    The LCD you mention, is it the 5 inch one? That's what's on the R2. And where the HDMI cable attaches to the back of the LCD, is it directly attached? Or is there another part? Like an "L" connector? The HDMI cable has a female end that attaches to the LCD and a male end that attaches to the Pi. If it's an additional piece on the LCD I'm wondering if that somehow came loose.

    Good point on the HDMI.. the C2 does not use HDMI for the LCD. Check those connectors. The smaller one only has a ribbon cable back to the pi I/o ports.

    If you can get to the back of yours you can confirm the brand and model. The ones I linked for the C2 are an exact match ... If I had an R2 to compare to I match the larger one... Sadly nope:)

    You might just want to start by refreshing your SD card image because it is starting to smell ... Fishy

    Those problems might be related if the pi image is screwed up

    So this is part of the issue for sure! It was crooked, tried to fit my big ass finger in there to get it back in place and it fell out. Hopefully they will be able to tell me how to access it so I can put it back together. I tried taking out all the screws and pulling off the front bezel but I can't figure out how to detach the bottom from the printer. I got the top and sides but didn't want to break it so stopped.

    On the C2 the bottom part is held on with just two longer tabs (so if you pull up after popping the top out it will come out).
    Sadly I have no R2 to experiment with, but hopefully their tier-2 support folks can guide you on this.

    Another guy said they made him send his whole machine back because the screen replacement on the R2 is too tricky.... If this is the case it would be the second time sending it back...

    I have a hard time believing that it is "too tricky" unless those doors are held on by Magic Screws.
    But -- I can't say :)

    It is slightly harder than the C2 (which is a 5 minute job) but "too tricky"?

    However, your call :) You can either swap printers or do the fix.
    At this stage I would be concerned about shipment damage... they seem to be getting a lot of that.

    Yup I agree! If rather try to swap it out. But I'm not sure the screen is bad. The HDMI adapter was loose. So when I unplugged the HDMI from the screen and tried to plug it back in the adapter fell out. Isn't there a ribbon cable display port too?
