Strange edge effects in konica minolta dynax 5d

[unageo]

Hello All,

I recently inherited a dynax 5d from a friend. He had not used it in a while and when I take pictures I get 3 very bright spots at the top of the picture. The severity of the brightness increases with shutter speed (longer exposure increases severity) and higher iso. I am completely new to photography. The problem goes away if I use continuous advance and take many pictures at once. The first photo has the problem but the subsequent photos do not have the bright spots. I attached a picture to illustrate this, I know its blurry but I wanted the 3 spots to be really clear. I apologize if this is obvious but most searches I conducted led me to "dark spots." Thanks in advance!

That is the sample image, the spots always appear in the exact same places.
