General repair guidelines for TV LCD LED
It is advisable to start repairing the ERISSON 32LES62 TV with a careful external examination of both internal and external elements. Visible damage to the elements can sometimes indicate the direction of the search for the defect even before the necessary measurements. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the solders of the terminals of transformers or heating elements are detected, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
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, does not make any sounds or any signs of operability when turned on, there is a certain probability that the power module is defective and needs repair. Sometimes with similar manifestations a problem may occur only in the absence of processor power, which is typical for certain ERISSON models. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in such a state of breakdown.
The reasons for the breakdown of the power switch in pulsed power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or broken resistors in its bundle.
If the ERISSON 32LES62 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction in the LED backlight circuit of the 720p panel, or their power converter - 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.
A break in the line of LEDs connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
In cases of attempts to repair the motherboard 5800-A8M260-0020, it is necessary to check the operability of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
When repairing an MB board, you need to check its components Cpu: MST6E181VS-LF-Z1, Spi Flash: 25L3206 Ram - M13S2561616A, Audio: PS331. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating.
If the TV works normally from external devices, but does not tune into television channels, the HFT2-8F / 115CW tuner may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals.
Once again, remind users! Attempts to self-repair a TV ERISSON 32LES62 without the appropriate qualifications and experience can lead to its complete non-repairability!
