General repair guidelines for TV LCD LED
Fault diagnosis and repair HYUNDAI H-LED22V1, as well as other electronic devices, it is recommended to start with an external examination of the external and internal elements. Sometimes, based on visible changes in the components of the device, it is possible to draw some conclusions and determine the direction of further troubleshooting even before the necessary measurements are taken. In most cases, the repairman can guess the causes of the defect and possible consequences by the characteristic signs of typical TV defects, for example, ring cracks formed in the soldering of element leads, swollen rectifier filter capacitors, charred resistors and other circuit elements.
Malfunctions of the power module RS-330-120-S325 12v 3v3 can be expressed in different ways, for example, the HYUNDAI H-LED22V1 does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. 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.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip can also cause a breakdown of the power switch of the converter.
In those cases when the HYUNDAI H-LED22V1 TV has lost an image, and the sound is there and all the other functions are functional, there is a possibility of a malfunction of the LED driver (converter for powering the panel backlight LEDs). When you turn on the TV, the image may appear briefly and disappear immediately. It must be borne in mind that with such manifestations the LEDs themselves also fail.
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 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.
If the motherboard is faulty T.VST26.7A, first of all it is necessary to check all the linear stabilizers or power converters of its chips, as well as, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - 1517, MP1423DN (8), 25Q80BVSIG (8), FT24C32A (8) with new or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
If you suspect a TDQ-ATF27WT-F tuner malfunction, first of all, you need to make sure that the varicaps supply voltage (30-33V) is on the corresponding output of the tuner, as well as other voltage supplying it.
For owners of the H-LED22V1 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!
