Screen gone dim but still readable
 

A few days ago, my nav screen went dim on its own. Does anybody know of a fix? Searching this forum, the problem seems to point to the backlight on its way out. I can't seem to find a recommended fix or someone who has gone through a fix. Any specific detail is appreciated!!!

MKIII (I think?)


Thanks!

Wallie,

I think I may be having the same problem. My screen kind of appears to look greenish and dim.

I know that doesn't help you right now, but I hope to get to the bottom of it. Let me know if you hear or find anything and I will let you know as well.

Too weird...mine did the same thing as well today. came beack up full brightness once, but back out again.

I have the same issue, i disconected the battery once and the screen corrected on reconnect e.g., I re-booted. it was fine for 6 months but now its a day by day issue, somedays dim, somedays perfect.
Ambient temperature has no effect......

Anyone know the problem or cure?

Replace LCD screen
or
Repair LCD screen if you have access to the manuals/knowhow/etc.
or
Send to Alpine Repair Center
The entire On-Board Monitor Screen is made by Alpine so ring the central Alpine service facility in your country to find if they offer a repair service for the unit. Some countries do, some don't.

I have seen this problem come from two different causes.

1. The CCFL lamp in the LCD has reached its end of life (get a new LCD)
2. The DC-DC converter on the main board has failed (most common cause).

Open it up and take a look for burnt bits. They are obvious to the those who have a sharp eye!

Finding the replacement part is the challenge.

There most be something in the air. My 16:9 display is getting dimmer too. It seems related to temperature. It is darkest on cold mornings when I start the car. It usually gets a bit brighter by the time I get to the office. It is hard to read on cold days in sunlight.

Same problem here, did you ever find a solution?

Thanks!

I have the same issue day by day!

My issue seems to be pretty day by day. I am not sure if it is temperature dependent. I have been less worried about it and busy fixing my license plate annoying alarms. One of the bulbs kept going off and I finally figured out it was because the bulb was loose.

Wish I had more info on the navi screen. I did try to take out and make sure all cables were tight and they were. I think I am about used to it anyways now. It is like permanently in a night mode (not because of settings though). I think it is just dying :( I might buy another one ebay....they are not THAT expensive...but you don't know what you are getting really so...its a risk. We'll see. Robert

age? LCD have a limited life span

My '04's been back to normal mode after a 3 week stint on the dark side. I understand bulb failure etc but ive been cycling through this for probably close to 2 years.

My local dealers say theyve "never seen this" which i dont beleive, too many people here seem to share the same problem.

Does anyone know where we can obtain repair manuals on the screen

MY X5 is 08/2005 manufactured date.

I fixed mine!!!

Like the others here, my screen would start dim and slowly brighten up. Also, if I set the brightness to maximum to compensate, it would "forget" the setting the next time I started the car. My battery was dying for a while, and I never made the connection to my screen.

Today, I replaced the battery, and my screen came back to life with its old brightness. What's more, it even remembered the brightness setting that I had long ago. So, if your battery is old, you might try a new car battery to fix this.

The LCD's of laptops use the same CCFL to brighten the display. I won't if this is something that can be found on ebay? I'm surprised the little bits and pieces I can find on there sometimes.
