I replaced mine, it's called the Deflector board. Some people call it the flyback board after the flyback transformer that is located on it. I found one on Ebay for 25 bucks a while back, so good luck. Troll ebay or find someone that is giving their tv away on craigslist because the convergence or a bulb is bad. Don't base it just on your specific model of TV though because many of them share this common board.


Try part #271827. That was the part number of the board I won on Ebay.

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.

Tv fell off the stand onto a carpet floor now wont turn on


Possible that the fall has damaged the mother board and so there can be CRACK ON THE MOTHER BOARD. So you need to remove power cord and check using a good inspection lamp on the board for broken circuit board. Use a good soldering iron with wire strips to join - take care not to short circuits as each line must be tested for short and continuity.
