General recommendations for repairing TV LCD
Any repair of electronic equipment begins with an external inspection of the device and diagnosis of the malfunction. In this case, you should visually carefully examine all the elements of the HYUNDAI H3260 TV, both internal and external. Visible damage to elements can sometimes suggest further directions for finding a defect before starting the necessary measurements. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
In the absence of any signs of operability, when the HYUNDAI H3260 does not turn on and does not signal anything with the control lights on the panel, the LX-MP123 power supply module is most likely faulty. The diagnostics of the power supply should always be started by checking the fuse and, if it is broken, it is first necessary to check the rectifier bridge diodes and the power switch for the likelihood of an avalanche or thermal breakdown.
It should be remembered that in the practice of repair, usually the power keys of N-Fet converters do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
It is somewhat more difficult to look for a malfunction in the converter of the power module with an active KKM (power factor corrector).
If the HYUNDAI H3260 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction of the display backlight, or their power converter - inverter. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the inverter itself, including in the secondary rectifier of the main PSU.
Repairing the inverter is difficult because in case of any malfunction or emergency, even with uneven wear of the lamps, a protection is triggered, which turns it off for fire safety. Diagnostics become impossible and protection needs to be disabled.
It should be remembered that in such cases there is a risk of failure of the power elements of the inverter and to take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
On the motherboard MST182VGV6.0-A, tun Tuner: CDT-3SP512-36, in case of a malfunction, you should first check the operation of all power supply stabilizers of the microcircuits and, if necessary, update the software (software). In cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - EN25Q32B-104HIP, AIC2857F, PS331, cFeon Q32B-104HIP which may require replacement with new ones.
Once again, remind users! Attempts to self-repair a HYUNDAI H3260 TV without the appropriate qualifications and experience can lead to its complete non-repairability!

The appearance of the MainBoard MST182VGV6.0-A is shown in the figure below:MST182VGV6.0-A
MST182VGV6.0-A can be used in TVs:
HYUNDAI H3260 (Panel T315XW07 V2), HYUNDAI H-LCD4200 (Panel T400HW04 V.0 FHD).
Main features of the HYUNDAI H3260 device:
Installed matrix (LCD-panel) T315XW07 V2.
The matrix control uses the Timing Controller (T-CON) T315XW07.
To power the backlight, a converter is used, combined with a power supply, controlled by a BIT3251 PWM controller. As power elements of the inverter, keys of the type AOD446, AOT462 are used.
The necessary supply voltages for all nodes of the HYUNDAI H3260 TV are generated by the LX-MP123 power supply module or its analogs using LD7535 microcircuits (PWM 6 pin) and power switches of the MDF7N60B type.
MainBoard - the main board (motherboard) is a module MST182VGV6.0-A, using chips EN25Q32B-104HIP, AIC2857F, PS331 and others.
The tuner CDT-3SP512-36 provides the reception of television programs and tuning to channels.
