reparasjon markiser

Hi, I have a markise med sveiv on the balcony, but it looks like the vinsj/snekke is broken. Or maybe it just snapped out of position. It is not vertical anymore, it is almost horizontal (please see pictures attached). So, I cannot extend or close the markise. The sveiv is not usable anymore, as the vinsj/snekke is blocked and would not turn in either direction. Please let me know if it is possible to repair it? And if you can provide an estimate of the costs. Probably the vinsj/snekke needs to be replaced. Thank you in advance and have a good day!
