General repair guidelines for TV LCD LED
Possible malfunctions
- The PHILIPS 55PFS8109 TV does not turn on, does not respond to the remote control and the control panel buttons, the indicators do not light or flash.
In some of these cases, a fault is detected in the FSP143-4FS01 power module. It is necessary to measure its output voltages and, in case of their absence, check the serviceability of power switches (N-FET TO-220F) and rectifier diodes in the converters for possible breakdown.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often breaks.
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) PFC, PWM, 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, the screen is black, there is sound, with external illumination of the screen you can sometimes see barely noticeable outlines of the image.
Often in such cases, there is no 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, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the 715RLPCB0000000055 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). Board repair and replacement of chips DE3114-A1, 88DE6010, TDA8296HN, W25Q64FVSSIG are carried out with the necessary equipment, and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
In the absence of tuning to the channels of on-air or cable television, you should make sure that the software is correct, as well as in accordance with the ratings of the supply voltage at the terminals of the tuner PE631AN DVB-T2 & SAT. It is also necessary to check the presence of pulses of data exchange between the tuner and the processor via the I2C bus using an oscilloscope.
It should be remembered! Attempts to self-repair a PHILIPS 55PFS8109 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!

Main features of the PHILIPS 55PFS8109 device:
The matrix (LED panel) TPT550J1-HJ06 REV.SC1E is installed.
The matrix control uses the Timing Controller (T-CON) 14Y_VNB5_S120P2C4LV0.2.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a BD9479FV PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 55PFS8109 television are generated by the FSP143-4FS01 power supply module or its analogs using PFC, PWM microcircuits, and N-FET TO-220F type power switches.
MainBoard - the main board (motherboard) is a module 715RLPCB0000000055, using chips DE3114-A1, 88DE6010, TDA8296HN, W25Q64FVSSIG and others.
Tuner PE631AN DVB-T2 & SAT provides the reception of television programs and tuning to channels.
