General repair guidelines for TV LCD LED
Possible manifestations of defects
- The PHILIPS 55PFL5507T 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 DPS-180AP-11A is found to be faulty. It is necessary to measure its output supply voltages, and in case of their absence, check the serviceability of the power switches of the converters (STP5NK80ZFP) and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In the event of a short circuit in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the elements of the primary circuit, the mains fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM circuits (PWM) 2QS02G, DDA009, DDA010 are usually checked by replacing with new ones, or obviously working.
- There is no image, there is sound, it is responding to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
The most likely in these cases is a malfunction of the LED backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can check each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN junction indirectly indicates a LED-a
- The TV does not turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the motherboard 313929716961 should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - TAS5731, SPARTAN-6, RT8293AH and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
If the TV works normally with external devices, but does not tune into television channels, the tuner SUT-RE214AN may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding conclusions. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the cause of the inoperability of the tuner may be a software failure.
It should be remembered! Attempts to independently repair the PHILIPS 55PFL5507T 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-serviceability of the device!

Main features of the PHILIPS 55PFL5507T device:
Installed matrix (LED-panel) LTA550HW03.
The matrix control uses the Timing Controller (T-CON) PH_120PSQBC4LV1.0.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the DDA010 PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 55PFL5507T TV are generated by the DPS-180AP-11A power supply module or its analogs using 2QS02G, DDA009, DDA010 microcircuits and STP5NK80ZFP power switches.
MainBoard - the main board (motherboard) is a module 313929716961, using chips TAS5731, SPARTAN-6, RT8293AH and others.
The SUT-RE214AN tuner provides TV reception and channel tuning.
