General repair guidelines for TV LCD LED
Repair of the PHILIPS 22PFL3108H / 60 TV should begin with a careful external examination of all its components and modules. 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. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the soldered terminals of transformers or heating elements are detected, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
Faults in the 715G6297-P01-000 power supply module can be expressed in different ways, for example, PHILIPS 22PFL3108H does not turn on at all and the control lamps on its front panel do not light up and do not blink, and there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and the electrolytic capacitors of the filters of the converter secondary rectifiers. In the event of a fuse breaking, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch (s) of the converter.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, PWM controller PF7001S. D55, which can only be checked by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
Sometimes the PHILIPS 22PFL3108H TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the TPM215HW01-HGJ panel backlight LED converter, or a break in the LED circuit is possible. In such cases, first of all, it is necessary to verify the serviceability of all the electrolytic capacitors of the filter by supplying the LED driver itself, including in the power supply unit (power supply unit).
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.
When trying to detect a break in the LED lines, it should be taken into account that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
In cases of attempts to repair the MAIN P / N 996590008044 715G6092-MOD-000-004N motherboard, 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.
Remember! Attempts to self-repair by users of the PHILIPS 22PFL3108H TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

The appearance of the power supply
Main features of the PHILIPS 22PFL3108H device:
The matrix (LED panel) TPM215HW01-HGJ is installed.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the PF7001S PWM controller. As the power elements of the LED driver, keys of the MTD55N10Q8 type are used.
The necessary supply voltages for all nodes of the PHILIPS 22PFL3108H TV are generated by the 715G6297-P01-000-001E power module, or its analogs using PF6200 microcircuits and TK6A65D type power switches.
MainBoard - the main board (motherboard) is a module 715G6092-M0D-000-004N.
