Problem with CD deck

The other day I got in my car after work and for some reason the alarm went off when i opened the door. I dont know why, cuz i had to unlock it with keyless entry to open the door. So, out of laziness i just started the car. Now the CD deck displays weird numbers or just random blocks in the LED lights. It doesn't stay like that all the time, only when i turn on the cd deck or change tracks... but it goes back to normal after a little bit. Anyone have any suggestions on how to fix this problem?

Well... it seems the cd deck is working fine. thanks for all the responses.:thumbdn:

glad to see you got it working. :thumbup:
