General repair guidelines for TV LCD LED
Fault diagnosis and repair HYUNDAI H-LED32V8, as well as other electronic devices, it is recommended to start with an external examination of the external and internal elements. According to some external signs of a change in the state of some elements, it is sometimes possible to make assumptions about the nature of the defect, as well as determine the further direction of the troubleshooting. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
In the case when the H-LED32V8 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink lights and does not show any signs of operability, the SHL3230F-101 Rev5.0 power supply module is probably faulty in this case. If it is serviceable with such manifestations, it is necessary to check the stabilizer (converter) of the processor power supply on the motherboard. In general, 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.
The reasons for the breakdown of the power switch in switching power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or broken resistors in its bundle.
If there is no image when you turn on the HYUNDAI H-LED32V8, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the circuit of the panel backlight LEDs, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
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.
Repair or diagnostics of the 40-MS8200-MAD2XG motherboard should begin by checking the stabilizers or power converters of its microcircuits. If necessary, update the software (software) with the replacement of SPI FLASF, especially if it is from the manufacturer WINBOND. Firmware included.
If the TV works normally from external devices, but does not tune into television channels, the TDQ-3CB tuner may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals, as well as the power supply of varicaps (30-33V).
It should be remembered! Attempts to repair the HYUNDAI H-LED32V8 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!

The appearance of the MainBoard 40-MS8200-MAD2XG is shown in the figure below:
40-MS8200-MAD2XG
40-MS8200-MAD2XG can be used in TVs:
ERISSON 39LET30 (Panel V390HJ1-P01), ERISSON 32LET30 (Panel V32D30-CSOT V2), FUSION FLTV-23L18B (Panel LTA230AP01), GoldStar LT-19A310R (Panel M185XW01 V.F), HYUNDAI H-LED32V8 (Panel T315XW06 V.8).
Main features of the HYUNDAI H-LED32V8 device:
Installed matrix (LED-panel) T315XW06 V.8.
The matrix control uses the Timing Controller (T-CON) 315HW07.
The LED driver SSL320_0E2B is used to power the backlight LEDs.
The formation of the necessary supply voltages for all nodes of the HYUNDAI H-LED32V8 TV is carried out by the SHL3230F-101 power module, or its analogs using MP2127 microcircuits.
MainBoard - the main board (motherboard) is a 40-MS8200-MAD2XG module, using MST6E182VS-LF-Z1 chips, Flash - 25Q32BV and others.
The TDQ-3CB tuner provides television reception and channel tuning.

Attention! The 32-inch panel of the HYUNDAI H-LED32V8 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!
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.
