General repair guidelines for TV LCD LED
Possible malfunctions
- The HYUNDAI H-LED29V17 TV does not turn on. There are no signs of operability. The indicators on the front panel do not light up and do not blink, the TV does not respond to the control buttons.
Often in such cases, the 168P-P29EWB-HCW0 power module is faulty. It is necessary to measure its output supply voltages, and in case of their absence, check the operability of the power switches (7N65) of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In the event of breakdowns in the secondary circuits of the converter, it can usually fail in short circuit mode, and in the event of a short circuit in the power elements of the primary circuit, the mains fuse or current sensor at the source of the key most often breaks.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback circuits (OOS) of stabilization. PWM controllers (PWM) OB2273D, if they do not have visible damage to the case and open short circuit between the terminals, are usually checked by replacement.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
As a rule, in such cases there is no display backlight. 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 check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can check each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN junction indirectly indicates a LED-a
- 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 5800-A8M280-0P10 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software). Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing flash elements: Q32B-104HIP, tuner: ET-9Z2E-CF106H requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can sometimes be diagnosed by warming up.
In the absence of tuning to the channels of on-air or cable television, you should make sure that the software is correct, as well as in accordance with the ratings of the supply voltages at the terminals of the ET-9Z2E-CF106H tuner. It is also necessary to check the presence of pulses of data exchange between the tuner and the processor via the I2C bus using an oscilloscope.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Entrust repair to professionals with sufficient experience in the field of repair of electronic equipment.

5800-A8M280-0P10 can be used in TVs:
AIWA 32LE6110 (Panel T320HVN01.V2), AIWA 24LE6110 (Panel V236H1-LE4 Rev.C1), HYUNDAI H-LED29V17 (Panel V290BJ1-PE1 VRev.C2), SUPRA STV-LC24660FL (Panel HM236WU3-100), SUPRA STV-LC19660WL (Panel E185SG01), SUPRA STV-LC19663WL (Panel E185SG02).
Main features of the HYUNDAI H-LED29V17 device:
Installed matrix (LED-panel) V290BJ1-PE1 VRev.C2 or SEL290E1 S00B (16) Rev.R1.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the OB8362HP PWM controller. As power elements of the LED driver, keys of the type ME15N10-G are used.
The necessary supply voltages for all nodes of the HYUNDAI H-LED29V17 TV are generated by the 168P-P29EWB-HCW0 power supply module or its analogs using OB2273D microcircuits and 7N65 type power switches.
MainBoard - the main board (motherboard) is a 5800-A8M280-0P10 module, using flash chips: Q32B-104HIP, tuner: ET-9Z2E-CF106H and others.
The ET-9Z2E-CF106H tuner provides television reception and channel tuning.

Attention! The V290BJ1-PE1 VRev.C2 SEL290E1 S00B (16) Rev.R1 panel of the HYUNDAI H-LED29V17 LED TV 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!
