General repair guidelines for TV LCD LED
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should examine all the internal components of the PHILIPS 22PFL4008T / 60 TV, as well as the external elements of the case. Often, based on certain external signs, it may be possible to draw certain conclusions about the reasons for the failure of certain elements of the circuit even before the necessary measurements are made, which will determine the further algorithm for troubleshooting and localizing the defect. In some cases, faulty elements can be seen with the naked eye, for example, charred resistors or swollen metal-ceramic capacitors, or electrolytic in rectifier filters. Ring cracks formed in the soldered terminals of transformers or heating elements of the circuit are also frequent sources of many malfunctions with a variety of external manifestations.
If the PHILIPS 22PFL4008T does not turn on, no control lights on the front panel are lit or blinking, therefore, there is a very high probability of a 715G5804-P01-W20-001M power supply module malfunctioning. In some cases, only the processor power regulator may be faulty. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in such a state of breakdown.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
If there is no image when you turn on the PHILIPS 22PFL4008T, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the circuit of the panel backlight LEDs code 200, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
A malfunction in the backlight circuits often occurs due to a break in the power supply lines of the LED lines. It requires disassembling the panel and checking the LEDs themselves, the rations of their terminals, as well as the reliability of the connections in the connectors and rations of the terminals.
An open in the LED lines connected in series cannot be detected using a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
On the motherboard 715G5675-M01-000-005K 705TQDSCC0701T, in case of a malfunction, you should first check the operation of all the stabilizers or power converters of the microcircuits and, if necessary, update the software (software).
Before replacing the TDSY-G230D tuner, if there is no tuning for the channels, first you need to check the supply voltage at its terminals, including the varicap supply (30-33V).
Attention to users! Do-it-yourself repair of the PHILIPS 22PFL4008T TV without the appropriate qualifications and experience can lead to its complete non-repairability!

Main features of the PHILIPS 22PFL4008T device:
Installed matrix (LED panel) TPM215HW01-HGJL02 code 200.
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 type AO4486 are used.
The necessary supply voltages for all nodes of the PHILIPS 22PFL4008T TV are generated by the 715G5804-P01-W20-001M power supply module or its analogs using PF6200 microcircuits and power switches of the STF6N65K3 type.
MainBoard - the main board (motherboard) is a module 715G5675-M01-000-005K, using microchips MTK5580CPOI, TC58NVG1S3ETAI0, CAT24C128WI, STA381BWTR and others.
