General recommendations for TV LCD LED repair
Possible malfunctions
- The ROLSEN RL-39D1305F TV does not turn on, does not respond to the remote control and control panel buttons, does not light or blink indicators.
In such cases, the AC / DC converter of the mains voltage, which is combined with the main board TP.VST59.P83, is often faulty. It is then necessary to measure its output voltages and, if they are absent, the power switches (7N60) and rectifier diodes of the converters should be checked for the probability of a short circuit.
In case of breakdowns of semiconductors in the secondary circuits, the converter can usually work in an emergency in the short-circuit mode, and with a short circuit in the power elements of the primary circuit, the mains fuse often breaks.
Breakdown of Mos-Fet switches used in switching power supplies is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM regulator, in frequency-setting or damper circuits, as well as in negative feedback stabilization. PWM microcircuits (PWM) LD7536 (PWM SOT23-6) are usually checked by replacing them with new ones, or known to be working properly.
- There is no image, there is sound, it reacts to the remote control. Or the image may appear for a second when turned on and disappear immediately.
The malfunction in most of these cases is found in the nodes and elements of the LED panel backlighting. The reason may be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
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. You can open the panel and check each LED separately. Usually, Chinese multimeters lightly light one 3-volt LED if you connect the probes to it in the forward direction (red probe to the anode, black to the cathode). For dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as an indicator of the LED health. In the event of a malfunction of the LED, its zener diode will either be cut off, or broken through in the SC.
- The TV does not go into operation, does not respond to the remote control. The indicator on the front panel is on or blinking.
Repair or diagnostics of the TP.VST59.P83 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 the event of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - CPU: TSUMV59XE, SPI FLASH: W25Q32BVS, AUDIO: TPA3110D2 and replace the failed chips with new ones. Some malfunctions may be associated with the use of BGA soldering technologies in modern Main Board. Typically, such defects are detected by local heating of the chip.
If there is no reception of TV channels, but the TV is working properly from external devices, first of all, you need to check the supply voltage of the CDT-3NP5I1-10 tuner and update the software. I2C communication pulses must be monitored with an oscilloscope.
Attention to users! Self-repair of the ROLSEN RL-39D1305F TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

The appearance of MainBoard TP.VST59.P83 and voltage measurements at test points are shown in the figure below:TP.VST59.P83
The TP.VST59.P83 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 + 1.2V, built-in DDR + 1.8V memory and standby 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.

Attention! Panel V390HJ1-P02 Rev. C1 LED TV ROLSEN RL-39D1305F is an expensive and unreliable element.
Do not allow any impacts 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.
