Replacing backlight with LEDs in Raymarine E-Series E120 display

Just put a meter onto the power cable.

Most boats have some sort of battery gauge also.

I stopped doing this a while ago but 24v systems don’t work with my LED set up.

I tried all kinds of things and ended up using a separate back light and dimmer switch on for a commercial boats 24v set up.

Hi

Fantastic. many thanks

Thanks for all your work on this, it seems like a great and practical fix.
 
Hello,

Thank you for the very detailed instructions and tips. I have to test the functions at home. Which 12 V power supply can I use? 12 V but how many watts and amps?
 
Hi

Thanks to the comments and the videos on YouTube. I did the "repair" this afternoon in 5 hours.

Material used:
1 x Infineon Technologies IRLB8721PBF MOSFET 1 N-Canal 65 W TO-220AB
1 x Arcol MRA0207 100RBTA15 MRA0207 100RBTA15 Metal film resistor 100 Ω 15 W
Some of Arthelme 51541434 LED strip 12 V 5000 mm cool white 5 m

I bought a digital soldering station for up to 480 °C and a desoldering suction pump. The pump is very helpful for removing the old parts.
To do the desolder I had to set the temperature to 480 °C and needed a screw driver to lever the pins out.

I used the tips of Murve about the LED strips. I'm very happy with the result and saved a lot of time. It dosn't look beautiful, but it works.
The corners I fixed with hot glue so they can not get lose during the time.

To test the unit I used a power supply with 12V 1.5A 18.0W
