General recommendations for repairing TV LCD
Possible malfunctions
- The PHILIPS 42PES0001D TV does not turn on at all. The control lights do not light or flash. On the remote control and the buttons on the control panel does not respond.
In such cases, the fault should be sought first in the PLCD260PS07 power supply module. It is necessary to measure its output voltages and, if they are absent, to check the short circuit probability in the converters power switches and rectifier diodes.
In case of avalanche and thermal breakdowns of diodes in the secondary circuits, the converter can operate in emergency short circuit mode, and in case of short circuit in the power elements of the primary circuit, a mains fuse or a current sensor at the source of the key usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. The PWM chip can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
These manifestations can be triggered by the power module, or by inverter defects, as well as by the distortion of the currents in the lamps due to their uneven wear. If all the electrolytic capacitors of the filter according to the inverter power supply are serviceable, you should make sure that the lamps are in good working condition, then you need to check the converter keys and the secondary windings of the transformers.
Sometimes, for diagnostic purposes, inverter protection must be disabled. In such cases, special care must be taken during work, and the protection circuits should be restored immediately after the repair is completed.
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the 28579715015904 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software).
In the absence of tuning to the channels of terrestrial or cable television, you should make sure that the software is correct, as well as in accordance with the ratings of the supply voltages on the terminals of the tuner TD1716F / PHXP-3 3139 147 27501. It is also necessary to check the presence of tuner data exchange pulses with an oscilloscope with processor on the I2C bus.
We recommend the owners of the 42PES0001D TV for repair only to qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!
Main features of the PHILIPS 42PES0001D device:Installed matrix (LCD panel) T420HW03 v.0 p / n: 9322 265 50668.
To power the backlight, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the PHILIPS 42PES0001D TV are generated by the PLCD260PS07 power supply module or its analogs.
