General recommendations for TV LCD LED repair
RUBIN RB-22SE9FT2C TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. It often happens that visible damage to elements or connections helps determine the direction of troubleshooting. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred layer of paint on the resistors - all this for the repairman can be a significant clue in assumptions about the causes and consequences of a malfunction.
If RUBIN RB-22SE9FT2C does not turn on, no indicator lights on the front panel will light up or blink, therefore, there is a very high probability of a power module malfunction. In some cases, only the processor power regulator may be faulty. It is advisable to start diagnostics of the power supply module by checking the condition of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. In the event that the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in a breakdown state in such situations.
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 dry 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 RUBIN RB-22SE9FT2C, there is no image, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the LED circuit of the backlight of the M215HTN01.1 CX215LEDM HD panel, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the common power supply.
A malfunction in the backlight circuits often occurs due to an open circuit in the power supply circuit of the LED lines. It is required to disassemble the panel and check the LEDs themselves, the ration of their conclusions, as well as the reliability of the connections in the connectors and the ration of the connector pins.
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.
Diagnostics and repair of the T.SIS231.T65 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.
In cases of attempts to repair the MB (SSB) board, it is necessary to check the serviceability of its elements - Spi Flash: 25Q64 which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its pins with the board (detected by warming up).
Attention! Users and owners of RB-22SE9FT2C TVs who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from trying to repair themselves in order to avoid negative consequences that can lead to the complete non-repairability of the device.

Attention! The M215HTN01.1 panel of the RUBIN RB-22SE9FT2C 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.
