General recommendations for TV LCD LED repair
Diagnostics of malfunctions and repair of SUPRA STV-LC32K800WL, like other electronic devices, it is recommended to begin with an external examination of external and internal elements. It often happens that visible damage to elements or connections helps determine the direction of troubleshooting. In some cases, defective elements are visible to the naked eye, for example, charred resistors or swollen sintered capacitors, or electrolytic ones in rectifier filters. The formed ring cracks in the soldering of the terminals of transformers or heating circuit elements are also frequent sources of many malfunctions with a variety of external manifestations.
In cases where the SUPRA STV-LC32K800WL TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink, and there are no sounds and no signs of operation when turned on, the power module is most likely faulty or there is no power processor on the motherboard (typical defect of some SUPRA TV models). When diagnosing and repairing the power supply, first of all, replace the swollen capacitors of the secondary rectifier filter and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module - rectifier diodes and transistors in the primary circuit.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (SMPS) it does not fail by itself without reasons that should be looked for by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If SUPRA STV-LC32K800WL has no picture but sound, the HV320WX2-201 panel backlight LEDs or their power converter may be faulty. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are in good working order.
Often, in the absence of backlighting, disassembly of the panel is required. It is necessary to check the serviceability of the LED transitions, as well as the reliability of the contact connections in the lines and connectors.
To check the LED strips for breakage without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter; a voltage of the order of several tens of volts is required.
In cases of attempts to repair the motherboard T.MS18VG.72 (T.VST59.A5), it is necessary to check the operation 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.
Often the MB (SSB) board needs to be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - CPU TSUMV59XE-Z1-SB, Flash W25Q32BV and replace the failed chips with new ones. Some malfunctions may be associated with the use of BGA soldering technologies in modern Main Board. Typically, such defects are detected by local heating of the chip.
If you suspect a malfunction of the CDT3NP511-10 tuner, first of all you need to make sure that there is a supply voltage at the corresponding output of the tuner.
Owners of the STV-LC32K800WL 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!
