ONKYO DV-SP301 plays audio cd OK. DVD disc, says reading disc, then no disc message. Nothing in manual for this system under trouble shooting.

If you turn the remote over there is a tab at the top push that towards the bottom of the remote and pull up. Once you have the battery cover off replace batteries with two AAA batteries. Click below for a copy of the manual. The battery replacement is on page 9 of 40 in the adobe document.

Hi

Similar Issue happen to one of my client what we have done is putting the JPEG files into folders (Not Subfolder). It worked well however some JPEG images being skipped if the size is unusual. JPEG images will appear as tracks. Hope this will be helpful. If issue persist please post once more. Also let me know if WMA files are being played.

Good Luck

clean the laser using a lazer disc cleaner not only does the disck get dirty but the lazer too when its too dirty it wont read the disc -- disc error
heres a piture of one you get them from electronics shops

Could be dust on laser or track for the laser guide, as it moves back and forth, may also need lubrication....

hit the change mode button

Hi
I know the reply is a bit late but I had a similar problem.
The problem is with one IC close to where the motor wire are connected. This particular IC overheats and that was causing a malfuction. So I have installed a small heat sink and now all is well.
Hope this works for you too

All the best - Clayton

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hi

As per its user manual you cannot play back discs such as VCD (VIDEO CD) ,CD-R, CD-RW, CD-ROM, DVD-RAM, DVD-RW, etc., even though they may be labelled . Please refer to Onkyo DVC600 User Manual for more information.

Please do rate the solution as FixYa and revert for further assistance.

Thanks

Had an Onkyo DV-SP301 that would only intermittently come out of standby. Found faulty resistor R2 on the power supply board (board ORTP-865), it was nominally 5600 ohms, measured much higher. This after checking most p/s caps! R2 runs warm when unit is in standby, so you may want to replace with a higher power rated resistor. I used same rating but 10 k ohm instead, worked fine then.

please dont buy this
