General repair guidelines for TV LCD LED
Repair of the PHILIPS 32PFL3208T / 60 TV should begin with a careful external examination of all its components and modules. In some cases, visible external damage to the elements can indicate the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of electronic circuit nodes. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a significant clue in the assumptions about the causes and consequences of the malfunction.
In cases where the PHILIPS 32PFL3208T TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink, and there are no sounds and no signs of operability when turning on, the power supply module 715G5793-P01-000 is most likely faulty -002M 96590004021 or there is no processor power on the motherboard (a typical defect of some PHILIPS TVs). In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the NR111D PWM controller chip itself may be faulty (8). It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuit.
If the PHILIPS 32PFL3208T has no image, there is sound and the channels are switched, there is a possibility of a malfunction in the circuit of the panel backlight LEDs code 196 996590004721, or their power converter - LED driver. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
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.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes.
In cases of attempts to repair the motherboard 715G5713-M0E-000-005X 996590004721, 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.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of electronic equipment repair.

Key Features of PHILIPS 32PFL3208T:
Installed matrix (LED panel) TPT315B5-TU4A code 196 p / n: 996590004721.
To power the backlight LEDs, a converter is used, combined with the power supply, it is controlled by the PF7900S, PF7700A PWM controller. As power elements of the LED driver, keys of the AOD4126 type are used.
The required supply voltages for all nodes of the PHILIPS 32PFL3208T TV are generated by the 715G5793-P01-000-002M power supply module or its analogs using PF6200 (PWM flyback), NR111D (PWM Step-down) microcircuits and power switches of the STF10N65K3 type.
