sonyslave Posted May 12 Share Posted May 12 2003 R50 with OEM 6 disc changer and cassette player/radio would not power on. Pulled the radio fuse (fusebox on left side of steering wheel), still good, reinstalled fuse. Turn on key, radio still won't power up. Pulled the 'amp' fuse (fusebox on left side of steering wheel), was still good, upon reinstallation of amp fuse the 6 disc changer start cycling through 6 disc holders -even with the key off(well, ...90% sure the key was off) Turned on key and the radio powered up. No idea why, but radio works again (cd died ages ago, probably laser or laser transport is broken) Link to comment Share on other sites More sharing options...
EricCR Posted May 12 Share Posted May 12 Not sure what the question is, but yeah, the amp fuse is confusingly the one that controls power to the stereo. Back when I had it, I had to pull that fuse sometimes after I modded the cassette player with an AUX input. The cassette deck "thought" there was a cassette stuck in it at random times which necessitated the good old fuse reset. My guess is that your amp fuse was loose or is glitchy or something else in the fuse box is wrong (corrosion, loose wire, bent tabs). Link to comment Share on other sites More sharing options...
sonyslave Posted May 12 Author Share Posted May 12 Yeah, strange that pulling and reinserting the fuse fixed it. Maybe something loose in the fuse box, though everything is stock and the vehicle is stored in a dry environment. 22 years old, so odd things can happen....

Slartibartfast Posted May 13 Share Posted May 13 I remember my dad's '03 doing something similar. Pulling a fuse (don't remember which one, this was over a decade ago) and putting it back brought it around temporarily, until it crapped out again. I think replacing the head unit was what got it in the end. I would try unplugging the CD changer, especially if it's dead anyway. See if that clears up the issue with the head unit. Maybe the changer was locked up, and the head unit was waiting for some signal from it? The '03 service manual should offer some system troubleshooting, and at least tell you what all is wired to the amplifier fuse, which might offer some hints.

sonyslave Posted May 13 Author Share Posted May 13 (edited) Will try that should the unit fail to power up again! Disconnecting the CD unit could save the radio... Just fyi, in my case the entire radio/cd/cassette seemed to be not be getting any power, display would remain off when hitting the power button.
