104HIP, DDR2 SDRAM 800MHz 84-FBGA - K4T51163QJ-BCF7 requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can sometimes be diagnosed by warming up.
If you suspect a malfunction of the F35WT-3-E tuner, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary levels of supply voltage and impulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.
Attention! For users and owners of 39D3320 TVs who do not have the appropriate qualifications, knowledge and experience, we strongly recommend against self-repair attempts to avoid negative consequences that could lead to complete non-repairability of the device.

The appearance of the power supply
Main features of the TCL 39D3320 device:
Installed matrix (LED-panel) LVF390CMTM E13 V2.
The matrix control uses the Timing Controller (T-CON) V390HJ1-XCO1.
The LED driver 40-RL4010-DRG1XG is used to power the backlight LEDs.
The necessary supply voltages for all nodes of the TCL 39D3320 TV are generated by the 40-E371C4-PWG1XG power supply module or its analogs using FAN7930C, FSFR1700XS, VIPER17L microcircuits.
MainBoard - the main board (motherboard) is a 40-MS82S0-MAD2XG module using CPU chips: MST6E182VS-LF, EEPROM: 24C64, SPI Flash: EN25Q32B-104HIP, DDR2 SDRAM 800MHz 84-FBGA - K4T51163QJ-BCF7 and others.
The F35WT-3-E tuner provides television reception and channel tuning.
The TCL 39D3320 TV with an LVF390CMTM LCD, 39 "(99 cm) diagonal size is 16: 9. The LCD panel of this TV has an end-face LED backlight - Edge LED. The design and technical capabilities of the TV include watching programs and movies in high HD quality at a resolution of 1920x1080 pixels in a graphic decomposition according to the standard 1080p (Full HD). The input high-frequency or video signal can be processed in analogue systems PAL, SECAM, NTSC. Graphic processing and digital signal generation takes place in the standards 480i, 576i, 576p, 720p, 1080i Supported multimedia file formats: MP3, WMA, MPEG4, Xvid, MKV, JPEG. Stereo sound is realized by two built-in speakers. NICAM STEREO audio processing system is used.

To connect a computer or laptop to this TV model, a VGA (D-Sub 15) connector is used on the TV case, this interface supports resolutions: 640x480, 800x600, 1024x768, 1280x1024, 1360x768.
Attention! The panel of the LVF390CMTM E13 V2 of the TCL 39D3320 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.
