RUBIN RB-32SE9
General recommendations for TV LCD LED repair
Possible manifestations of defects
- RUBIN RB-32SE9 TV does not turn on, does not respond to the remote control and control panel buttons, does not light or blink indicators.
First of all, in such cases, you should make sure that the common switching power supply (SMPS) - the AC / DC voltage converter of the mains voltage - is working. All source elements in this TV model are located on the MainBoard CV59SH-E32. It is necessary to make sure that its output voltages are present and, if they are completely absent, check the power switches and rectifier diodes for a possible short circuit.
In the event of diode breakdowns in the secondary circuits, the converter can operate in an emergency mode of short circuit without output voltages, and with a short circuit in the power elements of the primary circuit, the mains fuse and / or the current sensor in the source of the key usually breaks off.
Breakdown of power switches (MosFet) in switching sources is sometimes caused by malfunctions of other circuit elements, for example, in the circuits supplying the PWM controller, frequency setting or damper, as well as in the circuits of Negative Feedback (OOS) stabilization. PWM regulators (PWM) PWM SOT23-6, if they do not have visible damage to the case and an open short circuit between the pins, are usually checked by replacing.
- There is no image, there is sound, it reacts to the remote control, the channels are switched. In some cases, the image appears when turned on and disappears immediately.
A malfunction is usually in these cases most likely in the backlight units of the display matrix. The reason for this may be an open circuit in the LED circuit, or a problem in stabilizing their power supply.
To check the LED strips for breakage without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter; a voltage of the order of several tens of volts is required.
- The indicator blinks or is on constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the CV59SH-E32 motherboard should begin with checking the stabilizers and power converters necessary to power the microcircuits and matrix. If necessary, you should update or replace the software (software). Often the MB (SSB) board needs to be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - CPU: TSUM59XUS, SPI FLASH: GD25Q32, Audio: APA2614 and replace the failed chips with new ones. Some malfunctions may be associated with the use of BGA soldering technologies in modern Main Board. Usually such defects are detected by local heating of the chip.
If there is no reception of television channels, but the TV is working properly from external devices, first of all, you need to check the supply voltage of the RDA5156 tuner and update the software. I2C communication pulses must be monitored with an oscilloscope.
Attention to users! Independent repair of the RUBIN RB-32SE9 TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

Attention! The panel of the RUBIN RB-32SE9T2C 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.
