Help with zynthian build

I can’t seem to get my zynthian
To start up or boot up
And I am afraid to disassemble it and try again
In case I screw it even more than I all ready have
Any suggestions would be greatly appreciated
Or if any person would be help reassemble
So I can use it
Help!!!

Does it show anything on the screen? Like an Error.

Do you have a kit from the Zynthian Store? If so, which one? If not, what components do you have?

Which image did you download to put on the micro SDCard?

What’s the size of the micro SD card you used? I used a 512 GB card, and nothing worked. Then I remembered running into the same problem on my Emulation Station: it wouldn’t run from any SD card larger than 32 GB. Apart from that, it’s wise to pick a fast (v30) card. It will speed up your Zynthian quite a bit.
