General repair guidelines for TV LCD LED
TV PHILIPS 32PFL3188T / 60, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. In some cases, visible external damage to the elements can indicate the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of electronic circuit nodes. 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.
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, it does not make any sounds or any signs of operability when it is turned on, there is a certain chance that the 715G6079-C0D-000-004K mono power 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. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse is broken, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
Power switches in pulsed power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The reason may be a malfunction of the PWM regulator chip LD7752B, SP6018S8RGB, which can only be checked by replacing it with a new or obviously working one.
If the PHILIPS 32PFL3188T does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the TPT315B5-EUJFFA REV panel: S1D code 007 996590007793, or their power converter is an LED driver. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
A malfunction in the backlight circuits often occurs due to an open in the power circuit of the LED lines. It requires disassembling the panel and checking the LEDs themselves, the rations of their terminals, as well as the reliability of the connections in the connectors and rations of the terminals.
When trying to detect a break in the LED lines, it should be taken into account that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
Diagnostics and repair of the motherboard 715G6079-C0D-000-004K 996590007797 705TXDSC32901T is carried out by checking the operability of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Verification or replacement of elements NT72567, AON4421, RT7234GSP, SY8009BABC requires the necessary training and professional skills in repairing modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
Owners and users of the PHILIPS 32PFL3188T TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!
