General recommendations for TV LCD LED repair
Repair of the RUBIN RB-24SE5F TV should begin with a careful external examination of all its constituent elements and modules. It often happens that visible damage to elements or connections helps determine the direction of troubleshooting. If charred resistors, swollen electrolytic or sintered capacitors, ring cracks in the soldering of the terminals of transformers or heating elements are found, it is advisable to establish the causes and consequences of the malfunction, as well as to check the connected elements and assemblies.
In cases where the RUBIN RB-24SE5F 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 of some RUBIN TV models). In general, first of all, it is necessary to check the electrolytic capacitors of the filters of the secondary rectifiers and the fuse at the mains input. If it is cut off, then the diodes of the rectifier bridge and the key transistor of the converter, which can be located either on a separate heatsink or integrated with a PWM controller into a common microcircuit, should be checked for a breakdown of PN junctions. Options are possible.
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 the RUBIN RB-24SE5F has no picture, but there is sound and the TV is controlled from the remote control, there is likely a malfunction in the M240HTN01 panel backlight circuits. 2. The LEDs or the power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to make sure that the electrolytic capacitors of the rectifier filter supplying the LED driver are in good working order, and check the LEDs by connecting those that are known to be working for diagnostics.
It is often necessary to disassemble the panel to check the health of the LEDs, as well as the contact connections in the connectors and solders.
When diagnosing, it must be borne in mind that it is impossible to check for an open in the circuit of the LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally a current source.
Diagnostics and repair of the TP.VST59.P63 motherboard is carried out by checking the functionality of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Repair of the board and replacement of CPU: TSUMV59XE-Z1, SPI FLASH: GD25Q32 microcircuits are made with the necessary equipment and the corresponding element base. Malfunctions associated with the use of BGA soldering technologies can be localized by the warm-up method.
Attention to users! Independent repair of the RUBIN RB-24SE5F TV without proper 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 required 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).
The main features of the RUBIN RB-24SE5F device:
Installed matrix (LED-panel) M240HTN01. 2.
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: GD25Q32, SOUND: YD1517P and others.

Attention! The M240HTN01.2 panel of the RUBIN RB-24SE5F LED TV is an expensive and unreliable element.
Do not allow any impact on the glass and pressure on the screen surface to avoid damage to the LED panel!
It is also unsafe for liquid to spill onto the screen. Sometimes one drop is enough if it drips down the glass onto the cables to make the TV unrepairable.
