The picture shouldbe free of vertical or horizontal lines.

1. If the lines are present on the TV screen, press the SMARTbutton. on the remote control and select Settings> SUPPORT > Picture Test.
2. This menu will appear on the test picture. Select whichoption best describes the result you have.

A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color. https://itstillworks.com/causes-horizontal-lines-lcd-panel-37988.html

Lines or Banding Within the Image

If the scanner is generating lines or banding within the image during preview and/or scan, below is a list of possible solutions.

Horizontal Lines: If the lines run horizontally throughout the image, it is almost definitely interference of some kind. First thing to try is reverse the cable (Astra series only, except for 2400S), trying with and without termination as well. It could also be the SCSI card itself that is causing the interference. Try reseating it in a different slot, away from other cards. Try moving the scanner itself to another location, farther away from computer components such as monitors and CPUs. If none of that works, search for the file ?prescan.dib? on the hard disk and delete it, then try the scan again. If that still doesn?t work, follow the clean uninstall and safe mode install of our software. If these troubleshooting steps do not work, it could be a physical defect within the cable that?s generating extra interference, and the cable should be replaced. If the cable has been replaced already, it may be the UDS-IS11 itself generating the interference from being defective. Replace it.

Vertical Lines: If the lines run vertically throughout the image, it is probably a hardware problem, most likely with the scanner itself. However, follow the cable-reversing instructions above, remove the ?prescan.dib? file, and try the scan again. Often, if they are thin lines they are from dust within the optics. Open the case and blow out the dust with compressed air.

Your best bet is to contact Furuno. Replacing the LCD in those displays is very time consuming. I recommend writing your waypoints down or transferring them to a computer while you can still somewhat see the screen.

I don't beleive this is goning to fix your problem. Open the dome and visually check that it is spinning. There is a maintenance menu though. To open the maintenance menu;
1. Turn the radar on.
2. Wait until the initial screen appears, then press and hold UP and DOWN keys together.
3. In about 10 seconds, the maintenance menu as shown below will appear.
4. Press MENU key to close the menu.

You are misleading yourself. When you have a horizontal line across the screen it means that the vertical circuit is not working. You see, the vertical circuit moves the beam up and down which is not happening. The horizontal circuit moves the beam left and right and it is working. Your set probably needs a new vertical output IC and some electrolytic capacitors that work with it. The caps dry up with time and harm the output IC.

The damage could be either in the LCD screen or the connection cable. Open the screen assembly and check the connection cable first.
In case it doesn't work you can find replacement LCD screens here.

There are two types of lines.

Lines caused by a bad LCD screen and lines caused by poor sync.

A bad LCD will cause perfectly straight vertical and horizontal lines that don't move at all. This is because the row and column addressing ICs have gone bad, so you will end up with rows or columns of bad pixels.

Poor sync looks more like what you are describing. The picture will flip vertically and horizontally.

Poor or missing sync can be caused by a bad video cable, or a bad IC on the main board.

If the monitor has a removable video cable, borrow another one from a friend to test if the monitor is working. If it works, head to your local computer store and buy a new cable.
If the monitor still doesn't work with a different cable, you may have a bad main board. The only way to repair the monitor will be to replace the board.

If you open the monitor, be sure to check for bad capacitors. They can cause all sorts of strange faults. Look elsewhere on this site for how-tos on inspecting capacitors.

If your video cable is not removable, there's not much you can do. You will need a way to test that each pin on the cable connector on the main board conducts to a corresponding pin on the other end of the cable. You can do this if you have a multimeter, or a continuity tester.

Hi...there,

Yeah, there it... It's called a AD board. It that piece of component were you plugged your VGA or DVI cables to it. Panel scratchs repair kits, not recommended. Beside your panel could be already damaged by this problems you had. Replacing the AD board gonna cost you though...any where from $70.00 or more... My recommendation, just get a new one...saved you the headached and $$$.
Have a nice day!
