General recommendations for repairing TV LCD
It is advisable to start repairing the PHILIPS 26PFL3606H / 12 TV with a careful external examination of all its components and modules. Also subject to inspection are body elements, functional control buttons, screen, cords and connectors. In some cases, visible external damage to the elements can suggest directions for troubleshooting and localizing the defect before starting the necessary measurements at the control points of the nodes of electronic circuits. 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
Malfunctions of the power module can be expressed in different ways, for example, PHILIPS 26PFL3606H / 12 does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module - rectifier diodes or power switch.
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 for no reason, which should be sought by checking other elements of the primary circuit - electrolytic capacitors, PWM controller LC260WXE SB B1, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
It is somewhat more difficult to find faults in the converter of the power module with an active KKM (power factor corrector).
Inverter Repair
If there is no image when you turn on the PHILIPS 26PFL3606H / 12, or it appears for a second and disappears completely, but there is sound, most likely either the backlight lamps or their power converter (inverter) are faulty. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
The operation of the power circuits of the inverter and the backlight in the normal mode are controlled by special protection, which is organized for fire safety, for example, to disconnect during short circuits or breaks in high-voltage connections or when the lamps are depressurized. This protection makes it difficult to diagnose and repair the inverter.
In such cases, special care should be taken during diagnostics, and after completion of all repair work, it is necessary to restore the circuit and the inverter protection for further safe operation of the TV.
Attention to users! Do-it-yourself repair of the PHILIPS 26PFL3606H / 12 TV without the appropriate qualifications and experience can lead to its complete non-repairability!
