I have the same bad lcd panel on my car. Is there a way to tell the difference between the these,

Non I-Drive
Business HU (Option 662)
Professional HU (Option 663)

Do the units in the links above in ebay auctions work for both business and professional head units?

Isn't it labled on the front.(upper left corner)
I believe the US only has the Pro Radio.
They only time the business radio is mentioned here
is when its a Non Us poster.

pictures of the business radio in entry 1 and as you can see its labeled
and has less selection buttons and a different button layout.

If you buy a radio of ebay it needs to be programmed for the sound system
and options on your car. There are big threads already explaining this.
Also there are variations on the pro radio.

Job well done. Smash that appreciate button for BeakerBoy.

Wellps, I did mine and it seemed easy and straightforward, did everything the instructions said however the end result seems to be inverted quadrants.
My guess is one of the connections is backwards but want to make sure it's not a faulty LCD before I pull the unit apart again. Any thoughts?

You didn't transfer the orange plastic "spread plate" that is behind the old LCD display to the new display. The orange plate is what dissipates the lights from the LEDs. There is a post here showing the orange piece removed but where a little of it stuck to the LCD. Mine was not stuck at all.
Thanks for the great DIY! Very easy (if you have soldering tools and skills).

I think one of the ribbon cables is not fully seated. I'm guessing it's one of the two from the LCD display, but it could also be the one that connects the faceplate to the box. I would reseat all three. Remember the little black tabs on either side of each LCD plug pull out / down, in the same direction the ribbon cable goes out of the plug.
Thanks for the great DIY, I followed it this morning.

i did the pixel repair on my e39, but this looks harder and i don't really want to do it.

is there anybody that sells one fixed already that i can just swap in?

[ctuna]

If you swap radio's there is about a 98 percent chance you
will get a radio that is not programmed for the sound system
and option in your car . Better to send the exitsting one to
someone that will do the Pixel repair and send it back.
Be sure to write down your Serial number if you send it in
so you get the same on back.
Getting a new one programmed can be a more expensive and
convoluted At least the above is the case for all cars past 2005.

[tnord]

hmmm....thanks for the tip.

i'm going to call bavsound on monday and see if they can help me out. i'll do it myself if i have to, but i'd prefer not to.

[ctuna]

There are services on ebay that do it for 150 which is 50 bucks
more than the kit.

Sorry to resurrect an old post, but I have the same problem. Did you ever find out what it was?

[PIXLFIX]

Just in case - video of the repair:

[Nicker]

PIXLFIX, thank you for your video. Going to DIY. Do you still sell the replacement LED? if so please let me know how I can purchase one from you.

Thanks

Hi!

I have done all the procedure and I get this display (background is too orange, it should be more black)

https://ibb.co/nzSJ1V



What could I have done wrong?

I am 99% sure that the orange background is mounted in the right direction, the only thing I noticed is that this orange paper was a little glued to the old LCD. Perhaps I should have mounted it more close (I mounted it on the white support, but it should all close together) or glued it?

[AOrtiz135i]

did someone use the air condition vents to flow cold air to stereo and fix the problem? anyone?

That looks good to me, but I can't even remember what it's supposed to look like. My first thought was your LCD's working really well and is just that bright?

This is actually a good idea.

I had the problem a few posts back where the second and third quadrants were blinking solid orange while the other quadrants were black. I actually returned the screen and put the old one back. I can barely see the quadrants flashing so they're still there. Maybe I had the iron on the board for too long, I don't know, but now I'm facing another problem. If I have the radio on, the presets will cycle through them in 2-3 second intervals. If a CD, same thing, but tracks. Hot or cold, it's totally random. I don't know if it's the head unit itself or the steering wheel button.

[NCSUPack24]

Does anyone have a current source for these screens? It seems like all of the vendors mentioned in previous threads have dried up and the only ones I see on eBay are really expensive...

[austin.tillison]

bump. I'm having trouble finding a company I can ship my radio to, have it repaired professionally, and then have it shipped back to me. any options in 2020? thanks

If you send it in write your serial number down so you know you got the same one back.

[drawz]

It seems like the CD73 LCD module is no longer in production. Anyone have a source or advice on upgrading a 2006 model to an LCI radio?

*edit* found this info, but appreciate any other advice:

Best pixel is out of stock..

German audio tech charges $350 ! That's as much as a new radio, no ?

All other search results I found are out of business, stock, etc.

Any other current options ?

[drawz]

Looks like there may be some for the Alpine CD73 on aliexpress now.
