Reverse Glow LCD Screen !!@2004/04/03 Related VWvortex Forum
I installed VW Corrado VR6 Euro Illuminated Gauges with Glow Rings. However, the back light of LCD was too bright. Okay Modify LCD! FD



The stock LCD back light doesn't match DDI Illuminated Gauges. TOO BRIGHT!

How to

Please check the gauges mods page of CCC.
Remove the cluster from the dash
and
Changing the LCD green colour



Thanks Michael and Anh.
Remove the T8 torx screws from behind the circuit bard for take off the LCD housings.
Pull out the front black cover.

On the front of white housing you will see the LCD glass

This glass has thin polarizing filter to the surface.

Carefully remove the Polarizing filter from the front of the LCD glass.
Start to peel it up with a razorblade.

If you do happen to damage your polarizing filter, you can look around your house for some old things you do not use that have LCD's. or E-mail me.

Then carefully lift it off with your fingers.

Clean the filters and LCD's using 99% Isopropyl rubbing alcohol. Wet the adhesive, then rub in one direction with your finger until it peels off.

After it is clean, You can see a LCD screen transparent through the filter.

Reinstall the polarizing filter on the LCD so that it appears black. ( Just flip it over )
After reinstall, its all black.
I just set it in place and carefully re-assembled the cluster.
MFA Segment check mode.

Excellently, it reversed.
Put them back in my car.

Awesome!
The backlighting turn on.

Best match DDI Illuminated Gauges.
I had better change the backlight of the LCD into the EL illumination.

I could not be satisfactory to that.

I change the LCD back light color to red.

You can use a translucent binder cover that you get from a stationary store for the filter, or You can also get coloured plastic at an art supply store.


After change color.

Like Audi A4!

hehehe! Looks good

However, hard to see it at daytime. hummmm
I bought a 12V-2W wedge bulb and socket from the motorcycle shop.

2W bulb is too bright, 1w is more better.

This bulb socket is just fit to stock bulb hole.

Take out power supply from fuse box.
Daytime

Nighttime

But, too bright degit.

I WANT THE VARIABLE REGISTER!!

TwinScrew20v(Vortexer) advised me.
I got a good idea, Immediately, I bought a 5 poles relay and fuse holder.
Behind the headlight switch.

58 Headlight switch ON 12V

X Ignision switch ON 12V

58b Headlight dimmer switch resistored power.


The wiring diagram

Connect wiring by the relay to the  headlight switch connector like this.

The two switched power sources should be run to the relay, one from a switched 12v power(X:Ignision ON 12V) and the other the grey/blue stripe wire (58b resistored lamp power).

The relay switch the two power sources when you turn on the headlight switch.
Gauges Cluster light Dimmer switch.

Adjust to the good brightness for your gauges.

Nighttime
