It dosent read the dvds that i put in it say loading then no disc

My onkyo DV BD-507 only play dvd disc, and dosent play blu-ray disc

This problem is normal and exists with many CD/DVD drives.
On some of the drives, if you put in blank discs and try to open the disc in My Computer or Windows Explorer, Windows displays no contents or a blank disc. Whereas on other drives, you get the error message that you mentioned about incorrect function.

What software are you using to burn CDs or DVDs? Are you able to burn CDs but not DVDs or you can't burn both the discs? Did you try a CDs with a different make/manufacturer? Some drives refuse on some disc makes. Try another disc and another writing speed, or try the lowest writing speed available with your software.

Hope that helps,

Most likely the DVD laser lens is dirty. Unplug the CH-DVD 300 from the wall outlet, wait 5 minutes, then remove the top cover. Next, remove the rectangular metal plate which covers the area where the CD or DVD disc would be when in the player's tray. Underneath the rectangular plate you should see two small lenses. Gently clean these lenses using ear swabs moistened with isopropyl alcohol. Reassemble the CH-DVD 300 in the reverse order that you disassembled it, plug it back into power, and now it should read your DVD discs just fine.

if it's a fat PS2 and
model SCPH 30001, SCPH 35001
(not including the models with an 'R' after the model #.

these models need the following to play DVDs:
- PS2 DVD remote with IR unit
- PS2 DVD disc player (sold with DVD remote w/ IR unit)
- PS2 memory card

you copied the DVD disc to the memory card. you used the memory card to play DVDs.

later models didn't need the memory card to play DVDs.

hope this helps :D

sounds like the blue ray lens fried, u should be able to find one on ebay or craigs list not hard to put in

You may have a bad laser. First, make sure the laser assy. travels back and forth easily, then make sure the table the disc sits on spins freely. If it still isn't reading, load a disc and immediatly flip it over to it's top and see if it works. Working or not, still a bad laser.

PS3 is The amazing device by sony but it has some common problems like disc read error, unreadable disc etc.... Good news is that these all problems can be repaired with the help of DIY Guides, one such guide available at PS3 Repair Blog

Check on sony.com for a service center in your area.

The optical lens is out of alignment. This is why it will read CDs which have much larger data pits that DVDs.

The unit should be able to read and playback CDs (both production and burned) and DVDs (both production and burned). If the optics are out of alignment and exceed their tolerances, the player will not read discs.

This is caused fromt he player being dropped or jarred.

This is not an easy fix for the home user. This is something that a qualified professional needs to correct.

upgrade the firmware on the product.
