Anyone know for sure if the Stern displays use common anode or common cathode modules?
Anyone know where to get them in blue?

I started a new thread to discuss finding this part. Please look here for updates on my search.... https://pinside.com/pinball/forum/topic/wtb-stern-low-voltage-led-dmd-parts
Quoted from Gibo:I am on the hunt for them too,not common and what I have found have been very expensive,works out cheaper to get an after market display
Yea, the public pricing I found on these is VERY high. Agree that it may not be cost effective but I'm going to give it a good search.

I have 2 Stern red LED displays. One I bought used had a single line out and when I plugged it back in to test it, the line was working! I think that points to a bad solder joint on the board or a bad connection in one of the LED modules. I was looking for blue LED modules to replace all the red ones on the spare board but could never find a cost effective source for them.
If someone gets a confirmed correct part for these boards, please post the part number and source!
I just ordered some of the parts SaminVA posted above, I will let post back once I get it installed to let you know if it works and how well the color/brightness matches etc.

So I received the LED modules from eBay and have the following update:
1) The Sterm LED DMD uses Common Anode 8 X 8 1.9mm modules
2) The LEDs from that seller match well from a black background and size perspective but the LED color or brightness is off (see picture)
I am going to contact the seller through eBay to see if they have other colors or brightness.
Yea, the part number is visible on the modules on the bottom row of the Stern display. Mine has 2 rows of numbers:
LA-078811SE1WB

Quoted from DrMark12PA:Their warranty is 9 months per Stern.
The fact that their is a thread on this and as many people have noted this recurrent issue (whether is was replaced by Stern or people out of warranty are stuck either with a crap display and have to pay >$200 to replace), there is a known issue with this part.
I just talked to tech support at Stern and they are considering doing an exchange program for out of warranty DMD for possibly a different DMD though this has not been implemented as of yet. So, suffice it to say, Stern is aware this is a known issue. Tech support did mention the block is quite cheap as far as parts go ($10) but the labor is the issue because it's intricate soldering so if you send in for repair you are looking at $150 by the time you have it shipped to and back. A new DMD is $200.
Did they happen to give you the Stern part number for the LED block? Will they sell just that part so we can have color matched replacement parts?
Yea, I've replaced one module for the test above https://pinside.com/pinball/forum/topic/sterns-red-led-dmd-anyone-have-issues/page/2#post-1708231 I wouldn't want to do it without a real desoldering tool like the Hakko 808. The traces and pads are TINY! You need a light touch and a fine tipped soldering iron to solder the new module in place too....

If you feel like swapping the LED module, the Stern Part Number can be found here: https://pinside.com/pinball/forum/topic/where-to-buy-stern-dmd-8x8-block-for-acdc-display#post-1777579
You need to replace the block that has the dim LED in the column from your picture.

Quoted from ita47:Needless to say I wasn't real impressed with Stern on this one.
Geeze.... you think they could clean the flux off the board at least...
Quoted from ita47:Trent said that the repaired one will likely outlast a new one because of all the problems with the new ones.
Not sure what logic Trent is using here. The remaining LED blocks are still the same manufacture run as the one that failed. Could be that, like Scott suggested, that the C16 replacement is a different component that will help avoid the issue in the future.
ita47 - can you post the value of the capacitor at C16 on your display?
