General recommendations for TV LCD LED repair
Possible malfunctions
- TELEFUNKEN TF-LED65S37T2SU 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 control buttons.
In some of these cases, the main switching power supply, the TV5502-ZC02-01 module, is faulty. It is then necessary to measure its output voltages and, if they are absent, the power switches (13NM60 (PFC), BYC8X-600P) and the rectifier diodes of the converters should be checked for the probability of a short circuit.
In case of diode breakdowns in the secondary circuits, the converter can operate in an emergency mode of short circuit without output voltages, and in the event of 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.
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) TEA1716, SY8113B, in the absence of external damage and a short circuit between the terminals, are checked by replacing them with known good ones.
- There is no picture, 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.
As a rule, in such cases there is no display backlight. The reason for this may be an open circuit in the LED circuit, or a problem in stabilizing their power supply.
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 LED health. In the event of a malfunction of the LED, its zener diode will either be cut off, or broken through in the K / Z.
- 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 MS65860-ZC01-01 motherboard should begin with checking the stabilizers and power converters required to power the microcircuits and matrix. If necessary, you should update or replace the software (software). When repairing an MB board, you need to check its e-MMC components: THGBMHG6C1LBAI. Defective elements should be replaced. If chips with BGA soldering technology are used, the problem in its implementation is detected by local heating of the chip.
If 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 outputs. 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.
Attention to TV owners! Attempts to repair TELEFUNKEN TF-LED65S37T2SU by yourself are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the TELEFUNKEN TF-LED65S37T2SU device:
Installed matrix (LED panel) T650QVR07.2.
Matrix control uses Timing Controller (T-CON) 65T53-C01.
To power the backlight LEDs, a converter combined with a power supply is used, controlled by an OCP8128 PWM controller. The 60R360Q type keys are used as power elements of the LED driver.
The formation of the necessary supply voltages for all nodes of the TELEFUNKEN TF-LED65S37T2SU TV is carried out by the TV5502-ZC02-01 power module, or its analogs using TEA1716, SY8113B microcircuits and power switches of the 13NM60 (PFC), BYC8X-600P type.
MainBoard - the main board (motherboard) is an MS65860-ZC01-01 module, using e-MMC chips: THGBMHG6C1LBAI and others.
Tuner NoName provides reception of television programs and tuning to channels.

Attention! Panel LED TV TELEFUNKEN TF-LED65S37T2SU 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.
