PHILIPS 32PFL7582D
General recommendations for repairing TV LCD
It is recommended that you start the diagnostics of a malfunction of the PHILIPS 32PFL7582D / 10 TV, as well as all other electronic devices, with an external examination of both external and internal elements and modules. It often happens that some damage to elements or connections helps determine the direction of the troubleshooting. In most cases, the repairman can guess the causes of the defect and possible consequences from the characteristic signs of typical TV defects, for example, ring cracks formed in the soldering of the element leads, swollen rectifier filter capacitors, charred resistors and other circuit elements.
Power Module Repair
If the 32PFL7582D / 10 TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power supply module. In some cases, only the regulator or power converter of the control processor may be faulty, which is typical for some PHILIPS models. When diagnosing and repairing the power supply, first of all, replace the swollen capacitors of the filter 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.
As a rule, the keys of flyback converters, which use an N-Fet field effect transistor on a separate radiator, or integrated with a PWM controller in a single chip, are reliable enough and rarely fail for no reason. The reasons for the breakdown of the key should be sought by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
Diagnostics of power modules with a Power Factor Corrector (CMC) is somewhat more complicated and requires a more detailed approach.
Inverter Repair
In cases where the PHILIPS 32PFL7582D / 10 TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of an inverter (converter for powering the backlight) malfunction. When you turn on the TV, the image may appear briefly and immediately disappear. It must be borne in mind that with such manifestations, the lamps themselves also fail, the malfunction of which can be detected by replacement, by connecting to the connectors for diagnostics that are known to be serviceable and suitable in power.
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.
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
Repair or diagnostics of the BJD 32 / 37L EU motherboard should begin by checking the stabilizers or power converters of its microcircuits. If necessary, you should update the software (software).
Owners of the 32PFL7582D / 10 TV are recommended for repairing contact only qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

The appearance of the power supply
Main features of the PHILIPS 32PFL7582D device:
Installed matrix (LCD panel) LC320W01 (SL) (06) code 046.
To power the backlight, an inverter KLS-EE32CI-M is used, it is controlled by the BD9766FV PWM controller (28), OZ9981GN (16) .. As the power elements of the inverter, keys like RSS100N03 (8) are used.
The necessary supply voltages for all nodes of the PHILIPS 32PFL7582D TV are generated by the power supply module 3104_313_60926, or its analogs using microcircuits MC34067P (PWM), AVS1ACP08 and power switches of the STP15NK50ZFP type.
MainBoard - the main board (motherboard) is a module 3104_313_60735, using chips PNX8550, K4D551638H-LC50, PNX3000HL, ISP1561BM, K96561 and others.
