HYUNDAI H-LEDVD22V2
General repair guidelines for TV LCD LED
It is advisable to start the repair of the HYUNDAI H-LEDVD22V2 TV with a careful external examination of both internal and external elements. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. 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.
If the H-LEDVD22V2 TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power supply module. In some cases, only the stabilizer or power converter of the control processor may be faulty, which is typical for some HYUNDAI models. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is cut off in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM controller chip are subject to verification, which it is desirable to verify by replacement.
In cases where the HYUNDAI H-LEDVD22V2 TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of a malfunction of the LED driver (converter for powering the backlight LEDs of the M215H1-L01 panel). 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.
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.
On the CVMV26L-B-20 motherboard, in case of a malfunction, you should first check the performance of all the stabilizers or power converters of the microcircuits and, if necessary, update the software (software).
In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - CPU: TSUMV26KE-LF, EEPROM: 24C32, SPI: 25F40, Sound: TDA1517P. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
Before replacing the F21WT-3BAR-E 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).
Once again, remind users! Attempts to self-repair a HYUNDAI H-LEDVD22V2 TV without the appropriate qualifications and experience can lead to its complete non-repairability!

Attention! The HYUNDAI H-LEDVD22V2 LED TV panel M215H1-L01 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.
