eclipse head unit

hello out there, i'm just wondering if anyone know if there is a special way to turn on an eclipse 8051 head unit. i had got it from a guy who said that i did not have to worry about a security code or anything. so when i hooked up the unit, the knob lights had a nice glow. but the screen in the middle never lit up. i was able to hit the eject button and open the motorized face and insert a cd.  i looked through the holes on top of the unit and saw that the cd was spinning. but i could not figure out how to operate it because the screen in the center is not coming on and i don't have a manual. every button on the face had beeped when pushed except the "custom" button. i did hear feedback through my subs and at one time i could of sworn i heard "hiss" from my mids and hi's. could someone please help me with some operating instructions? thank you. merl

THANKS. YEAH, I JUST NOW READ THE OTHER ECLIPSE REPLIES ON THE OTHER PAGES. THANK YOU.

actually it still had its rca's on it. 2 "line-out"'s and a nonfader. i spoke to an eclipse tech from the 800 number. he said there should been a silver box attached to some cable. he told me the first time that the silver box was for the lights that were missing in the center screen of the unit. i called again and asked what was the orange illumination wire for and the tech said "that's for your backlight." and i said, "for the light in your car?"  "no, for the unit." and i had told him the tech i spoke to there earlier was saying that the silver box was illumination. he then said, "that was me!" so i got confused. somehow i requested to get repaired. i will tho, give the serial number to them and see if it's a lost cause. thanks guys@12v!
