General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular ERISSON 24LES68, it is advisable to start with a careful external examination of internal and external 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. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
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. When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and the electrolytic capacitors of the filters of the converter secondary rectifiers. In the event of a fuse breaking, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch (s) of the converter.
Power switches in switching 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 cause may be a malfunction of the PWM controller chip, which can only be checked by replacing it with a new or obviously working one.
If, when you turn on the TV, the image appears and immediately disappears, or is missing initially when you turn on, but the sound has other functions that work, there is a high probability of a malfunction of the LED driver (power converter for the backlight LEDs of the panel 720p HD, 1366x768). In such cases, the general power module is also subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the LED driver should be checked.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
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.
Repair or diagnostics of the 5800-A5M63E-OP10 motherboard should begin by checking the stabilizers or power converters of its microcircuits. If necessary, you should update the software (software).
When repairing an MB board, you need to check its components CPU MSD6306PUN, Flash 25Q32GD. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating.
Attention! For users and owners of 24LES68 TVs who do not have the appropriate qualifications, knowledge and experience, we categorically do not recommend attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

Attention! The 720p HD, 1366x768 panel of an ERISSON 24LES68 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.
