ROLSEN RL-39D1307
General recommendations for TV LCD LED repair
Possible manifestations of malfunctions
- ROLSEN RL-39D1307 TV does not turn on. There are no signs of operability. The indicators on the front panel do not light or blink, the TV does not respond to the remote control and control buttons.
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 necessary to make sure that its output voltages are present and, if they are completely absent, check the power switches (7N60) and rectifier diodes for a possible short circuit.
In case of breakdowns in the secondary circuits, the converter, as a rule, can operate in an emergency mode in the short-circuit mode, and in the event of a short circuit in the power elements of the primary circuit, the mains fuse is usually cut off.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements, which can disable it in key mode, or provoke an excess of the maximum current or voltage values. These can be circuits supplying the PWM controller, damper or frequency setting circuits, or OOS (negative feedback) elements in the stabilization circuit. PWM controllers (PWM) PWM SOT23-6 LD7536, in the absence of external damage and short circuit between the terminals, are checked by replacing them with a known good one.
- 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 most likely problem in these cases is a malfunction of the LED backlight. 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 should be remembered that it is not possible to determine an open circuit in the LED lines without disassembling the panels using a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required. Then you need to open the panel and check each LED separately with a multimeter. If the capabilities of your multimeter do not allow opening the LED in the forward direction or dual LEds are used, then the PN transition of the emergency zener diode can indirectly serve as an indicator of serviceability. In the event of a malfunction of the LED-a, the PN-junction of the 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). In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - CPU: TSUMV59XE, SPI FLASH: W25Q32BVS, AUDIO: TPA3110D2 with new or known good ones. In cases where BGA technologies are used, defects are usually localized by heating.
If there is no tuning for terrestrial or cable TV channels, you should make sure that the software is correct, as well as that the supply voltages on the outputs of the CDT-3NP5I1-10 tuner match. It is also necessary to check with an oscilloscope the presence of pulses of data exchange between the tuner and the processor via the I2C bus.
We remind users again! Attempts to repair the ROLSEN RL-39D1307 TV on your own 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.
TP.VST59.P83 can be used in TVs:
