General repair guidelines for TV LCD LED
Possible malfunctions
- The PHILIPS 46PFL6606H TV does not turn on and does not show any signs of operability at all. There is no reaction to the remote control and control buttons from the front panel.
In some of these cases, a malfunction is detected in the HR-PSL46-2-MED power module. It is necessary to measure its output voltages and, in case of their absence, check the serviceability of power switches and rectifier diodes in the converters for possible breakdown.
In the event of breakdowns in the secondary circuits of the converter, it can usually fail in short circuit mode, and in the event of a short circuit in the power elements of the primary circuit, the mains fuse or current sensor at the source of the key most often breaks.
Mos-Fet power switches, used in switching power supplies, sometimes fail due to a malfunction of any other elements that can put it out of operation in key mode or create an excess of the maximum permissible parameters of the switch. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. PWM controllers, in the absence of visible damage or frank short-circuit between the terminals, are checked by replacing with new, or obviously working.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
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 test 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 313912364945 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software). Board repair and chip replacement PNX85500, M25P05, TPA3123D2PWP 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.
If the TV works normally with external devices but does not tune into television channels, the TH2627 tuner 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.
TV users and owners need to remember that attempts to independently repair a PHILIPS 46PFL6606H TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

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 46PFL6606H 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.
