A dedicated chess computer, Mephisto Munchen Lyon

[addi]

Hi,
I bought a couple a years ago a Mephisto Munchen Lyon dedicated chess computer from Germany. It worked well for a few months but then I stored it away for a few weeks and when I turned it back on it did not work anymore. It only shows the red on light when I turn it on. I live in Pasadena, CA, and was wondering whether you know anyone who could help repair an old Mephisto dedicated chess computer. Any advice would be much appreciated. Thank you.
