SUPRA STV-LC39663FL
General recommendations for TV LCD LED repair
Repair of electronic equipment usually begins with its external examination and diagnosis of a malfunction. In this case, you should inspect all the internal components of the SUPRA STV-LC39663FL TV, as well as the external elements of the case. Based on visible external changes in the state of components, it is usually possible to determine the further direction of troubleshooting and localization of a defect before taking 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.
In the case when the STV-LC39663FL does not turn on, does not respond to the remote control and front panel buttons, does not blink lights and does not show any signs of operability, the power module is probably faulty in this case. If it is working properly with such manifestations, it is necessary to check the processor power regulator (converter) on the motherboard. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse in the power supply is broken, in most cases a breakdown of the power switch (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. You should also check the diodes of the rectifier bridge and the electrolytic capacitor of the mains rectifier filter.
Mos-Fet switches used in switching power supplies (SMPS) rarely fail without reasons that must be looked for by checking other circuit elements. Breakdown is often caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or breakdown of resistors in stabilization circuits. The PWM controller microcircuit can also cause the breakdown of the power switch of the converter.
Sometimes the SUPRA STV-LC39663FL 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 V390HJ1-P01 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).
In most cases when there is no backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or more LEDs do not work in one line, therefore, they are punctured and should be replaced.
It should be remembered that it is not possible to determine an open circuit in the LED lines without disassembling the panels using a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
In cases of an attempt to repair the motherboard 5800-A8M480-OP10 (VER.00.07), it is necessary to check the performance of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
In cases of attempts to repair the MB (SSB) board, it is necessary to check the serviceability of its elements - FLASH: EN25Q32 which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its pins with the board (indicated by warming up).
Before changing the ET-9Z2E-CF106H tuner, if it is not possible to tune to TV channels, you should make sure that there are supply voltages, including the power supply for varicaps (30-33V), which must be measured at the corresponding terminals of the tuner.
Remember! Attempts to self-repair the SUPRA STV-LC39663FL TV by users without appropriate qualifications and the necessary experience can lead to serious negative consequences!

If the SPI FLASH Winbond software fails, we recommend replacing the microcircuit with a new one. In addition, faulty Winbond microcircuits can sometimes recover for a while after warming up with a soldering station or even a lighter, which is enough to read its standard contents.

Attention! SUPRA STV-LC39663FL LED TV panel V390HJ1-P01 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.
