General repair guidelines for TV LCD LED
Possible malfunctions
- The PHILIPS 50PUS6809 TV does not turn on at all. The control lights do not light or flash. The TV on the remote control and the control panel buttons do not respond.
Most often, with such manifestations, the main power module 715G6555-P02-000-002M is found to be faulty. In the absence of the necessary supply voltages in the secondary circuits of the converters, it is necessary to check the power switches (TK16A60W, TK13A65U, TK10A60D) and rectifier diodes for a possible partial or complete breakdown.
In case of any breakdown of semiconductors in the secondary circuits, the converter can usually work normally in emergency short circuit mode. There are no output voltages. And with a short circuit in the power elements of the primary circuit, as a rule, the mains fuse breaks and less often the current sensor at the source of the key.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback circuits (OOS) of stabilization. PWM controllers (PWM) LD7591T, LD7752B, SSC9522S, if they do not have visible damage to the case and open fault between the terminals, are usually checked by replacement.
- There is no image, there is sound, it responds to the remote. Or the image may appear for a second when turned on and immediately disappears.
In such cases, the most likely malfunction of the LED backlight elements. 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.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Typically, Chinese multimeters light up a single 3-volt LED, if you connect the probes in the forward direction to it (red probe to the anode, black to the cathode). 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 indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the 715G6842-M0C-000-005N motherboard should be started by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). When repairing an MB board, it is necessary to check its components MT5591IVDJ, STA381BW. Defective items should be replaced. If chips with BGA soldering technology are used, a problem in its implementation is detected by the local heating of the chip.
Before replacing the TDSY-G380D, SUT-ZE221ZN tuner, if there is no tuning for the channels, you must first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via I2C
We recommend the owners of the 50PUS6809 TV for repair only to qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!

The appearance of the power supply
Main features of the PHILIPS 50PUS6809 device:
Installed matrix (LED-panel) V500DK2-KS1 Rev.C8.
The matrix control uses the Timing Controller (T-CON) V500DK2-CKS2.
The LED driver C500S01E02A is used to power the backlight LEDs.
The necessary supply voltages for all nodes of the PHILIPS 50PUS6809 television are generated by the 715G6555-P02-000-002M power supply module or its analogs using the LD7591T, LD7752B, SSC9522S microcircuits and power switches of the TK16A60W, TK13A65U, TK10A60D type.
MainBoard - the main board (motherboard) is a module 715G6842-M0C-000-005N, using chips MT5591IVDJ, 24C128, STA381BW and others.
The tuner RE231ZN & RE221ZN provides reception of television programs and tuning to channels.
