Radio LCD/LED All On Problem?
 

My RX-8's radio LCD/LED (?) started doing this occasionally:

I always see the "mazda RX-8" initial display, and then usually it works fine for a few seconds. Then if the problem shows up, it goes "all on" like the picture. After a while it sometimes goes back to normal.

Has anyone:

1. Had this happen to your RX-8?

2. Figured out what triggers it?

3. Know how to get it fixed?

My RX-8 is still under warrantee so I think I can get it fixed at the dealer. I'm a little worried that I won't be able to reproduce it at the dealer though, and it's a bit of a drive to get there. Any hints/suggestions would be greatly appreciated.

Since I relocated the stock stereo, I had this problem a couple times. I replaced all the connectors and soldered/heat shrunk the connections.

Long story short, it is probably an issue with a wire between your head unit and the LCD. I wish I could be more help.

Thanks Slavearm!

I've been watching it a bit more, and it seems to happen more often when there is a lot of electrical load.

For example, it's less likely to happen if I start the car and (1) don't have my foot on the brake, (2) have the A/C turned off, (3) don't shift into reverse right away, (4) don't have the seat warmers on, and (5) leave the headlights off.

On the other hand, if I don't wait a few moments before hitting the brake, putting the transmission into reverse, while backing out using the electric power steering--then it tends to happen.

So I'm wondering whether it's an early indicator of a weak battery?

On the other hand, I took it to the dealer today and it stayed broken long enough for them to see the problem. They said there was a circuit board that could crack, and have ordered a new part. It should arrive in about a week. I'll be sure to post the final outcome, but it might be a couple of weeks because I've scheduled for business travel a week from Monday.

The dealer first tried replacing the LCD display unit, but that didn't solve the problem. They ended up replacing the head unit for the problem to go away.

Hi, i have exact the same problem as you did. how much did the dealer charge you for replacing the head unit? what is it anyway? sorry i don't know much about cars... is it the circuit board? Thanks for your time
