General recommendations for TV LCD LED repair
Repair of the SUPRA STV-LC32663FL TV should begin with a careful external examination of all its components and modules. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before starting the necessary measurements. In most cases, the repairman can guess about the causes of the defect and the possible consequences by the characteristic signs of typical defects in TVs, for example, the formed ring cracks in the soldering of the element terminals, swollen capacitors of the rectifier filter, charred resistors and other circuit elements.
If SUPRA STV-LC32663FL does not turn on, no indicator lamps on the front panel will light up or blink, therefore, there is a very high probability of a power module malfunction. In some cases, only the processor power supply regulator may be faulty. When repairing a power supply, it is advisable to start diagnostics with checking the mains fuse and electrolytic capacitors of the filters of the secondary rectifiers of the converter. In the event of a break in the fuse, the cause should be sought in the power semiconductor elements of the pulse converter of the main power supply unit. It is necessary first of all to check the diodes of the rectifier bridge of the mains voltage and the power switch (s) of the converter.
The reasons for the breakdown of the power switch in switching power supplies (SMPS) can be different, for example, a malfunction of semiconductor elements or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of a PWM controller microcircuit or breaks in resistors in its strapping.
Sometimes the SUPRA STV-LC32663FL TV does not have a picture, but there is sound, or the picture appears and immediately disappears. In this case, there is a high probability of malfunction of the T320HVN01.V2 panel backlight LED converter, or an open circuit in the LED circuit is possible. In such cases, first of all, it is necessary to make sure that all electrolytic capacitors of the filter are in good working order for the power supply of the LED driver itself, including the power supply unit (power supply unit).
To check the health of the LEDs, as well as the contact connections in the ruler circuit, the panel must be disassembled.
When trying to detect a break in the LED lines, it should be borne in mind 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.
If the 5800-A8M480-OP10 VER00.07 motherboard is faulty, first of all it is necessary to check all linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes it is possible to check the health of the MB only by replacing it.
In cases of complex MB (SSB) repairs and with the necessary skills and equipment, it may sometimes be necessary to replace its SPI FLASH EN25Q32 chips and other possible faulty components. Malfunctions associated with the use of BGA soldering technologies are usually easily diagnosed by the warm-up method.
Before replacing the ET-9Z2E-CF106H tuner, if there is no tuning to the channels, you must first check the supply voltage at its terminals, including the power supply of the varicaps (30-33V).
Attention! Users and owners of STV-LC32663FL TVs who do not have the appropriate qualifications, knowledge and experience are strongly advised against trying to repair themselves in order to avoid negative consequences that may lead to complete non-repairability of the device.

In case of malfunctions in the SPI FLASH software manufactured by Winbond, sometimes they can temporarily restore their performance after temperature exposure, for example, warming up with a soldering station or a lighter. This is often enough to be able to read the standard software content. The microcircuit after that must be replaced with a new one.

Attention! SUPRA STV-LC32663FL LED TV panel T320HVN01.2 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.
