The radio in my 2003 accord coupe shuts off and the backlight fades in and out. do I need a new radio or can this be repaired?

unfortunately the backlighting on these radios is not serviceable, you can attempt to have someone repair the radio, but better off getting a new factory one, wrecking yard one, or going with an aftermarket unit

If you're getting power to the CD player then there's power
to the radio. The antenna involves the grid on the rear window,
an antenna coil and cable to the radio. You can check the
grid for a break and if it's small you're auto parts store will
have a repair kit. My 05 Accord rear window defogger did
not work and it took Honda 2 attempts to repair it. Other
than checking the grid I would bring it to the dealer.

The 2003 - 2005 Accord CD/Radio unit is prone to display failure. Honda had issued a TSB some years back but you may be beyond the warranty period. We repair this display issue. Check it out: www.autoclockrepair.com

There is a factory default with the radio circuit board in radios installed in 2003-2004 Honda Accords. Honda will replace or repair the radio free of charge on and extended warranty. The radio will eventually fail for good. I know, as the one in my 2004 Accord failed in March of this year. My Honda dealer replaced the radio with a reconditioned unit absolutely free. Contact you local Honda dealer.

I WOULD LET THE DEALERSHIP REPLACE RADIO BECAUSE BY IT BEING PART OF THEFT SECURITY SYSTEM.IF YOU DO IT YOUR SELF YOU PROBABLY GOING TO HAVE NO START PROBLEMS.THE PCM WILL GO IN THEFT MODE THINKING SOMEBODY TRYING TO STEAL RADIO OR CAR.IF DEALERSHIP FIX THEY PUT IN NEW RADIO THEN REPROGRAM IT.

My 2003 Accord LX does the same thing. It started about 6mo ago and it becomes more and more often. I just went outside to kick the off from inside the wheel wells and the stereo came on.

if the battery you installed was charged and was up to at least 12 volts,it should have turn the engine over quickly,since you still had to jump a good battery to get started,you must have a starter dragging,you will need to change it

Look for radio anti-theft code in glovebox in packet with owner's manual. Also in some honda's it will be on a sticker under the ashtray.

Depends on how it's done. If you do it, it could be about $2500-$3000. you will have to pull all the necessary hardware, transmission, computer, wiring harness and other parts from a car that has a stick. And swap them over.

Unfortunatly the code is directly tied to the S/N of the radio. Without the serial there isn't much I can do for you. But If you are handy with a wrench and can remove the radio yourself, then I can more than likely get a code, but I too would need the S/N.

Hope this helps
