General repair guidelines for TV LCD LED
Repair of the HYUNDAI H-LED22V16 TV should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. Often, by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain probability that the power module is defective and needs repair. Sometimes with similar manifestations a problem may occur only in the absence of processor power, which is typical for certain HYUNDAI models. 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.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
Sometimes the HYUNDAI H-LED22V16 TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the LED backlight converter M215HW01 V.B, or an open circuit in the LED circuit is possible. In such cases, first of all, it is necessary to verify the serviceability of all the electrolytic capacitors of the filter by supplying the LED driver itself, including in the power supply unit (power supply unit).
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.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
If the motherboard CV1811-A is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its MST6E181VS-LF-Z1 chips and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
Before replacing the F03WT-3DDR-E 1112J1697 tuner, if there is no tuning for the channels, you must first check the power supply voltage at its terminals, including the power supply of varicaps (30-33V).
For owners of the H-LED22V16 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!
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.

Main features of the HYUNDAI H-LED22V16 device:
Installed matrix (LED panel) M215HW01 V.B.
To power the backlight LEDs, the LDA13-63V200F LED driver is used, controlled by the BIT3251 PWM controller (8). As power elements of the LED driver, keys of the 12N10L type are used.
The required supply voltage for all nodes of the HYUNDAI H-LED22V16 TV provides a switching power supply.
MainBoard - the main board (motherboard) is a CV1811-A module, using MST6E181VS-LF-Z1 chips and others.
The F03WT-3DDR-E 1112J1697 tuner provides TV reception and channel tuning.
