    We just found out that Toshiba has replaced 2 boards and made them into one to fix the problems of their plasma tvs. We are awaiting an answer to see if they will pay for it also since we tried unsuccessfully to fix the problem at a cost to us which never fixed the problem and we finally just put the tv into a room and could not use it at all for a year.

Three suggestions:
Contact http://www.ptscorp.com/television.html. They have a selection of replacement boards or will repair it Fees are usually $50 to $125 and I have had great success with them.
Another would be to try www.shopjimmy.com and lastly do a Google search, if you know the exact part number, to find other sources for the board.

No screen boards found. Do you mean any of these?
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 might be time to start testing different boards to see if they are functioning properly.

Main Board

The main board 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. Main boards might also be referred to as a motherboard, main module, or an A/V 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, as 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 pixelation 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 might 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 boardaddresses all the individual lines of display. When one board breaks down, it probably will not affect the functionality of the other. However, it might be a good idea to have both replaced because X-SUS and Y-SUS boards have a relatively short life span anyway. A failure of one could mean an impending failure of the other.

Buffer Boards

B uffer 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.

42" Plasma, no picture, sound


Hi:
The best possible solution to your problem is to replace both sustain boards at the same time, The X and Y sustain boards. LG tech support recommends replacing the digital board as well when replacing their boards, even during LG's tech training seminars they suggest you replace all major boards for continued viewing enjoyment. But in my experience you should replace the X systain also, but make sure the Y you replaced is still good.

I have no picture.


Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

Hope this will help in solving the problem.....

Hi,

You can solve this type of problem by opening the television, but caution must be taking to ensure proper troubleshooting, because the panel contains high voltages.

often that needs to be done in a service center as there are some adjustments to be made after replacement.

Hello,
IF the backlights are on but you just get dim glowing on the screen when look at the screen in darkened room then the T-CON board is bad or it is not getting the 12vdc from the main logic board. Need to use logical troubleshooting before buying the wrong parts, but if otherwise then,

I have a 42" lg plamsa tv the screen went black and still had sound.. found a blown fuse on the board to the right of the power board, when i replaced the fuse,it will power up and then 5 seconds later i...


The fuse you have replaced would have been on the sustain board, now that it clicks indicates a problem either with the control board or the sustain board. You would need to disconnect the connector from the power board to the Y-sustain board (left of power board) to check if the Vs & Va voltages are present, if so then the power supply will be working ok & the problem will be with the previously mention boards. There is the possibility that the plasma display screen could also be faulty.

I had the same problem. We replaced the Y Sustain board. It was under $200 and not at all hard to do yourself. Remove the back of the tv. Make sure you watch what screw goes where. You will see the board on the left side. The number should be on the bottom right corner of the board. Just watch how you removed the board making small notes as to what goes where. Its really not that hard and you can save 600$ or more
