General repair guidelines for TV LCD LED
Possible malfunctions
- The PHILIPS 46PFL3008T TV does not turn on, does not respond to the remote control and the control panel buttons, does not light up or blink indicators.
Most often, with such manifestations, the main power module 715G5778-P02-000-002R turns out to be faulty. It is necessary to verify the presence of its output voltages and, if they are completely absent, check the power switches (8NM50N, 24MN60N) and rectifier diodes for a probable short circuit.
In case of diode breakdowns in the secondary circuits, the converter can operate in emergency short-circuit mode without output voltages, and during short circuit in the power elements of the primary circuit, the mains fuse and / or current sensor at the source of the key usually 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 SSC9522S (PWM Resonant), R2A20133ESP (PFC), A6069H (Standby, 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, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
In most of these cases, a malfunction is detected in the nodes and backlight elements of the LED panel. 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 TV does not turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the 715G5675-M01-000-005K motherboard should begin by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). Sometimes it is necessary to check or replace (if necessary) the elements of the MainBoard board - MTK5580CPOI, TC58NVG1S3ETAI0, CAT24C128WI, STA381BWTR. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
Before changing the TDSY-G230D tuner, if it is not possible to tune to television channels, make sure that there are supply voltages that must be measured at the corresponding tuner pins and checked for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
Once again, remind users! Attempts to self-repair a PHILIPS 46PFL3008T TV without the appropriate qualifications and necessary experience can lead to its complete non-repairability!

The appearance of the power supply
Main features of the PHILIPS 46PFL3008T device:
Installed matrix (LED panel) TPT460H1-HM01 Rev-C1J code 195.
The matrix control uses the Timing Controller (T-CON) A60EDGEC2LV0.2.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the PF7900S, PF7700A PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 46PFL3008T TV are generated by the 715G5778-P02-000-002R power supply module or its analogs using SSC9522S (PWM Resonant), R2A20133ESP (PFC), A6069H (Standby and power switches type 8NM50N, 24MN60N microchips).
MainBoard - the main board (motherboard) is a module 715G5675-M01-000-005K, using microchips MTK5580CPOI, TC58NVG1S3ETAI0, CAT24C128WI, STA381BWTR and others.
