Yamaha QY70 light modification

This article is not the ultimate solution to illuminate your QY70 display. I hope to find a better kind of LED for a more equal lightning of the display. Feel free to experiment and provide feedback to make it the ulitimate solution!

The photos will show the process of placing the LED in the QY70. Please note there is not yet a description where to tap the 3 volt.

The pins of the LED has to be bend to fit the PCB. This type of LED needs to be cut a little to fit the housing.

The LED does illuminate the display just a little more. Perhaps some sort of LED or light will spread more nicely. Make sure no dust is on the inside of the window and the display, for they will be very visisble.

Proof of Concept

This article is only a proof of concept. An experiment to proof internal light is possible, but much more research is needed before I can present this article as a proper modification manual.

Any modification to your QY70 is for your own risk. I can't be held responsible for any damage.

Please let me know if others kind of LED will increase the visibility.
