Head Unit Appearance Modification...

Disclaimer: The information on this website is for viewing use only. I have not tried this yet and do not take any responsibility for any damage that may occur to you or your head unit.

The head unit I used to exploration was an old cassette player Delco that I bought off of ebay for $10. I plan to use this head unit for the amplifier since my car already has a decent stock one.

This is the back of the front faceplate...

This is the main circuit board notice all of the pushbutton switches and LED's. There are also some bulbs for backlighting the display...

This is a close-up on the LED's and switches. A pushbutton switch consists of two prongs soldered onto the circuit board which break a circuit. When pressed, the circuit is closed and the button performs is function.

This is yet another pictures of the front circuit board, this time with the flash on...

This is a picture of the front of the seek button, unlit...


This is a picture of the seek button backlit by an incandescent bulb...


As you can see, what causes this glow in this particular design is the coloration of the paint on the back of the button....

A possible solution to remove this paint could be to use any kind of paint thinner or nail polish remover. It will take some experimentation.

This is a picture of the diffraction material used to diffracts the bulb's light evenly...notice the ripples...

Now, what does this all mean? Well, you can possibly change the coloration of the head unit's display by removing the paint from the backs of the buttons and repainting them with stained glass paint with your color choice. You would also have to change the LED's to a different color (they are 3mm in diameter if you were wondering).
