The cause: damp.
Easy solution: press on left side of screen. Voila!

Longer answer:
The connection between screen and computer is made bij means of a long, small horizontal strip with multiple connections in the vertical plane.
The strip sits loosely between the left side of the screen and the print.
When damp occurs the connections between the screen and the computer can be lost.
Helping to re-establish the connection by means of light pressure on the left side of the screen solves the problem.

I have the same problem and I think it is caused by the sun (heat) on the screen plus it being housed in a sealed plastic mounting " Box" which is attached to the steering station on my sailboat. The box has no ventilation access. When it is a hot day it goes vertical and then overnight it cools down and works fine the next day.

Lousy product design in the first place plus the box is asthetically nice but not suitable even though it appears to be specifically meant for the C70. Rebooting the system as suggested by Raymarine does not work - it wont react as it is too hot.. I once hired a local technician to check it out - $100 later, he had taken it apart and put it back to together and it worked again - obviously it cooled down when open.

Raymarine products are not on my wish list - never again. I have no idea as to whether drilling a few holes in the sealed box would help but dont want to risk getting moisture in there.

Hope this helps. Geoff. S.

Vertical lines showing up after being on for awhile


Eh, I can't be too sure, but it sounds like it's either a heat issue, a signal issue, or a backlight issue. Either way, if it's still under warranty I'd send it in.

Good morning When I switch on my C70 i have not the normal screen, only vertical lines. Sometimes the screen works, but next time the same problem appers...vertical lines e can't use it. Can you help...


I recognize the problem. It mostly occurs when the plotter is exposed to moist during some days. The contactstrip which connects the computer to the screen gets moist and does not conduct in an optimal way. The result is a non readable screen with stripes

The solution is simple: press on the edges of the screen and the contact is re-established.

LCD monitor have Vertical lines and black colour become greenish


normally the 19" resolution can support up to 1280*1024, but if it comes with vertical lines in full screen, it might indicate the panel is no longer to work and probably it's time to replace new one.
