General recommendations for TV LCD LED repair
SUPRA STV-LC46500FL, like other TVs, it is advisable to start repairing with a careful examination of the external and internal elements and modules. Many visible changes in the state of elements make it possible to determine the further direction of troubleshooting and localization of the defect. Elements with visible damage, for example, capacitors swollen after electrolyte boiling, charred resistors in certain nodes of the circuit, as well as ring cracks in the solders, will help the master guess the causes and possible consequences of the malfunction.
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. In general, first of all, it is necessary to check the electrolytic capacitors of the filters of the secondary rectifiers and the fuse at the mains input. If it is cut off, then the diodes of the rectifier bridge and the key transistor of the converter, which can be located either on a separate heatsink or integrated with a PWM controller into a common microcircuit, should be checked for a breakdown of PN junctions. Options are possible.
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.
If, when SUPRA STV-LC46500FL is turned on, there is no image, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the V460HJ1-PE1 panel backlight LED circuit, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the common power supply.
It is often necessary to disassemble the panel to check the health of the LEDs, as well as the contact connections in the connectors and solders.
When diagnosing, it must be borne in mind that it is impossible to check for an open in the circuit of the LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally a current source.
Diagnostics and repair of the T.MS18VG.72 motherboard is carried out by checking the functionality of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Repair of the board and replacement of CPU: TSUMV59XE, FLASH: SPI 25Q32 microcircuits, are performed if the necessary equipment and the corresponding element base are available. Malfunctions associated with the use of BGA soldering technologies can be localized by warming up.
The malfunction of the CDT-3NP5I1-10 tuner is established after checking the software and all supply voltages at its terminals.
We remind users again! Attempts to repair the SUPRA STV-LC46500FL TV without proper qualifications and experience can lead to its complete non-repairability!

Attention! SUPRA STV-LC46500FL LED TV panel V460HJ1-PE1 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.
