General repair guidelines for TV LCD LED
Any repair usually begins with an external inspection. 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. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
If the 24LES61 TV does not turn on, does not make any sounds when turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power module. In some cases, there may be a malfunction only in standby power. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
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 the ERISSON 24LES61 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the 1080p Full HD, 1920x1080 panel, or their power converter - LED drivers. Sometimes, when turned on, the image appears and immediately disappears. 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.
When trying to detect a break in the LED lines, it should be taken into account that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
Diagnostics and repair of the 5800-A8M350-0010 V1.8 motherboard usually begins with a test of the performance of the stabilizers and power converters of the module chips. In some cases, a software update is required.
Board repair and replacement of CPU chips: MST740KE-LF; SPI Flash: 25X80; EEPROM: 24C32; 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.
If there is no reception of television channels, but the TV is working properly from external devices, first of all, check the voltage of the HFT-8F6 / 125CW tuner and update the software.
For 24LES61 TV owners, we recommend that you contact qualified professionals with work experience for repairs! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

The required supply voltage for all nodes of the TV ERISSON 24LES61 provides a switching power supply.
MainBoard - the main board (motherboard) is a 5800-A8M350-0010 module, using CPU chips: MST740KE-LF; SPI Flash: 25X80; EEPROM: 24C32; and others.
The HFT-8F6 / 125CW tuner provides TV reception and channel tuning.
ERISSON 24LES61 TV with a 1080p LCD display, 24 "(61 cm) diagonal size in 16: 9 format. The LED-panel of this TV has LED end lighting - Edge LED. The design and technical capabilities of the TV include watching programs and movies in high HD quality at a resolution of 1920x1080 pixels in a graphic decomposition according to the standard 1080p (Full HD). The input high-frequency or video signal can be processed in analog systems PAL, SECAM, NTSC. Graphic processing and digital signal generation occurs in the standards 480i, 480p, 576i, 576p,720p, 1080i, 1080p. Stereo sound is realized by two built-in speakers. NICAM STEREO audio processing system is used.
The external interface (communication with other devices) is supported by standard input and output connectors: antenna input (RF), AV, audio x3, component, SCART, RGB, VGA, HDMI. An output for connecting headphones is provided. To connect a computer or laptop to this TV model, a VGA (D-Sub 15) connector is used on the TV case, this interface supports resolutions: 640x480, 800x600, 1024x768, 1280x1024.

Attention! The 1080p Full HD, 1920x1080 panel of an ERISSON 24LES61 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.
