Saturn 3 motherboard replacement

[KenW]

Help.  Need a link to a video that shows how to replace the motherboard on my Saturn 3 ultra.

Can't seem to find anything about this anymore.

Thanks

I didn't find the video you requested but I would like to know where did you buy the Saturn 3 Ultra motherboard.
I just can't find it.
I damaged mine taking out the glue from the connectors to replace the LCD.
Thank you in advance.
