Audio Systems: Radio Display, pontiac grand prix, fm modulator

Question
Hi-

I have a factory Delco deck in my 2004 Pontiac Grand Prix. I was trying to remove the deck to install a remote turn on wire for my amplifier that I was trying to install. When I re installed the radio, the left side of the display was blank. It looked like a lightbulb had burnt out. It is a LCD, so I don't think it has bulbs. I read online about some possible solutions to problems like this, and determined that it could be a bad soldering job or some crossed wires inside the unit. I took it out once again and opened it up for a closer look. Everything was attached and no wires were crossed. When I put the unit back in again, the whole display was blank. The radio still works, the CD player works, and selected buttons on the deck work as well (EQ button, POWER button). Nothing can be seen on the screen. I have some steering wheel controls that I can use to change the station on the deck and the track on the CD's, and the controls for the volume on the steering wheel still work as well. I have tried wiggling some wire around and checking fuses with no luck.

Any help would be much appreciated.

Thanks
Zach

you are like the 10 person with this problem in this car people pull their radio to install a xm radio or fm modulator and lose the display lights  i need to get one of this radios on my hand because i have no idea what is causing this problem

so i am lost here  this is what i know  yes it is lcd display but it needs light behind to work and there is two small bulbs
maybe because the radio move hard the little light is going bad and needs to be replace
i also found out that there is a light/ ilumintion board outside the radio mount in to the dash there are some orange and orange black ,black and gray wires  it can be unplug or this unit is getting damage   i will buy a radio on ebay  can you email me a picture of your radio ?
