General repair guidelines for TV LCD LED
Repair of TVs, as well as other devices, it is advisable to start with an external examination. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
If the ERISSON 24LES66 does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a power module malfunction. In some cases, only the processor power regulator may be faulty. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip can also cause a breakdown of the power switch of the converter.
If the ERISSON 24LES66 TV does not have an image, but there is sound, a malfunction in the backlight circuits of the HM236WU3-100 LED panel is likely.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the lines and connectors.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source.
The motherboard 5800-A8M280-OP10 VER10.00 must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up constantly. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary.
Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the SPI Flash elements: Q32B-104HIP; . BGA chip malfunctions are usually easy to detect by warming up.
If there is no reception of television channels, but the TV is working properly from external devices, first of all you need to check the power supply of the tuner ET-9Z2E-CF106H and update the software.
For 24LES66 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!

5800-A8M280-OP10 can be used in TVs:
ERISSON 24LES66 (Panel HM236WU3-100), ERISSON 19LES66 (Panel E185SG01 REV:01), HYUNDAI H-LED29V17 (Panel V290BJ1-PE1 VRev.C2), SUPRA STV-LC24660FL (Panel HM236WU3-100).
The appearance of the power supply
Installed matrix (LED-panel) HM236WU3-100.
To power the backlight LEDs, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the TV ERISSON 24LES66 are formed by the power supply module 168P-P19EQB-HCW-1, or its analogs.MainBoard - the main board (motherboard) is a 5800-A8M280-OP10 module, using SPI Flash chips: Q32B-104HIP; and others.
The ET-9Z2E-CF106H tuner provides television reception and channel tuning.
TV ERISSON 24LES66 with LCD HM236WU3-100, diagonal size 24 "(61 cm) 16: 9 format. The required brightness of the screen 300 cd / m² is provided by LED backlight LED. Contrast, as the ratio of maximum brightness to minimum, is 1000: 1. The LED panel of this TV has an end LED backlight - Edge LED.The TV design and technical features include viewing programs and movies in high quality HD at a resolution of 1920x1080 pixels in a graphic resolution of 1080p (Full HD) standard.

Attention! The HM236WU3-100 panel of an ERISSON 24LES66 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.
