General repair guidelines for TV LCD LED
Possible manifestations of defects
- The HYUNDAI H-LED22V6 TV does not turn on and does not show any signs of turning on. There is no reaction to the control buttons and the remote control.
Most often, with such manifestations, the Adapter power module is faulty.
This model of TV is equipped with an external power adapter adapter type 12V, which the owner can purchase independently, and repairing it may not always be advisable, however, sometimes it makes sense to open it and eliminate simple typical defects typical of IPS. It is necessary to measure the secondary output voltage, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the elements of the primary circuit, the mains fuse usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power switch may be PWM (PWM). It is checked only by replacement with a known good one.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. The reason can be both in the power of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
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.
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the CV182L-C motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the elements SPI: W25Q32FV (U5), Sound: YD1517. BGA chip malfunctions are usually easy to detect by warming up.
If you suspect a malfunction of the CDT-3SP5I2-37 tuner, first of all, you need to verify the correctness of the software, as well as the presence of the necessary voltage levels and pulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.
It should be remembered! Attempts to independently repair the HYUNDAI H-LED22V6 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!
FIRMWARE FOR SPI FLASH -----------> HYUNDAI H-LED22V6, Main: CV182L-C 2AJ1109A H, Panel: M215HW03 V.1
The appearance of the MainBoard CV182L-C is shown in the figure below:The CV182L-C motherboard uses the MST6M182VG processor, combined with a scaler and installed using the BGA technology.
It is advisable to start this type of MainBoard repair by checking the voltage converters and linear stabilizers necessary to provide power to the processor nodes: 1.2V, 2.5V, 3.3V. Check the power supply of the 5V or 12V LCD panel, depending on the type of panel used, it is advisable directly on the LVDS connector. If, in the presence of the necessary supply voltage, the TV does not exit Stand-by mode, does not respond to the remote control and control buttons, the SPI Flash software should be updated.
CV182L-C can be used in TVs:
HYUNDAI H-LED24V6 (Panel M240HW01), HYUNDAI H-LED19V6 (Panel M185B3-LC1 Rev.C1), HYUNDAI H-LED19V16 (Panel LM185WH2), HYUNDAI H-LED15V6 (Panel LP156WD1 (TL)(A1)), HYUNDAI H-LED22V6 (Panel M215HW03 V.1).
Main features of the HYUNDAI H-LED22V6 device:
Installed matrix (LED-panel) M215HW03 V.1.
The LED driver HG-LED58-1K7 is used to power the backlight LEDs, it is controlled by the HQ9002 PWM controller. As power elements of the LED driver, keys of the B0210D type are used.
To power all internal nodes of the HYUNDAI H-LED22V6 TV, an external adapter 12V type is used.
MainBoard - the main board (motherboard) is a CV182L-C module using SPI chips: W25Q32FV (U5), Sound: YD1517 and others.
The tuner CDT-3SP5I2-37 provides the reception of television programs and tuning to channels.
