The voltage regulator -- failed? Happens. I had the same problem.

Take it to a repair shop or get the right part and replace it yourself.

I'm confused by both the original post, and the answer. There really isn't a question in the OP, just a statement... actually a description of a part. And then there is an answer... based on an assumption. How exactly can anyone help with this? Emtdan... I see that you are fairly new here. When someone posts an incomplete question we often try to encourage a more detailed post so that others can join in. I am not criticizing either of you, just saying that better answers are available with better questions.
