there is a guy in clinton township that has a business that might be able to help you, i dont want to break any forum rules so im not posting his website or phone but hi-tech, arcade, repair, clinton twp mi in google is a great place to start.
my friend and i went down there around the end of november and picked up a working astroids from him and he repairs tons of monitors and boards. I met him once, he seemed to know his stuff. i know there are guys on here from clinton twp that my have dealt with him more than me but thats where i would start.
