Display test appears to fail... but hasn't failed

Step 6 - Display test in Preflight check on Page 6 of 25 of the SL1 Assembly Instructions show a black and orange Prusa Research photo.

I thought my UV leds must have failed as mine looked like this photo but without the orange. Ie I could see the LCD was working but I had the wrong background colour.

As you can see from this photo, I was looking through the orange cover. There doesn't appear to be any light coming from under the LCD, but at least text can be made out;

Prusa Display Test Error

After reseating the connectors, I realised the UV leds and LCD were fine when I could see reflected UV light on the inside of the metal cover (I gave up screwing it on and off whilst troubleshooting errors).

Perhaps I had the orange cover up?

Here's that photo. As you can see, I was looking through the orange cover.

You should be looking through the orange cover! Never look at UV LED's directly!

 

You should be seeing the below through the orange cover. If you are not contact support via chat.

Sorry Olef

I mangled my edit. I was looking through the orange cover. I'm unable to correct my original post, but I posted a reply saying "

My point is that the LCD with the UV leds turned on looks like the photo I posted above, not like the photo in your reply or the manual. I thought my UV leds were broken, because the photo in the manual is misleading. They weren't broken; I've printed lots of prints now.

The edit time on posts is way too short on this forum certainly.

How strange as you cannot see the test but can still print. Whichever way you can print which is the desired result, and I've now learned something new about the SL1. Only got mine a few days ago so baby steps at the moment. Hope you are enjoying yours!
