General repair guidelines for TV LCD LED
Television ELENBERG LE236N59W, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. 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 leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
If the ELENBERG LE236N59W does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a malfunction of the PCB power supply module - MP113-W. In some cases, only the processor power regulator may be faulty. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is cut off in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
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 for no reason 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, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but the sound is there and other functions work, there is a high probability of a malfunction of the LED driver (power converter for the backlight LEDs of the HM236WU-100 panel). 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.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes.
If the CV59L-C motherboard is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, as well as, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
Board repair and replacement of Cpu: TSUMV59XE-Z1 chips, Spi Flash: 25Q32, Audio: YD1517 are made with the necessary equipment, and the corresponding hardware base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
Attention! Users and owners of LE236N59W TVs who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.
FIRMWARE FOR SPI FLASH -----------> ELENBERG LE236N59W, Main: CV59L-C, Panel: HM236WU-100
The appearance of the MainBoard CV59L-C is shown in the figure below:MainBoard CV59L-C uses a multifunctional microprocessor type TSUMV59 with an integrated scaler and an external SPI Flash ROM type 25Q32 (4Mb).
It is advisable to begin repairing the motherboard by checking the + 5V voltage converters and the + 1.2V processor core power, as well as the + 3.3V linear voltage regulators and the 1.8V DDRAM processor internal RAM.
In the case of a working display backlight and the absence of an image, it is necessary to check the panel power (depending on the type, + 5V or + 12V), which can be measured directly on the LVDS connector. If, in the presence of all the supply voltages, the TV does not enter the operating mode, does not respond to the Remote Control and the control buttons, the SPI Flash software should be updated.
CV59L-C can be used in TVs:
DNS E16A20 (Panel TL156WH4 (TL)(N2)), DNS E19A11 (Panel CX185LEDM (M185BGE-P02)), ELENBERG LE236N59W (Panel HM236WU-100), TELEFUNKEN TF-LED19S2 (Panel A185CD1B1E-2-A).
Main features of the ELENBERG LE236N59W device:
Installed matrix (LED panel) HM236WU-100.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a BIT3251 PWM controller.
The necessary supply voltages for all nodes of the ELENBERG LE236N59W TV are generated by the MP113-W power module or its analogs using OB2273 microcircuits (PWM SOT23-6).
MainBoard - the main board (motherboard) is a CV59L-C module, using Cpu chips: TSUMV59XE-Z1, Spi Flash: 25Q32, Audio: YD1517 and others.
ELENBERG LE236N59W TV with an LCD display, diagonal size 24 "(61 cm) in 16: 9 format. The LED-panel of this TV is equipped with LED backlighting - Edge LED. The design and technical capabilities of the TV include watching programs and movies in high quality HD at a resolution of 1920x1080 pixels in 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, 720 p, 1080i. Supported media file formats: MP3, MPEG4, JPEG. 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), HDMI, USB. 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, 1360x768.
Overall dimensions: With stand 515x361x161 mm, Without stand 515x357x62 mm.
Attention! The screen of the LED-TV ELENBERG LE236N59W is its most expensive and most 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.
