General recommendations for repairing TV LCD
It is advisable to start any repair and diagnostics of the PHILIPS 26PFL5322S / 60 TV, as well as other devices, with a careful external examination of internal and external elements, including case parts, a display, buttons and cables. Many visible changes make it possible to determine the future direction of troubleshooting and localization of the defect. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
Power Module Repair
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, does not make any sounds or any signs of operability when it is turned on, there is a certain chance that the PLCD190P3 24431 power supply module is defective 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 and happens much less often. 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 cause should be sought in the power semiconductor elements of the pulsed flyback converter of the main power supply unit. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch of the converter inv BA7228 D454 pl BA721U D413 pl, which can be installed separately on the radiator, or integrated with a PWM controller.
If a breakdown of the power switch of the flyback converter of the power supply unit is detected, it should be remembered that 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 AS324M-E1 (14n) pl. which can be checked only by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If an active Power Factor Corrector (PFC) is used in the power module circuitry, it is sometimes more difficult to troubleshoot. Knowledge, experience, intuition and skills in such cases have a great advantage for a successful repair.
Inverter Repair
If the PHILIPS 26PFL5322S / 60 does not have an image, but there is sound and the TV is controlled from the remote control, a malfunction in the display backlight nodes is likely. The lamps or the power converter - inverter may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the inverter, and check the LCD lamps by connecting external and obviously serviceable for diagnosis to the connectors.
Repairing the VIT70038.50 Rev3 inverter is difficult because in case of any malfunction or emergency, even if the lamps wear unevenly, protection is triggered, which turns it off for fire safety. Diagnostics become impossible and protection needs to be disabled.
It should be remembered that in such cases there is a risk of failure of the power elements of the inverter and to take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
Repair Main Board
In cases of attempts to repair the motherboard SSB 313926853382, it is necessary to check the operability of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). In cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - TDA9886T, TDA8932T, Sil8025CTU, tuner UV1318S / A, which may require replacement with new ones.
Attention to users! Do-it-yourself repair of the PHILIPS 26PFL5322S / 60 TV without the appropriate qualifications and experience can lead to its complete non-repairability!
