General repair guidelines for TV LCD LED
Repair of all electronic devices, including the PHILIPS 22PFL4208T / 60 TV, it is advisable to start with an external examination of its external and internal elements. Many visible changes in the state of the elements make it possible to determine the further direction of troubleshooting and localization of the defect. 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.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, it does not make any sounds or any signs of operability when it is turned on, there is a certain chance that the 715G5804-P01-W22-001M 996590005303 power supply module is faulty and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of processor power, which is typical for certain PHILIPS models. 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 cut off, then it is necessary to check the diodes of the rectifier bridge and the key transistor of the converter for a breakdown of the PN junctions, 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 PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
If, when you turn on the TV, the image appears and immediately disappears, or is missing initially when you turn on, but the sound has other functions that work, there is a high probability of a malfunction of the LED driver (power converter for panel backlight LEDs code 200 996590005301). In such cases, the common power module is also subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the LED driver should be checked.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
It should be remembered that it is not possible to determine the open circuit in the LED lines without disassembling the panels with a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
On the motherboard 715G5713-M0F-000-005X 996590005315, 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).
If you suspect a malfunction of the TDSY-G230D tuner, first of all, you need to make sure that there is a varicap supply voltage (30-33V) at the corresponding output of the tuner, as well as other voltage supplying it.
Owners and users of the PHILIPS 22PFL4208T TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

Installed matrix (LED panel) TPM215HW01-HGJL02 code 200 p / n: 996590005301.
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 22PFL4208T television are generated by the 715G5804-P01-W22-001M power supply module or its analogs using PF6200 microcircuits and power switches of the STF6N65K3 type.
