General recommendations for TV LCD repair
It is recommended that you start diagnostics and repair of SUPRA with the V1I12 chassis, as well as other electronic devices, with an external inspection of the external and internal elements. According to some external signs of a change in the state of some elements, it sometimes becomes possible to make assumptions about the nature of the defect, as well as to determine the further direction of troubleshooting. 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.
Malfunctions of the power module K0A078M Rev: 1.0 can be expressed in different ways, for example, SUPRA STV-LC2615FD does not turn on at all and the control lamps on its front panel do not light up or blink, all signs of operability are absent. It should be noted that the processor power regulator (converter) may be faulty with the same external manifestations. 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.
As a rule, switches in switching power supplies (SMPS) are quite reliable and rarely fail without reasons that should be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM microcircuit is checked by replacing it with a known good one.
If, when SUPRA STV-LC2615FD is turned on, there is no image, or it appears for a second and disappears completely, but there is sound, most likely either the backlight lamps or their power converter (inverter) are faulty. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the common power supply. When turning off the protection in order to ensure the possibility of diagnosing a malfunction, special care should be taken, and after all repair work is completed, it is imperative to restore the circuits and the operation of the inverter protection for the further safe operation of the TV.
On the T.MT8222.1B motherboard, in case of malfunction, you should first check the operability of all stabilizers or power converters of microcircuits and, if necessary, update the software (software). Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment.

Remember! Attempts to repair the SUPRA STV-LC2615FD TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!
