General repair guidelines for TV LCD LED
Possible malfunctions
- The TELEFUNKEN TF-LED39S11 TV does not turn on, does not respond to the remote control and control panel buttons, indicators do not light up and do not blink.
In this case, first of all, it is necessary to check the operability of the main power source - the AC / DC network voltage converter, all of whose elements are located on the MainBoard TP.VST59S.PB813 board. It is necessary to measure its output voltages, and in case of their absence (full or partial), it is necessary to check the serviceability of the power switches of the converters and rectifier diodes for the presence of a possible short circuit.
In case of breakdowns of semiconductors in secondary circuits, the converter can usually work abnormally in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse often breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke the excess of maximum current or voltage values. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) 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 with obviously good ones.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
Usually in such cases, a malfunction is detected in the backlight nodes of the LED panel. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of 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. By opening the panel, each LED can be checked separately. Typically, Chinese multimeters light up a single 3-volt LED, if you connect probes in the forward direction to it. In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the TP.VST59S.PB813 motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Sometimes it is necessary to check or replace (if necessary) the elements of the MainBoard - CPU: TSUMV59XUS, SPI Flash: GD25Q32B, TPA3110. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
If there is no reception of television channels, but the TV works properly from external devices, first of all you need to check the voltage of the tuner RAFAEL Micro R840 and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
TV users and owners need to remember that attempts to repair a TELEFUNKEN TF-LED39S11 TV independently without the appropriate qualifications and necessary experience can lead to serious negative consequences!

The appearance of MainBoard TP.VST59S.PB813 is illustrated in the figure below:TP.VST59S.PB813
The TP.VST59S.PB813 motherboard is combined with a power supply module. It is an independent device designed on the basis of the TSUMV59Xxx multifunction processor. The repair of such a card must begin by checking the supply batteries, as well as the proper functioning of the voltage converters and linear stabilizers, necessary to supply certain processor nodes, in particular: +12 V of central power, integrated DDR + 1.8 V of memory and by 3.3 V. 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.VST59S.PB813 can be used in televisions:
MYSTERY MTV-3217LW (Panel CX315DLEDM), SHIVAKI STV-32LED6 (Panel HV320WX2-206), SUPRA STV-LC28500WL (Panel ST2751A01-3), TELEFUNKEN TF-LED32S2 (Panel LSC320AN02), TELEFUNKEN TF-LED39S11 (Panel T390HVN04.2 E39-9100).
Main characteristics of the TELEFUNKEN TF-LED39S11 device:
Installed matrix (LED panel) T390HVN04.2 E39-9100.
The matrix control uses the synchronization controller (T-CON) T390HVD01.2.
To supply the LEDs for the backlight, a converter is used, associated with the main board TP.VST59S.PB813, controlled by the SN510P PWM controller.
The power module is combined with the MainBoard and is designed according to a reverse feedback AC / DC voltage converter using PWM SOT23-6 LD7536 microcircuits.
MainBoard - the motherboard (motherboard) is a TP.VST59S.PB813 module, using processor chips: TSUMV59XUS, Flash SPI: GD25Q32B, Audio: TPA3110 and others.
The RAFAEL Micro R840 tuner provides television reception and channel tuning.
