Issues with X-370S is it a dead light meter?

I think my minolta has been having some issues with it's light meter. When looking through the view finder, on manual it consistently tells me the image is underexposed, depicting a down arrow, even when the shutter speed is moved down to 1/1. On auto, the shutter is locked open for several seconds before closing.

Kinda frustrated because I am new to all manual shooting, and this is forcing my hand a little bit. Having to estimate the exposure needed is difficult with what little experience I have. Has anyone experienced this issue? Is this something that can be fixed?
