SOURCE: Stopped working
I had a similar problem with a jvc 8040. when I replaced the fuse it became very obvious that the b1560 output on the center channel was blown (smoke and sparks, always a dead giveaway). I haven't fixed the center channel yet but simply unplugged the center channel board and removed it from the unit. Now everything works fine except of course the center channel. Pre outs still operate just fine so a slave amp could be used for center channel power, or you could just go and buy a marantz amp; I did and then I realized that I was lucky that the old jvc quit.

To solve this type of problem, you need a piece of white chalk. Draw a line around the area where the set is at. Call a priest - and lay the poor thing to rest!!!! This isn't the first time Samsung has "dropped" junk onto its' customers. Their dvd players also had problems with their DSP I.C.s that would over heat and cause the video playbacks to "break up". Don't waste any more time or money on the product!!!!!

Logic Control D Board got nothing to do with this problem. This is your main power supply gone bad(usually not the sub power supply). I just repaired my VIZIO by replacing main power supply. Just remove back cover and your board will be right in the middle of the screen. Just get board part/serial # and google it. My best price was through eBay(around $100). Everything is fine now.

WELL FOLKS I just FINALLY found what I have been searching for, I own a Sharp LC 32SH12U LCD TV that has begun to show problems with it's picture, Now it's sound is great no change..But it has gotten to the point that when i first turn it on all I get are three or four bright WHITE lines on the right side of the screen. They are a bout one third from the very corner of the screen.After it warms up for a while, MOST of the time it will just pop up and go to working just fine, that is what was giving it away to me that it HAD to be a something generally easy to fix, And in all of my searching I FINALLY found what I was looking for..Rite here on FixYA.com...There it was right thre in PLAIN ENGLISH..(( The T-CON BOARD )) Timing Control or LCD Controller..Board. on teh LCD panel Assembly, It transfers the image signal of the TTL and LVDS signal to specific TFT but What you all really NEED TO KNOW is JUST what is going on with your TV set when the T-CON Board is going bad, And I am about to tell you....So her ya go.. If you TV has any of these symptoms Well then I can pretty much say that your T-CON Board is bad or going bad...OK..If you have A Scrambled Picture,LINES,multiple Pictures Color smears, blotches, Rolling Pictures after warm up, Blown Surface mounted Fuse No Picture, Very Dark Screen almost like there is no backlight....Folks if your SHARP LCD TV is doing ANY of thsi then you just may need to replace your T-CON BOARD!!!! Hey it beats buying a new TV RIGHT!!!! GOOD LUCK FOLKS!!!!! I have already bought my replacement T-CON Board, as soon as I get it and install it I will let everyone know how it went!! PLEASE CROSS YOUR FINGER"S AND PRAY THAT THIS WORKS FOR US!!!! Thanks Wade in Eastman Georgia...

Coming off the T-com board, there are two ribbons going to two long boards attached to the screen. Which can not be replaced, there part of the screen. You might be able to fix the screen board, if you can find the bad part and change it. If not the TV is junk.
