General recommendations for TV LCD LED repair
It is advisable to start repairing a SUPRA STV-LC32660FL TV with a careful external examination of both internal and external elements. 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. Swollen electrolytic or sintered capacitors, charred resistors, ring cracks in the soldering of the element terminals - all this can significantly help the master to determine the causes and consequences of the malfunctions in the TV.
If the TV does not turn on, none of the indicators on its front panel are on or blinking. Also, if the TV does not respond to the remote control and buttons, does not emit any sounds or any signs of operability when turned on, there is a certain probability that the power module is faulty and needs repair. Sometimes a problem with similar manifestations can occur only in the absence of processor power, which is typical for certain SUPRA models. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. If it breaks, the power elements of the transistors and diodes of the rectifier bridge should be checked for avalanche (thermal) breakdown.
In most cases, breakdowns of keys in switching power supplies (SMPS) do not occur without 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 broken resistors or punctured semiconductor elements in the stabilization circuits. Possible defect of the PWM chip from the manufacturer.
Sometimes the SUPRA STV-LC32660FL 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 a malfunction of the T320HVN01 ...? 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).
A malfunction in the backlight circuits often occurs due to an open circuit in the power supply circuit of the LED lines. It is required to disassemble the panel and check the LEDs themselves, the ration of their outputs, as well as the reliability of the connections in the connectors and the ration of the connector pins.
It is impossible to check the LED bars for a break without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally a current source.
Repair of the 5800-A8M480-OP20 motherboard must begin with diagnosing and checking all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM.
If it is not possible to replace the MB (SSB) board, it is necessary to check the serviceability of its elements - Cpu - MST6E182VG-LF-Z, Spi Flash - CFEON032B-104H1P. Defective components must be replaced.
If there is no tuning to local TV channels, you should make sure that the supply voltage of the varicaps (30-33V) and other supply voltages are present on the ET-9Z2E-CF106H tuner terminals.
Owners of the STV-LC32660FL TV are advised to contact only qualified specialists with experience for repair! Attempts to repair yourself without the appropriate knowledge and skills can lead to serious negative consequences!

Attention! SUPRA STV-LC32660FL LED TV panel T320HVN01.V2 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.
