Samsung Model WA406DJHDWR. Sign nF comes up every time we attempt to use it. It is brand new and we have not been able to use it yet.

NF = Your Washer has tried to fill but was unsuccessful.
Make sure the water faucets are open all the way. Check for kinked hoses.
Check the inlet screens on the fill hoses.
If you use a Flood Safety Device, then please remove the device and connect the water hoses directly to the unit.
Check if the hot water supply hose is connected
You must connect the hot water supply hose because hot water is supplied by the Auto Temperature Control (A.T.C.) function

My daughter received a new Coolpix L22 for Christmas. She just replaced the batteries in the camera and turned it on, but the lens will not extend and the screen is black. There is nothing in the manual...

Go to the Nikon website and contact Support.
If you've done everything right, then I think it might be busted.
When you go to the site you will need to sign up to have your question answered.
I thought it better you do this as they will ask for details about the camera.

TI 84 plus calculator refuses to graph more than one function

Please, read the following, even if you already know some of its contents.
  1. Once you enter an equation, the corresponding equal sign is highlighted by default.
  2. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted.
  3. If one is not highlighted, move the cursor on it and press ENTER.
  4. If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER].
  5. Command PlotsOff echoes on main screen.
  6. Press [ENTER], screen displays Done.
  7. Restart the graphing procedure.
  8. If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.
You should make it a habit to clear the RAM every time you start a new type of problem.

Hope it helps.

The memory button on my TI-84 Plus will not function

If you connect it to the computer using ti connect device explorer you can try to do everything from there. Manage your memory. If you saying the plus sign is broke too, because it is the memory key too. I wonder if you "+">a would work. Just 2nd recall "a" when you need the plus sign. You can store it in any variable you want. Setting up systems to operate your calculator's memory management can be done on command or Entry Line. Much easier with Ti connect. You don't really need the plus sign or memory key to run very good memory management programs. Just remember to download from this site my ti 84 plus silver manual on how unarchive and run programs. I really don't recommend taking the calculator apart, they usually end up broke at that point.

Why wont my laptop run on my lcd hdtv made by Vizio

You must redirect the video output from the laptop screen to the TV.
It usually takes a keystroke combination, depending on your laptop it is hold the FN(function) key(lower left on keyboard close to the Ctrl and Alt key) and press on of the F1-F12 keys on top of keyboard.
You can try one combination at a time until it switches. Your FN key may have a Flying Windows icon and the F1-F12 key may have a TV icon on it.
Let me know if you get it working and please rate this solution.

Start with service mode, Additional functions(looks like * key), then 2,8 together, then addit. func. again. Has to be a fluid motion. If done right you will see a screen with copier, and whatever options the copier has. Hit copier key. Hit function key. Hit panel key. Hit touch key option, hit OK. Then touch the nine + signs. once complete. press reset to get out and test results. Hope this helps.
