General repair guidelines for TV LCD LED
Repair of the HYUNDAI H-LED24V14 TV should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. A visible physical change in some components can sometimes suggest a further troubleshooting direction. In some cases, faulty elements can be seen with the naked eye, for example, charred resistors or swollen metal-ceramic capacitors, or electrolytic in rectifier filters. Ring cracks formed in the soldered terminals of transformers or heating elements of the circuit are also frequent sources of many malfunctions with a variety of external manifestations.
In the case when the H-LED24V14 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink bulbs and does not show any signs of operability, the AY050D-2SF03 power supply module is probably faulty in this case. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
If the power keys of the pulse converter are not equal, you should pay attention to other elements in their bundling, which may be the result or cause of their breakdown.
If the HYUNDAI H-LED24V14 TV does not have an image, but there is sound, a malfunction in the backlight circuits of the LED panel ECG236MB-LC1 (RP) 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 rulers and connectors.
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.
In cases of attempts to repair the motherboard JUG7.820.1287, it is necessary to check the operability of the linear stabilizers and power converters of its microcircuits and, if possible, update the software (software). BGA chips can sometimes be diagnosed with local heating.
When repairing an MB board, you need to check its components SPI Flash: EN25Q32B; . Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating.
The malfunction of the R620D RAFAEL MICRO tuner is established after checking the software and all supply voltages at its terminals.
For owners of the H-LED24V14 TV, we recommend that you contact qualified professionals with experience to repair! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

Attention! The panel of the HYUNDAI H-LED24V14 LED TV ECG236MB-LC1 (RP) 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.
