General recommendations for TV LCD LED repair
Possible malfunctions
- The TELEFUNKEN TF-LED32S11 TV does not turn on, does not respond to the remote control and control panel buttons, the indicators do not light up or flash.
In this case, first of all, you should check the operability of the main power source - the AC / DC voltage converter, all the elements of which are located on the MainBoard TP.VST59S.PC1. It is necessary to measure its output voltages, and in the event of their absence (full or partial), the serviceability of the power switches of the converters and rectifier diodes should be checked for a possible short circuit.
In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in an emergency mode of short circuit without output voltages, and with a short circuit in the elements of the primary circuit, the mains fuse most often breaks off immediately and, less often, the current sensor in the source of the key.
Mos-Fet power switches used in switching power supplies sometimes fail due to a malfunction of any other elements that can disable it in the key mode, or create an excess of the maximum permissible key parameters. These can be elements supplying a PWM regulator, frequency setting or damper circuits, or elements of negative feedback in the stabilization circuit. PWM controllers PWM SOT23-6, in the absence of visible damage or outright short circuits between the terminals, are checked by replacing them with new ones, or knowingly working properly.
- There is no picture, but there is sound and reaction to commands from the remote control. Or the image appears immediately after switching on and disappears.
A malfunction is usually in these cases most likely in the backlight units of the display matrix. The reason can 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.
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 TV does not turn on, the indicator signals the standby or operating mode, or blinks.
Repair or diagnostics of the TP.VST59S.PC1 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 - SPI Flash: GD25Q32BS, SOUND: TPA3110LD2 with new or known good ones. In cases where BGA technologies are used, defects are usually localized by heating.
In cases where there is no tuning for terrestrial or cable TV channels, you should make sure that the software is correct, as well as in accordance with the nominal supply voltages at the NoName tuner terminals. 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.
Remember! Attempts to self-repair the TELEFUNKEN TF-LED32S11 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!
The appearance of MainBoard TP.VST59S.PC1 is shown in the figure below:TP.VST59S.PC1
TP.VST59S.PC1 can be used in TVs:
FUSION FLTV-40K62 (Panel 720p HD 1366x768), HYUNDAI H-LED32V26 (Panel ST3151A04-3 / (CS)), TELEFUNKEN TF-LED32S26 (Panel MT3151A04-1-XC-9), TELEFUNKEN TF-LED32S11 (Panel E32-9100).
The main features of the TELEFUNKEN TF-LED32S11 device:
Installed matrix (LED panel) E32-9100.
To power the backlight LEDs, a converter combined with the TP.VST59S.PC1 main board is used, controlled by the OB3350CP PWM controller.
The power module is combined with the MainBoard and is made according to the AC / DC flyback voltage converter using PWM SOT23-6 microcircuits.
MainBoard - the main board (motherboard) is a TP.VST59S.PC1 module, using SPI Flash chips: GD25Q32BS, SOUND: TPA3110LD2 and others.
Tuner NoName provides reception of television programs and tuning to channels.

Attention! The panel E32-9100 of the TELEFUNKEN TF-LED32S11 LED TV 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 non-repairable.
