General repair guidelines for TV LCD LED
Possible malfunctions
- SUPRA STV-LC24LT0010W does not turn on, does not respond to buttons and remote control, indicators on the front panel do not light up and do not blink.
In such cases, the AC / DC voltage converter, which is combined with the main board TP.MS3463S.PA63, is often faulty. It is necessary to measure its output supply voltages, and in case of their absence, check the serviceability of the power switches (TO-252) of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In case of breakdowns in the secondary circuits, the converter, as a rule, can emergency work in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse usually breaks.
The breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in the circuits supplying the PWM controller, frequency-setting or damper ones, as well as in the circuits of Negative Feedback (OOS) stabilization. PWM controllers (PWM) PWM SOT23-6, if they do not have visible damage to the case and open short circuit between the terminals, are usually checked by replacement.
- There is no image, the screen is black, there is sound, with external illumination of the screen, you can sometimes see barely noticeable outlines of the image.
The most likely in these cases is a malfunction of the LED backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
- The TV does not turn on, the indicator signals standby or working mode, or blinks.
Repair or diagnostics of the TP.MS3463S.PA63 motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the elements SPI FLASH: GD25Q64, AUDIO: YD1517P. BGA chip malfunctions are usually easy to detect by warming up.
Before replacing the XF-3SDT-H tuner, if there is no tuning for the channels, first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
Owners and users of the SUPRA STV-LC24LT0010W TV should 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!

Key Features of SUPRA STV-LC24LT0010W:
Installed matrix (LED panel) V236BJ1-P01.
To power the backlight LEDs, a converter is used, combined with the TP.MS3463S.PA63 main board, controlled by the SN51DP PWM controller. As power elements of the LED driver, keys of the TO-252 type are used.
The power module is combined with the MainBoard and is made according to the flyback AC / DC voltage converter circuit using PWM SOT23-6 microcircuits and TO-252 type power switches.
MainBoard - the main board (motherboard) is a module TP.MS3463S.PA63, using chips SPI FLASH: GD25Q64, AUDIO: YD1517P and others.
The XF-3SDT-H tuner allows you to receive television programs and tune to channels.

Attention! The V236BJ1-P01 panel of a SUPRA STV-LC24LT0010W LED TV is an expensive and unreliable element.
Avoid any impact on the glass and pressure on the surface of the screen to avoid damage to the LED panel!
It is also unsafe to get liquid on the screen. Sometimes one drop is enough if it flows down the glass onto the cables so that the TV becomes unrepairable.
