General recommendations for TV LCD LED repair
Diagnosis of malfunction and repair of RUBIN RL-22SE5F, like other electronic devices, is recommended to begin with an external examination 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. 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 to guess the causes and possible consequences of the malfunction.
In cases where the RUBIN RL-22SE5F 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 (a typical defect in some RUBIN TV models). When diagnosing and repairing the power supply, first of all, you should replace the swollen capacitors of the secondary rectifier filter and check the fuse and, if it is broken, you must 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.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur without 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 broken resistors or punctured semiconductor elements in the stabilization circuits. Possible defect of the PWM chip from the manufacturer.
If, when you turn on the TV, the image appears and immediately disappears, or is absent initially when turned on, but there is sound and other functions work, there is a high probability of a malfunction of the LED driver (the power converter for the backlight LEDs of the M215HGE-L2-M panel). In such cases, the general power module is also subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the LED driver should be checked.
In most cases when there is no backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or more LEDs do not work in one line, therefore, they are punctured and should be replaced.
It is impossible to identify an open circuit in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and a voltage of several tens of volts is required to open their junctions. Ideally, a current source is suitable for such purposes.
The TP.VST59.P63 motherboard must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or is on continuously. In such cases, if the converters or power regulators of the microcircuits are working, it may be necessary to update the software.
When repairing an MB board, you need to check its SPI Flash components: W25Q32DVSIC. Defective elements must be replaced. If BGA chips are installed, their failure is usually localized by warming up.
Attention to users! Independent repair of the RUBIN RL-22SE5F TV without appropriate qualifications and experience can lead to its complete non-repairability!

The appearance of MainBoard TP.VST59.P63 is shown in the figure below:TP.VST59.P63
The TP.VST59.P63 motherboard is combined with a power supply module and is an independent device based on the TSUMV59Xxx multifunctional processor. Repair of such a board must begin with checking the power supply elements, as well as the operability of voltage converters and linear stabilizers necessary to provide power to certain processor nodes, in particular: core power supply + 1.2V, built-in DDR + 1.8V memory and stand-by mode node by 3.3V. The supply voltage of the LCD panel is 5V or 12V, depending on the type of panel used, it is necessary to check directly on the LVDS connector.
TP.VST59.P63 can be used in TVs:
RUBIN RL-22SE5F (Panel M215HGE-L2-M), RUBIN RB-24SE5F (Panel M240HTN01.2).
Key features of the RUBIN RL-22SE5F device:
Installed matrix (LED panel) M215HGE-L2-M.
The power module is combined with the MainBoard and is made according to the AC / DC flyback voltage converter using LD7536R microcircuits.
MainBoard - the main board (motherboard) is a TP.VST59.P63 module, using CPU chips: TSUMV59XE-Z1, SPI Flash: W25Q32DVSIC; SOUND: YD1517P and others.
