General repair guidelines for TV LCD LED
Possible malfunctions
- The PHILIPS 46PFL5606H TV does not turn on and does not show any signs of turning on, does not respond to the control buttons or to the remote control.
In some of these cases, the main switching power supply, the HR-PSL46-2-Med module, is faulty. It is necessary to measure its output voltages, and in case of their absence (full or partial), it is necessary to check the serviceability of the power switches of the converters and rectifier diodes for the presence of a possible short circuit.
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.
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 microcircuits are usually checked by replacement with new ones, or obviously working.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the LED strips, to open all the transitions of the LEDs, several tens of volts or more are needed, it is best to use a current source for such purposes. The breakage of several PN junctions connected in series cannot be detected with a multimeter or tester. In such cases, it is necessary to open the panel and check each LED. If your multimeter cannot open the LED transitions in forward bias, you can sometimes detect the presence of a PN junction of the protective zener diode by connecting the probes in the opposite direction. If the zener diode is broken or broken in short-circuit, then the LED is faulty and needs to be replaced.
- The indicator on the front panel blinks, the TV does not turn on in operating mode, it does not respond to the remote control.
Repair or diagnostics of the 715G4722-M1C-000-005X 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). When repairing an MB board, you need to check its components SI5403DC-T1-GE3, H5PS1G63EFR-G7C, AT24C02C, MT5135AE / A, STA339BWTR. 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.
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 ENV57U03D5F. 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.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Entrust repair to professionals with sufficient experience in the field of repair of electronic equipment.

The appearance of the power supply
Main features of the PHILIPS 46PFL5606H device:
Installed matrix (LED-panel) LK460D3LB93 code 144.
In matrix management, the CPWBX Timing Controller (T-CON) is used.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the OZ9902 PWM controller. As power elements of the LED driver, keys of the type AOD450, MDHT3N40 are used.
The necessary supply voltages for all nodes of the PHILIPS 46PFL5606H TV are generated by the HR-PSL46-2-Med power supply module or its analogs using FA5591, L6599, LNK362 (Stb) microcircuits and MDF11N60, KF5N50 type power switches.
MainBoard - the main board (motherboard) is a module 715G4722-M1C-000-005X, using chips SI5403DC-T1-GE3, H5PS1G63EFR-G7C, AT24C02C, MT5135AE / A, STA339BWTR and others.
The tuner ENV57U03D5F provides the reception of television programs and tuning to channels.
