hello!
i have somewhat of a solution to this problem. my expression was doing the same exact thing, just like the video and thinking about the fact that i might have to buy another one again, i decided to open it and this is what i found.
when you pull the blade housing to the left (when the machine is off) you will see a red button all the way on the inside of the right. if youve searched the internet, you probably found that this is the reset button. once the machine turns on and makes some start-up noise for a second or two, the blade housing moves to the right until it hits the reset button and stops moving. this button is broken. that is why the blade housing keep moving to the right and makes that horrible noise.
my husband was able to fix this for me but you basically have to remove the the right side panel to get to the problem. i actually removed the bottom panel first, unpluged all the wires (theres no way to get them mixed up since they are all different connectors) and used a screw drive to 'unhook' the gray cap that is covering the screws on the right side. once you have the right panel removed, you can put the bottom panel back on (make sure you replace all the connectors)
when you have the right side panel removed, it will look like

if you look at the next picture, the black 'button' with the black and red wires running out of it, is the reason why its not working correctly. it should look like the picture below but mines was completely disconnected.
if you can get two pliers, or one socket and one plier to unscrew and remove the actual red button, and glue it back you can get the machine running again. crazy glue is probably not the best type of adhesive since the reason the button broke was because of stress of the housing, you will need something that bonds and flexs as well.
however, my husband put too much glue and made the button stuck and not move, so he replace it with a completely different button altogether. i know this is not the best advice on exactly how to fix your cricut but i really hope it helps you. if you have any questions, my husband would be happy to assist in explaining. :)
