Hello, my babolat 4002 stringing machine is not working - the screen is all wavy and none of the buttons are responding. I'm fairly certain I am in need of a new circuit board (having taken the current one out it was installed in 1997) but I'm not finding anywhere that has them. Anyone know of a company/person/place that I could maybe find one? I really would like to repair the machine as we have had it for over 10 years without any problems and its a lovely machine. Thank you
