ERISSON 16LEE01
General repair guidelines for TV LCD LED
ERISSON 16LEE01, like other televisions, it is advisable to start repairing from inspection of external and internal elements and modules. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the outputs of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external signs of certain malfunctions.
If the TV does not turn on, no control lights are on or blinking, there are no sounds when you turn on, and there is not the slightest sign of operability - the most likely malfunction is in the power module. When diagnosing and repairing the power supply, first of all, replace the swollen capacitors of the filter of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
A breakdown of the power switch of the pulse converter is often triggered by other elements, for example, in the stabilization or control circuits of this switch, as well as by the damper elements in its drain and TPI winding.
Sometimes the ERISSON 16LEE01 TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the converter for the backlight LEDs of the 720p HD, 1366x768 panel, or a break in the LED circuit is possible. In such cases, first of all, it is necessary to verify the operability of the electrolytic capacitors of the filter by supplying the LED driver itself, including the PSU.
The lack of backlight often occurs due to an open circuit in the LED circuit. There is a need for disassembling the panel and checking the LEDs themselves, as well as the same contact 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.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - CPU: MST6E181VS-LF-Z1; SPI Flash: 25L3206E; to new or obviously serviceable. In cases where BGA technologies are used, defects are usually localized by the heating method.
If you suspect a malfunction of the CDT-3SP5I2-36 tuner, first of all, you need to verify the correctness of the software, as well as the presence of the necessary voltage levels at the corresponding terminals of the tuner.
Attention to the owners! Attempts to self-repair the ERISSON 16LEE01 TV are not recommended by the manufacturer and can lead to serious negative consequences!

Attention! The 720p HD, 1366x768 panel of an ERISSON 16LEE01 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.
