General repair guidelines for TV LCD LED
HYUNDAI H-LED15V6, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. Many visible changes in the state of the elements make it possible to determine the further direction of troubleshooting and localization of the defect. 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.
In the absence of any signs of operability, when the HYUNDAI H-LED15V6 does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the TV power module. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. 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 pulsed 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 LP156WD1 15.6 HD +). 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.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
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.
Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing CPU elements: MST6E181VS-LS-Z1, Flash: 25Q32B, RAM: W9425G6JH-4, Sound: TDA1517P requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
The malfunction of the F03WT-3DDR-E tuner is established after checking the software and all the supply voltages at its outputs, including the varicap supply voltage (30-33V).
Remember! Attempts to self-repair by users of the HYUNDAI H-LED15V6 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

The appearance of the MainBoard CV181L-A is shown in the figure below:CV181L-A
As part of the CV181L-A motherboard, a multifunctional processor MST6M181VS is used, combined with a scaler (video controller-scaler). It is advisable to start the MainBoard repair by checking the power supply of the Stand-by mode, which is implemented using a separate 3.3V linear stabilizer. In the operating mode, it is necessary to check the operability of linear stabilizers or voltage converters necessary to provide power to the processor nodes: 1.2V, 2.5V, 3.3V. A voltage of 2.5 V is required to power the DDR W9425G6JH-4 random access memory. If there is no image, but the display backlight is working properly, it is advisable to measure the power of the 5V or 12V LCD panel, depending on the type of panel used, directly on the LVDS connector. If the TV does not exit Stand-by mode, does not respond to the remote control and control buttons, you should check the 3.3V power at pin 8 of the SPI FLASH chip, it may be necessary to update its software.
CV181L-A can be used in TVs:
FUSION FLTV-19T9D (Panel TB190B1Z1), FUSION FLTV-22T9D (Panel HM215WU1-500), HYUNDAI H-LED22V16 (Panel M215HW01 V.B), HYUNDAI H-LED15V6 (Panel LP156WD1 (TL)(A1)), SUPRA STV-LC2277FLD (Panel HK215LEDM-BH 1H), SUPRA STV-LC2425WL (Panel M240HW02 V.1), SUPRA STV-LC1677WL (Panel 720p HD 1366x768).
