In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

REPAIR / SERVICING TV HYUNDAI H-LED32V16

Technical description and composition of the HYUNDAI H-LED32V16 TV, panel type and applicable modules. The composition of the modules.
HYUNDAI LED
Model: H-LED32V16
Chassis / Version: T.MS6M181.6A
Panel: CX315LEDM
MainBoard: T.MS6M181.6A
IC MainBoard: FLASH: EN25Q32B
Tuner: CDT-3SP5F3-36
Technical Specifications H-LED32V16
HYUNDAI H-LED32V16
General repair guidelines for TV LCD LED
Repair of the HYUNDAI H-LED32V16 TV should begin with a careful external examination of all its components and modules. Often, by the visible signs of a change in the state of some elements, one can judge the causes of the defect. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a significant clue in the assumptions about the causes and consequences of the malfunction.
If the HYUNDAI H-LED32V16 does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a power module malfunction. In some cases, only the processor power regulator may be faulty. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should begin by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
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.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but the sound is there and other functions work, there is a high probability of a malfunction of the LED driver (CX315LEDM panel LED backlight power converter).
A malfunction in the backlight circuits often occurs due to an open in the power circuit of the LED lines. It requires disassembling the panel and checking the LEDs themselves, the rations of their terminals, as well as the reliability of the connections in the connectors and rations of the terminals.
It is impossible to check the line of series-connected LEDs without a special current source, and for this purpose it is not safe to use any voltage sources above 12V for them. Then it remains only to open the panel and check each LED separately. Usually, Chinese 9V-powered multimeters light up one LED slightly if you connect the probes in the forward direction, the red probe to the anode, and the black to the cathode.
If the motherboard T.MS6M181.6A is faulty, first of all it is necessary to check all the linear stabilizers and power converters of its chips, and also, if necessary, update the software (software). Sometimes you can check the health of MB only by replacement.
Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - FLASH: EN25Q32B and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
If the TV works normally from external devices, but does not tune into television channels, the tuner CDT-3SP5F3-36 may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals. Sometimes the cause of the inoperability of the tuner may be a software failure.
Owners of the H-LED32V16 TV are advised to contact qualified personnel with experience only for repair! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

FIRMWARE FOR SPI FLASH  ----------->   HYUNDAI H-LED32V16, Main: T.MS6M181.6A, Panel: CX315LEDM


 If a failure occurs in the SPI FLASH software from Winbond, we recommend that you replace the chip with a new one. Often, unreadable Winbond microcircuits can temporarily restore their functionality after a strong temperature exposure, for example, heating with a soldering station or a lighter. Sometimes this is enough to read its regular contents.
Repair MainBoard
The appearance of MainBoard T.MS6M181.6A is shown in the figure below:
Repairing the motherboard T.MS6M181.6A, which uses the multi-function processor MST6M181VS, combined with a scaler, it is advisable to start by checking the power supply of the standby mode (Stand-by), which is implemented using a separate linear stabilizer 3.3V. Further, in the operating mode, it is necessary to check the operability of linear stabilizers or voltage converters necessary to provide power to the processor nodes: 1.2V, 2.5V, 3.3V. A voltage of 2.5V is required to power the DDR W9425G6JH memory. If there is a backlight and no image, the power of the LCD panel 5V or 12V, depending on the type of panel used, it is advisable to measure directly on the LVDS connector. If the TV does not exit Stand-by, does not respond to the remote control and control buttons, update the SPI FLASH software.
T.MS6M181.6A can be used in TVs:
AKAI LTA-32L09P (Panel LTA320AP05), ERISSON 32LEN60 (Panel LTA320AN01 D02 ), ERISSON 32LEE01 (Panel 720p HD 1366x768), HAIER LE32Z50 (Panel T315XW06 V5), Hyundai H-LED32V6 (Panel HV320WXC-100), HYUNDAI H-LEDVD32V6 (Panel V320BJ2-P01), HYUNDAI H-LED32V16 (Panel CX315LEDM).

Attention! The CX315LEDM panel of a HYUNDAI H-LED32V16 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.
