ERISSON 22LEE01
General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular ERISSON 22LEE01, it is advisable to start with a careful external examination of internal and external elements. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. 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.
In cases when the ERISSON 22LEE01 TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink and there are no sounds and no signs of operability at all, the power module is most likely faulty or there is no processor power on motherboard (a typical defect of some ERISSON TV 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 breaks, 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.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If the ERISSON 22LEE01 does not have an image but there is sound, the backlight LEDs of the CLAA215FA04 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.
If the motherboard T.MS6M181.7A is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
Board repair and replacement of CPU chips: MST6E181VS-LF-Z1; SPI Flash: MX25L3205; are made in the presence of the necessary equipment and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
In cases where there is no tuning to the local television channels, you should make sure that there are supply voltages at the terminals of the AFT7 / W130G tuner.
Attention to the owners! Attempts to repair the TV ERISSON 22LEE01 on its own are not recommended by the manufacturer and can lead to serious negative consequences!
FIRMWARE FOR SPI FLASH -----------> ERISSON 22LEE01, Main: T.MS6M181.7A, Panel: CLAA215FA04
The appearance of MainBoard T.MS6M181.7A is shown in the figure below:Repair of the motherboard T.MS6M181.7A, which uses the multifunctional processor MST6M181VS combined with a scaler, is advisable to start by checking the power supply of the standby mode, which is implemented using a separate linear stabilizer 3.3V. Further, in the operating mode, it is necessary to check the operability of linear stabilizers or voltage converters necessary to provide power to the processor nodes: 1.2V, 2.5V, 3.3V. A voltage of 2.5V is required to power the DDR W9425G6JH memory. If there is a backlight and no image, the power of the LCD panel 5V or 12V, depending on the type of panel used, it is advisable to measure directly on the LVDS connector. If the TV does not exit Stand-by, does not respond to the remote control and control buttons, update the SPI FLASH software.

Attention! The CLAA215FA04 panel of an ERISSON 22LEE01 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!
It is also unsafe to get liquid on the screen. Sometimes one drop is enough if it flows down the glass onto the cables so that the TV becomes unrepairable.
