Hello, Can you clarify.

What do I need to resolve this problem.

I too have the same problem. I assume it was caused by me moving the unit.

Samsung un55d8000 shaded area bottom of screen


That is not a good sign. Since a TV screen utilizes what is called scanning lines and the data starts at the top zips side to side until it reaches the bottom; so fast you cannot observe that sequence; the same digital lines should be equal all the way from the top to the bottom. When any variation occurs (such as what you have mentioned) the lower light emitting diode rows are compromised. In a sense these lines are working at 1/2 capacity. This could be an issue with the controller and/or other devices on the circuit board. The company Samsung has a technical service department and a technician should be able to test out the problem described. If it is under warranty, have them replace it. It will only get worse in the future.

Without using legrange multipliers, determine the dimensions of a rectangular box,open at the top having a volume of 32ft^3 and requiring the least amount for its construction.


Given a "rectangular" box, the dimensions of side #1 will match the dimensions of side #3.
Similar for side #2 and side #4.

X = width of sides #1 and #3 of the box
Y = height of the box
Z = width of sides #2 and #4

Then, X times Y times Z is 32.

Area of side #1: X times Y
Area of side #3: X times Y
Area of side #2: Z times Y
Area of side #4: Z times Y
Area of bottom: X times Z

So, minimize: 2 * X * Y + 2 * Z * Y + X * Z

subject to: X > 0 and Y > 0 and Z > 0
and X < 33 and Y < 33 and Z < 33

Or, if you restrict X and Y and Z to be integer-valued, you can "brute-force" it,
i.e., try all combinations:

X Y Z MATERIAL_USED

1 1 32 98
1 2 16 84
1 4 8 80
1 8 4 84
1 16 2 98
1 32 1 129
2 1 16 68
2 2 8 56
2 4 4 56
2 8 2 68
2 16 1 98
4 1 8 56
4 2 4 48
4 4 2 56
4 8 1 84
8 1 4 56
8 2 2 56
8 4 1 80
16 1 2 68
16 2 1 84
32 1 1 98

So, '56' is the MINIMUM value:

2 2 8 56
8 2 2 56
2 4 4 56
4 1 8 56
8 1 4 56
4 4 2 56

If you mean the bar goes top to bottom, there are circuitboards that feed the info in small sections top to bottom. But usually one section will be one inch wide. It can also be the screen panel itself. Try a trusted tv shop

How do you make a buttonhole with a Bernina 830?


Hey, I have a Bernina 830 Record. If it's the same machine, set your stitch length at 0 then back it off about 1 to 2 turns. The middle button is your button hole. Got to one and it goes down the left side, #2 is the bottom cross bar, #3 goes backwards up to form the right side of the buttonhole and $4 is the tack across the top, #5 stitches it into place. I have my original manual if you have any other questions!

When you get vertical lines from the top of the screen to the bottom of the screen, it means you have bad LCD panel, you need the new one. It will get worst with more lines as time goes by.

I have have this TV for almost 3 yrs..now have a shaded area on the left side


The dark side of the screen causes of the lamp alignment or prism glass alignment. This is critical you have to consult your LG technician to do this. But if you have any background o repair consult the service manual. Please careful not to touch the prism quarts so that you maintained the clarity of picture and brightness on the screen.
