You do not need to replace the Radio, but you need to replaced internally fuse in the Radio PC board

Here is a video of how I fixed mine. First step is to remove the radio, then follow the steps on the video. This fixed mine, so hopefully it will help you too. I am no expert however, so follow at your own risk.

Have a 2003 Accord EX-L with navi--same display problem just cropped up--though not as soon as some experienced it--does having navi complicate this repair or is it strictly a radio problem and navi is left out? Calling Honda tomorrow based on what I found in this forum (service bulletin on this problem issued by Honda) plus what a tech at our local Honda told us (Honda is well aware of this problem)--Hoping for a satisfactory outcome even if I am outside the 7 years extension given but am still within the mileage limitations--the car is now my brother in laws and he is not expecting much so am hoping he will be pleasantly surprised with a good answer from Honda tomorrow--Had this Honda serviced exclusively at this dealer for the time I had it and hope between that and good vibes from American Honda something can be done to repair this problem at little or no cost (good will)--Stay tuned!
