ERISSON 23LEN60
General repair guidelines for TV LCD LED
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should examine all the internal components of the ERISSON 23LEN60 TV, as well as the external elements of the housing. 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.
Malfunctions of the FLY-PWCB2604 power supply module can be expressed in different ways, for example, ERISSON 23LEN60 does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM controller chip are subject to verification, which it is desirable to verify by replacement.
If the ERISSON 23LEN60 does not have an image, but there is sound, the backlight LEDs of the LM230WF5 panel or their power converter may malfunction. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
To check the health of the LEDs, as well as contact connections in the ruler circuit, it is necessary to disassemble the panel.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
The motherboard T.MS18VG.62B 11505 must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up continuously. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary.
In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - SPI FLASH: Anxson 25Q32, Audio: 1517P with new or obviously good ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
If there is no reception of television channels, but the TV works properly from external devices, first of all it is necessary to check the voltage of the varicaps of the tuner CDT-35P512-3F, which is usually within 30-33V, as well as other supply voltages at the terminals of the tuner.
Attention to the owners! Attempts at self-repair of the ERISSON 23LEN60 TV are not recommended by the manufacturer and can lead to serious negative consequences!

Attention! The LM230WF5 panel of the ERISSON 23LEN60 LED TV is an expensive and unreliable element.
Avoid any impact on the glass and pressure on the surface of the screen to avoid damage to the LED panel!
