How to Add a Board on the MA5600?


You can add a board on Huawei MA5600 in the following two ways:
· Adding a board offline: Run the board add command to add a board to an vacant slot (in this case, the system generates the "Board Fault" alarm). Then, insert a board to the slot (in this case, if the type of the inserted board is the same as the type of the board added offline, the system generates the "Board Recovery" alarm; if the type of the inserted board is different from the type of the board added offline, the system generates the "Type Mismatch" alarm).
· Automatically discovering a board: Insert a board to an vacant slot (in this case, the system displays a message indicating that a board is automatically discovered, and the board is in the auto-find state). Then, run the board confirmcommand to confirm the board that is automatically discovered.

This way is also can be adopted by Huawei MA5616 equipment.

Is There Any Changes in the Board Software Version After a Service Board Is Replaced?


fter a service board is replaced, the control board checks and determines the software of the new service board.
1. If the IO board package file contains the new service board, the control board updates the software of the new service board to that of its own.

If the new service board supports the anti-downgrade function and the control board software is within the anti-downgrade version range, the new service board runs with its default software.
If the new service board supports the anti-downgrade function but the control board software is not within the anti-downgrade version range, the control board updates the software of the new service board as that of its own.
If the IO board package file does not contain the new service board, the software of the new service board is loaded to the IO board package file of the control board.

Vizio LC470DUG powers on for 4 seconds than goes off--possible mother board


No such thing as a mother board in a TV set. Here is a list of the PCBs
Types of TV Boards Every TV uses a collection of various boards to perform every function imaginable in a television. The boards work together to produce sound and images on a television screen. When certain mechanisms in a TV fail, it may be time to start testing different boards to see if they are functioning properly.

Main Board

The main board, or motherboard, is the central hub of a television circuit system. The easiest way to identify a main board is to find the board with the various video and audio inputs/outputs. Generally speaking, main boards also contain a tuner, HDMI, USB, and S-video port. Main boards are one of the largest boards in a television. This part is also sometimes called the main module or the A/V (audiovisual) board.

Power Supply Board

Another large and important board inside a television is the power supply board. Usually found in the center of the TV, the power supply board has several connectors that supply power to the other circuit boards. It can contain transformers, large capacitors, and integrated circuits. There is usually a table on the power supply board indicating the different voltages it produces in addition to the signal names.

Inverter Board

Found on LCD TVs, inverter boards are used to mount the LCD backlight. These are smaller boards, usually shaped like long, thin rods. If an LCD TV's screen is dark, distorted, or difficult to see, it can be the result of a defective inverter board. Inverter boards fail when inadequate power is not allowing current to pass through the backlight bulb.

Timing Control Board / Logic Board

The timing control board, known as the T-CON board, is typically only found on LCD and LED TVs. Plasma TVs, on the other hand, use a logic board. The functions of the logic and T-CON board are similar: each functions to digitize the information it receives from the TV's processor. This allows the screen to display images on the pixel level. When the T-CON or logic board fails, the screen images may become distorted, leading to pixilation and the appearance of lines on a television. On a logic board, there are slotted connectors on all four sides, while T-CON boards have connectors on just two sides.

X-Sustain and Y-Sustain Boards

Also known as the X-SUS and the Y-SUS, the x-sustain and Y-sustain boards only appear in plasma screen TVs. The X-sustain board may also be called the Z-SUS. These boards function similarly, producing proper screen images. Although they serve pretty much the same function, the two boards work independently of each other. The X-sustain board activates all the display lines at once, while the Y-sustain board addresses all the individual lines of display. When one board breaks down, it probably does not affect the functionality of the other. However, it may be a good idea to have both replaced because X-SUS and Y-SUS boards have a relatively short lifespan anyway. A failure of one could mean an impending failure of the other.

Buffer Boards

Buffer boards are also only found in plasma screen TVs. Connected to the Y-sustain board, a buffer board works to turn output to the plasma display. Common defects of buffer boards include the burning and shorting of power lines.
