SL/R230: R230 Instrument Panel LCD DIY
Please post the exact measurements of the LCD next time you get them out.
I’m looking at the replacement options and there is nothing of the shelf at the moment.
kbob999 mention E class being the possible donor but the cluster looks totally different. I need to investigate little more though.




PS. I also have been looking closely at the two new modules I've just gotten and these seem to have a problem with the film on the back side, rather than the front. The ones I had previously been working with had the problem exclusively on the front side. I'm starting to think that the answer is to replace the film on both sides with one film rotated 90 degrees from the other.

I've screwed up a couple of panels. Currently my left one is only half functional because either the connector is not doing its job or I have damaged something. They are pretty delicate.
One other really important thing: if you look at some of the photos above you will see some where there is kind of a amoeba shapped blob. That is actually an issue with the liquid crystal layer and will not be fixed by changing the polarization layer.
I replaced my faded SL55 LCD panels with donor LCD's from a wrecked SL500. The LCD's are not available new to my knowledge, so used parts are the only way to go. In this case, the used LCD panels were only marginally better, so I am still searching for bright LCD's.

By the sounds of it, you do have a connection that works. Coding of the new screens is not required.
Keep us posted on the outcome.




If you plug in a cluster, the information will not match, and the mileage will read "------". This must be fixed by coding the cluster to the vehicle, which is dealer only.

The used instrument cluster was a little less (purchased from an auto wrecker) than the Chinese unit.
Hope this helps.

My poor little SL....
The simple solution??? Replace the screens with brand new ones - Minitools in Italy (back in business since spring 2021) supplied me 2 LCD screens which are apparently better engineered.The fit and function are perfect (even though they don't look identical to the original - hence improved?!) at a great price.They couriered them at reasonable cost and I installed them to great result. https://store.minitools.com/en/sepdi...-clusters.html
I just checked a pair of LCD displays including shipping to US would cost €189.50 or $219.68. Not cheap, but still lower than buying a used instrument cluster. I bookmarked this item and may order it sometime later.




The product and price you got from minitools is by far the best I have seen. GREAT FIND ! I ended up getting some displays from china for my SL55, but they were a least 50% more than minitools price and look the same.
If I still needed some, I would place my order today as there is no telling when they may be hard to get again and it seems very unlikely they will ever cost less.

Installed the two panels. Beautiful. Look super. Can even read them with sunglasses. Just what I needed.
Then the problem began. Hope someone can help me with this issue:
1. After five or ten minutes the left display went slightly dimmer and started flashing 3/sec. The right display lasted another five minutes, then went all white, then black. Turning ign off, then on made no difference.
2. Replaced them with the original dim units which actually were only a year old, but which worked fine, just dim. They now had this same fault, so the issue is not with the lcd panels, but the car system, or maybe the wire socket.
Does this fault make sense to anyone? Is there a computer reset to be done? I did not disconnect the batteries, so perhaps that was the cause.
Open to all suggestions. I'm stumped and stopped.
Thanks.
