General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular PHILIPS 32HFL3007D / 10, it is advisable to start with a careful external examination of internal and external 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. In some cases, faulty elements can be seen with the naked eye, for example, charred resistors or swollen metal-ceramic capacitors, or electrolytic in rectifier filters. Ring cracks formed in the soldered terminals of transformers or heating elements of the circuit are also frequent sources of many malfunctions with a variety of external manifestations.
Sometimes the PHILIPS 32HFL3007D TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is the failure of the 715G5508-P02-000-002M common power supply module. If it is working properly, you need to check the processor batteries on the SSB (Main Board). When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. When it is broken, the power elements of the transistors 10N65K3, AO TF409 and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
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 54241 (8) may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
If the PHILIPS 32HFL3007D TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the TPT315B5-J3L01 RevC1F code 175 is likely. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for an overstated ESR.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and connectors.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source.
Repair of the motherboard 715G5155-M1B-002-005K 705TQCPL087 should begin with the diagnosis and verification of all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM.
Before changing the tuner ENV57U09D5F, if it is not possible to tune to television channels, make sure that there are supply voltages, including varicap power (30-33V), which must be measured on the corresponding tuner pins.
Attention to users! Do-it-yourself repair of the PHILIPS 32HFL3007D TV without the appropriate qualifications and experience can lead to its complete non-repairability!
