General recommendations for TV LCD LED repair
Possible malfunctions
- SUPRA STV-LC40ST1000F TV does not turn on and does not show any signs of operation at all. No response to the remote control and front panel control buttons.
In this case, the main power supply, the AC / DC voltage converter, may be faulty, the elements of which in this model are located on the main board MainBoard 5800-A7N02G-0P00. Its output voltages should be measured, and if they are absent, check the serviceability of the power switches (TO-252) of the converters and rectifier diodes for the probability of a short circuit.
In case of breakdowns in the secondary circuits of the converter, it can usually work in an emergency mode in a short circuit, and with a short circuit in the power elements of the primary circuit, the mains fuse or current sensor in the source of the key is most often cut off.
Mos-Fet power switches used in switching power supplies sometimes fail due to a malfunction of any other elements that can disable it in the key mode, or create an excess of the maximum permissible key parameters. These can be elements supplying a PWM regulator, frequency setting or damper circuits, or elements of negative feedback in the stabilization circuit. PWM controllers FA8A01, in the absence of visible damage or outright short circuits between the terminals, are checked by replacing them with new ones, or known to be working properly.
- No picture, sound, all other TV functions work. When turned on, the image may sometimes appear for a second.
As a rule, in this case, the backlight of the LED panel is faulty. Most often the reason for this is a break in the LEDs, or poor contact in the connectors of the brackets, less often the LED driver may be faulty.
To identify an open circuit in the LED lines without disassembling the panel, a current source is required. It is impossible to open the junctions connected in series with a simple multimeter; a voltage of several tens of volts is required.
- The indicator on the front panel blinks, the TV does not turn on in operating mode, does not respond to the remote control.
Repair or diagnostics of the 5800-A7N02G-0P00 motherboard should begin with checking the stabilizers and power converters required to power the microcircuits and matrix. If necessary, you should update or replace the software (software). If it is not possible to replace the MB (SSB) board, it is necessary to check the serviceability of its elements, for example, SPI Flash MX25L1606E. Defective components must be replaced.
If you suspect a malfunction of the NoName tuner, first of all, you need to make sure that the software is correct, as well as the presence of the necessary levels of supply voltages and pulses of data exchange with the processor via the I2C bus on the corresponding terminals of the tuner.
Attention to TV owners! Attempts to repair SUPRA STV-LC40ST1000F on your own are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of SUPRA STV-LC40ST1000F device:
Installed matrix (LED panel) V400HJ6-PE1 C3.
To power the backlight LEDs, a converter combined with the 5800-A7N02G-0P00 main board is used, controlled by the OZ9902DGN PWM controller.
The power module is combined with the MainBoard and is made according to the AC / DC flyback voltage converter using FA8A01 microcircuits and TO-252 power switches.
MainBoard - the main board (motherboard) is a 5800-A7N02G-0P00 module, using SPI Flash chips: MX25L1606E, and others.
Tuner NoName provides reception of television programs and tuning to channels.

Attention! SUPRA STV-LC40ST1000F LED TV panel V400HJ6-PE1 C3 is an expensive and unreliable element.
Do not allow any impacts on the glass and pressure on the screen surface to avoid damage to the LED panel!
It is also unsafe for liquid to spill onto the screen. Sometimes one drop is enough if it drips down the glass onto the cables to make the TV non-repairable.
