General repair guidelines for TV LCD LED
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should inspect all the internal components of the TV SUPRA STV-LC22810FL, as well as the external elements of the housing. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. Experienced repairmen are often aware of the causes of the defect and the possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
Malfunctions of the power module can be expressed in different ways, for example, SUPRA STV-LC22810FL does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the stabilizer (converter) of the processor power may turn out to be faulty. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should begin by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
In most cases, key breakdowns in switching power supplies (IIPS) do not occur for no 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 dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
If the SUPRA STV-LC22810FL TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the M215HGE-L21 Rev.C1 panel is likely. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for excessive ESR.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
It is impossible to detect a break in the line of LEDs without disassembling the panel with a simple multimeter. LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes.
The motherboard T.VST59.62 should be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up constantly. In such cases, if the converters or power stabilizers of the microcircuit are working, a software update may be necessary.
In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its CPU chips TSUMV59XE, Flash GD25Q32 and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
In the absence of tuning to local television channels, you should make sure that there are supply voltages at the terminals of the tuner CDT-3NP5I1-10.
Owners and users of the SUPRA STV-LC22810FL TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

The appearance of MainBoard T.VST59.62 is shown in the figure below:T.VST59.62
It is advisable to start repairing the T.VST59.62 motherboard based on the TSUMV59Xxx multifunction processor by checking the performance of linear voltage stabilizers or voltage converters necessary to provide power to the processor nodes - 1.2V core power, DDR 1.8V memory and Stand-by 3.3V mode . If there is no image, but the display backlight is working properly, you should check the power supply voltage of the LCD panel 5V or 12V, depending on the type of panel used.
