Question about Pioneer DV-C503 Multi-disc DVD Player

1 Answer

No sound playing DVDs

Hi, my DV-C503 has been working fine for many years, then inexplicably would not play sound for DVDs. I was using the optical Digital out connection, and swapped to the RCA plugs. That worked for a couple of weeks, now I don't get any sound at all. Any ideas of what I can try??

Re: No sound playing DVDs

Is it connected to 5.1 amp??.The first thing to try is to go to set up menu and change the audio o/p to pcm track.See if this works.What has more than likely happened is unit is set to dolby digital and should be on pcm track instead.If this doesnt work more than likely fault in unit but have seen very few audio problems with dvds.

Pioneer model # DV-c503 will play DVD but does not play CD's anymore.

The problem could be dirt on the surface of the lens.
Use a dry cotton bud to clean the surface of the lens, this you have to do gently because the lens is fragile.
If otherwise you have to change the lens.
Try websites, to buy parts for replacement..

My Sony DVP-NS57P dvd-cd player stopped playing dvds (haven't tried playing a CD). It displays ''Cannot play this disc''. When it first did this, I unplugged it and cleaned the disc and then it played but...

The messagin indicates that the unit recognizes the a DVD is present. Since it goes that far, it suggests that the information read from the disc is wrong. A dirty lens can cause this. Use a cotton swab as Welcomjee suggested dampened with alcohol. If that does not resolve the problem but a CD will play, then the optics are failing and need to be replaced.

Given the cost of replacement optics for your unit, if the optics are bad, replace the unit.

Hi camonk2004,

It's interesting that your DVD player was purchased in Russia but plays Region 1 DVDs. Region 1 is North America. Does your Player also play Russian DVDs (region 5)? If so, then it has probably been modified to play DVDs from multiple regions.

Check the back side of the DVD player - the rear panel should have a Region number on it. If the region number is 1, then try playing a Region 5 DVD. If it reads the DVD, then the modification that was done in Russia will probably allow it to read any DVD. IF the Region 5 DVD won't play (or if it is ejected automatically), then your player's region control os still intact, and it will only play DVDs from the same region as the one listed on the rear panel of the player (or DVDs marked "ALL").

I hope this helps - please let me know if I can be of any further assistance.

Kind Regards,

No picture, only sounds when playing DVD


The issue might be that you could be missing some codes to play the dvds.

First i want to uninstall all the codecs from the control panel - add/remove programs.

Then download the latest vesion of klite codec pack with the player.

The link is :

Install this by selecting "lots of stuff" with the player.

Then play your DVD, it will work fine.

Good Luck.

Live, Love, Laugh.

Movie Freezing

Sounds like youe unit is getting tired my freind. they dont make em like they used to. The unit most likly needs a tracking or focus servo alighnment, but to put it on a bench, and have a tech adjust the alighnments, will most likly exceed the cost of a new unit. The laser could also be getting weak, and the replacement optical assemblies for this unit alone cost about 60 bucks. Then you have labor and alighnment cost, as you don't just throw in an optical pickup assembly and it works. Good Luck Please, do not forget to rate this thread.
