hello guys I am new to this forum and this is my first post. I had my avicn1 flex cable replaced 14 months ago by pioneer. A few days ago the screen stop coming on (lighting up). The screen is pitch black. My question is the bulb gone or is it the cable. One pioneer tech mentioned it might be the fluorescent bulb. If it is where is it located on the header display and of where can i get one. Apparently pioneer will not sell it to anyone. Please help.
