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.
Buffer boards or Y-SUS main needs to be replaced. What do you mean by motherboard? The power supply board or the Logic or X main.... They YBU/YBL and the YSUS work in unison. Y-Buffer upper controls top half, Y Buffer lower control bottom have YSUS controls both of those. There is also D, G, E F boards that can split screan. But they to are controlled with the Y-SUS Main. Hope this helps...
I have Lg 29" color tv.and now the screen display size is getting increased(wider) . so the image(video) is getting pixelated. and also channel logos are cutting off from the screen./,,........
please let me know wats the problem and how to solve it .......
Looking at it from the back, the board on the left is the ysus. You should see a big red cable coming from the power supply board in the middle of the set going to the ysus. Near the red cable plug on the ysus should be a fuse. Most likely the fuse has blown. If it is you need a ysus PCB. Check out encompassparts.com. If you get a new board be sure to set all the controls on the new board to match the old board. If you don't you will have little sparkles all over the screen when it comes back on. I hope this helps. You may want to check all fuses on the power supply and the zsus which is on the right side of the set. I have seen both the ysus and zsus be bad together. Good luck and thanks.
