Question about Humminbird NS25 GPS Receiver

Open Question

NS25 Screen gone

On my NS25 is suddenly an about 5 cm long and 4 cm high white stain, i.e. in this area is nothing readable any more. Does anybody know where to buy the Sharp LM32K072 screen to replace the spoilt item? I'm concerned to change the system as I am quite happy with the C-Map for the Singapore water area and would not like to redo the complete installation + map purchase because of this. Thanks in advance Al

Please check the mount and the wiring throughly as its a loose contact issue nothing else.

White Screen, Video is readable but faint

Any time there is a distortion in the picture/graphics on the screen, this is an indication of a defective LCD display. LCD displays can fail even if the screen isn't cracked. It sounds like the graphics are washed out. More info on defective LCD displays can be found here:

I have 5 white dotted lines running horizontally across my nuvi1490lmt. Does anybody know why this would be?

Yes, this is caused by a defective LCD display, There is nothing that you can do to make them go away. It is caused by a defective transistor in the LCD display logic that is either stuck on or off. The transistor controls a single horizontal line across the screen. The only way to fix this problem is to replace the display.

The display on my C70 will suddenly go to a series of vertical lines. Sometimes light finger pressure on the display will cure it. What is the permamant solution

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.

The screen on my Forerunner 201 is suddenly blank. Is charged. Wasn't dropped.

I left the unit on to run the battery down completely, then put it on charger and the screen was readable again.

here's a user manual/installation manual for your sounder:
If the depth sounder portion works, I would suspect the settings are off (check first) or the gps circuit needs repair.
Best of luck!

The wiring within the Screen unit seems to be very poorly done, there are 4 cables to the GPS side of things and these can contact each other as there is a portion of the wire where it enters the connector that is bare, and if these touch one another then you will get nothing.
Dismantle the head unit and check the cables, i would be inclined to shrink wrap the bare portion of each cable.
Hope that this helps, it might not be the answer, but it is worth checking.

This is a common problem on lots of boats with any brand of electronics. Most likely it is being caused by a bad crimp in a wire connector, or by having too many connectors on a terminal in the power supply bus. Start at the power supply source and ground and replace any butt or terminal connectors with high quality heat shrink connectors (such as Ancor). Make sure that the connector is the right size for the wire.

On Humminbirds the problem could also be in the swivel mount that holds the power and data cables. The cables should be held in place by a metal bracket which is located under a panel held onto the swivel bracket by to small philips head screws. If any of those components are missing, the plug may be loose in the socket which could cause it to disconnect temporarily when the boat hits a wave. While you have it apart check the plug and the socket for corrosion.

I hope this helps. Please contact me if you have any more questions.
