General repair guidelines for TV LCD LED
Possible malfunctions
- The HYUNDAI H-LEDVD22V10 TV does not turn on and does not show any signs of operability at all. There is no reaction to the remote control and control buttons from the front panel.
With such manifestations, a malfunction is most likely to be detected in the Adapter power module.
The external adapter 12V power supply is not always subject to repair, especially since the owner can purchase it independently. But, in some cases, it makes sense to open it and eliminate the simple typical defects inherent in converters in pulsed sources. It is necessary to verify the presence of its output voltages and, if they are completely absent, check the power switches and rectifier diodes for a probable short circuit.
In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in emergency short-circuit mode without output voltages, and during short circuit in the elements of the primary circuit, the main fuse and, less often, the current sensor at the source of the key are most often cut off.
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. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM), in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, but there is sound and all other functions work. Sometimes when you turn on the image for a second appears and disappears.
Usually in such cases, a malfunction is detected in the backlight nodes of the LED panel. Often the cause of the malfunction is the lack of current in the LED circuit, for example, an open or short circuit, or a violation of the contact connections of the connectors.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
- The TV does not turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the T.MS6M181.7A 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). In cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - CPU: MST6E181VS-LF-Z1b SPI Flash: 25Q32SIP, Audio: YD1517P which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
If there is no reception of television channels, but the TV is working properly from external devices, first of all you need to check the voltage of the tuner ET-9L1E-E01W and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
Owners and users of the HYUNDAI H-LEDVD22V10 TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!
FIRMWARE FOR SPI FLASH -----------> HYUNDAI H-LEDVD22V10, Main: T.MS6M181.7A 11012, Panel: M215HW01
The appearance of MainBoard T.MS6M181.7A is shown in the figure below:Repair of the motherboard T.MS6M181.7A, which uses the multifunctional processor MST6M181VS combined with a scaler, is advisable to start by checking the power supply of the standby mode, which is implemented using a separate linear stabilizer 3.3V. Further, 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 2.5V is required to power the DDR W9425G6JH memory. If there is a backlight and no image, the power of the LCD panel 5V or 12V, depending on the type of panel used, it is advisable to measure directly on the LVDS connector. If the TV does not exit Stand-by, does not respond to the remote control and control buttons, update the SPI FLASH software.
