took the car to a installer they took out the radio and added some stuff so they could hook up a couple of amps for subs n stuff.

anyway after they put it back in only half of the display is lite

they have more work to do next week and they said they'll fix it then......why or how did this happen

What is the year and trim line of your car? What kind of radio is it?

whoops........... its a 2000 se not the monsoon and no eq just your basic cd tape radio

Sounds like display bulbs may be burned out or loose. Need to open up the radio to check/replace them.

but it was working properly before?

I had two of them in my climate control burn out after I took the dashboard apart once.

how are they replaced

On my radio, you have to take it apart after you remove it from the car. Probably the same with yours.

thanks for the info. the shop just called and ther going to do it for free
