General recommendations for TV LCD LED repair
Possible malfunctions
- SUPRA STV-LC47S660FL00 does not turn on and does not show any signs of operability at all. Does not blink indicators and does not respond to control buttons.
With similar manifestations, in some cases, the power module 5800-P47ELL-W010 is faulty. It is necessary to measure its secondary output voltages, and if they are absent, check the power switches (18N50, 2SK3673) and rectifier diodes in the converters for a short circuit.
In case of diode breakdowns in the secondary circuits, the converter can operate in an emergency mode of short circuit without output voltages, and in case of a short circuit in the power elements of the primary circuit, the mains fuse and / or the current sensor in the source of the key usually breaks off.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can disable it in the key mode, or provoke an excess of the maximum current or voltage values. These can be circuits supplying the PWM controller, damper or frequency setting circuits, or OOS (negative feedback) elements in the stabilization circuit. PWM controllers (PWM) TEA1755T, in the absence of external damage and a short circuit between the terminals, are checked by replacing them with known good ones.
- There is no image, there is sound, it reacts to the remote control. Or, immediately after switching on for a second, the image may appear and immediately disappear.
Usually, in such cases, a malfunction is detected in the nodes of the LED panel backlight. The reason may be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
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.
- TV does not turn on, does not respond to the remote control. The indicator blinks or signals the standby mode.
Repair or diagnostics of the 5800-A5M91T-0P10 motherboard should begin with checking the stabilizers and power converters necessary to power the microcircuits and matrix. If necessary, you should update or replace the software (software). Repair of the board and replacement of CPU: MSD6369IV, SPI Flash: 25Q16 microcircuits are performed with the necessary equipment and the corresponding element base. Malfunctions associated with the use of BGA soldering technologies can be localized by warming up.
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.
Owners of the STV-LC47S660FL00 TV are advised to contact only qualified specialists with the necessary experience for repair! Attempts to repair yourself without the appropriate knowledge and skills can lead to irreversible negative consequences!

Main features of SUPRA STV-LC47S660FL00 device:
Installed matrix (LED panel) LC470EUJ-SFK2 1920x1080.
Matrix control uses the LC470DUE-SFD1 Timing Controller (T-CON).
The LED driver 168P-P47DWM-W2 is used to power the backlight LEDs.
The formation of the necessary supply voltages for all nodes of the SUPRA STV-LC47S660FL00 TV is carried out by the 5800-P47ELL-W010 power module, or its analogs using TEA1755T microcircuits and power switches of 18N50, 2SK3673 type.
MainBoard - the main board (motherboard) is a 5800-A5M91T-0P10 module, using CPU chips: MSD6369IV, SPI Flash: 25Q16, Nand: TNGBM4G4D1HBAIR and others.
Tuner NoName provides reception of television programs and tuning to channels.

Attention! The panel LC470EUJ-SFK2 1920x1080 LED TV SUPRA STV-LC47S660FL00 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 unrepairable.
