General repair guidelines for TV LCD LED
Repair of electronic devices, including the SUPRA STV-LC19663WL TV, is advisable to start with an external examination of its external and internal elements. According to some external signs of a change in the state of some elements, it is sometimes possible to make assumptions about the nature of the defect, as well as determine the further direction of the troubleshooting. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in soldering will help the master to guess the causes and possible consequences of the malfunction.
If SUPRA STV-LC19663WL does not turn on, none of the control lamps on the front panel will light up or blink, therefore, there is a very high probability of failure of the 5800-P19EWR-W100 power supply module. In some cases, only the processor power supply regulator may be faulty. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defect of the PWM chip from the manufacturer.
If SUPRA STV-LC19663WL has no picture, but there is sound and the TV is controlled from the remote control, there is likely a malfunction in the backlight circuits of the E185SG02 panel. The LEDs or the power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the LED driver, and check the LEDs, connecting obviously known good diagnostics.
In most cases of lack of backlight, there is a need to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
An open in the LED lines connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
Repair or diagnostics of the 5800-A8M470-0P40 motherboard should begin by checking the stabilizers or power converters of its microcircuits. If necessary, update the software (software).
Complex repair of MB (SSB) board is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the Flash 25Q32BSIG elements. BGA chip malfunctions are usually easy to detect by warming up.
It should be remembered! Attempts to repair the SUPRA STV-LC19663WL TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

Attention! The panel E185SG02 of the SUPRA STV-LC19663WL 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.
