General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular PHILIPS 40PFL5616 / 60, it is advisable to start with a careful external examination of internal and external elements. According to some external signs of a change in the state of some elements, it is sometimes possible to make assumptions about the nature of the defect, as well as determine the further direction of the troubleshooting. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
In the case when the 40PFL5616 does not turn on, does not respond to the remote control and the front panel buttons, does not blink bulbs and does not show any signs of operability, the PLDE-P017A power supply module is probably defective in this case. If it is serviceable under such manifestations, it is necessary to check the power supply stabilizer (converter) of the processor on the motherboard.When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
Power switches in pulsed power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The reason may be a malfunction of the PWM controller chip LNK358, MAP3205, which can only be checked by replacing with a new or obviously working one.
If the PHILIPS 40PFL5616 does not have an image, but there is sound and the TV is controlled by the remote control, a malfunction in the backlight circuits of the LK400D3LB83 panel is likely. The LEDs or the power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the LED driver, and check the LEDs, connecting obviously known good diagnostics.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
In cases of attempts to repair the motherboard 715G4722-M1B-000-005B, it is necessary to check the operability of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Verification or replacement of elements MT5366CVCG, MT5135AE, TMDS351, STA339B requires the necessary training and professional skills in repairing modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
Attention! For users and owners of 40PFL5616 TVs who do not have the appropriate qualifications, knowledge and experience, we categorically do not recommend attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

Main features of the PHILIPS 40PFL5616 device:
Installed matrix (LED panel) LK400D3LB83.
The matrix control uses the Timing Controller (T-CON) DUNTK4918TP.
The necessary supply voltages for all nodes of the PHILIPS 40PFL5616 TV are generated by the PLDE-P017A power module or its analogs using LNK358, MAP3205 microcircuits.
MainBoard - the main board (motherboard) is a module 715G4722-M1B-000-005B, using chips MT5366CVCG, MT5135AE, TMDS351, STA339B and others.
The ENV57U03D5F tuner provides television reception and channel tuning.
