Hi, hope someone can help me with my Barco Graphics 800. I removed the green tube to clean behind the glass because of fungus and reinstalled everything and now it wont start. It will power on but will not project anything, and I am getting a scan fail. Also the l.e.d. marked HTHD flickers on and off in sync with a clicking sound. Has anyone had this problem before? It should be an easy fix because I dont think I broke anything or shorted anything out. Any help would be greatly appreciated, Thanks, Chris.
