Onkyo DR-C500 "Disk Err" - Whats the fix?
Hi:
This 5.1 receiver/dvd/cd (5 disk changer) player has developed a problem: displaying 'Disk Err' when changing to play a DVD or CD. Seems to be more temperamental with DVDs (happening about 80% of the time) and with CDs (about 20% of the time). Receiver is about 3 yrs old, and it occasionally did this when new, now it happens a lot. Can anyone relate with the fix is? or some things to check out? This appears to be a chronic problem with units of this type - Are there any 'official' ONKYO fixes? The laser diode and subsequent processing channels look OK - seems like its an alignment problem when the disk is lifted onto the spindle... Any help is greatly appreciated. Thanks John |

Thanks John It's a chronic problem. Read a bunch of people having problems with it not reading DVD/CDR reliably. Google - Onkyo DR-C500 disk error and read some for yourself. As far as a solution goes, there may not be one. You could contact Onkyo tech and see if there is. Yes, I found that even before I did the post. I figured by now the root cause would have been discovered and the 'universal' fix would be floating around. Perhaps the fix is to deep six the unit...lol If I were the owner, I'd be upset...$600 and about three years later its garbage...There ought to be a law...lol Thanks John |

Is that the one used in these units? Thanks John |

Can the firmware be upgraded in these things? John |

Can the firmware be upgraded in these things? John No upgrades for this model - I checked. Like I said, it's a pain to get into one of these. It's been a year at least since I've been into one. As best as I can recall and from looking at the service manual, you can't even SEE the pickup without a pretty major disassembly. There's a circuit board over the top of the mech, and the power supply at the rear needs to come out also. Huge PITA, courtesy of Philips. The thing is, they don't want these things worked on once they're out of warranty - we are just expected to replace it with another piece of crap so that we can continue to keep feeding the Chinese army. I'm going to try sending you via e-mail a couple graphics lifted from the service manual. Mark Z. |
