Question about Onkyo DV-CP702 DVD Player

Onkyo DV-CP702 will not load any disks!

Hey, Maybe one of you guys or gals can help me out. I have had this thing in the shop twice now for the same problem of disks not loading. 1st time they gave me a new player, 2nd time they sent it off and repaired it. Now I'm out of warranty and they want and arm and a leg to look at it. I told them they couldn't get it right the 1st time so I wasn't gonna pay for another guess at fixing the problem. So I load the disk and it starts to spin and then it just stops and says no disk. I removed the top to have a look and the darn thing starts playing. 5 minutes later its back to the same thing again. It just refuses to load. I noticed a loading mechanism that looked as if it could be adjusted or replaced. Any suggestions on this before it gets trashed. I hate to do it because its not even 2 yrs old yet. And by the way my 2 yr old is screaming for her disney movies! Thanks Will not load DVDs or CDs .. reads "LOADING" , then gives up and changes to the next disk and keeps going till eventually one disk says "NO PLAY" and hangs up. We have tried resetting by unpluging. We tried initililiazing as the manual suggested... but pressing the stop button while pressing the standby ON button gives no results. It doesn't seem to even try to intitialize.

HI,

Yes, it may be a mechanical misalignment. You may be able to find a way to readjust the tray, etc., but probably the focusing of the laser diode needs reset. For a dvd player this old, you are lucky to the extreme that it still works at all.

Any dvd player over two years of age that needs major repair should be replaced as the cost of repairs will be greater than the cost of a new set! Sad but true. You will not be able to get the focus adjustment done for less than $50!

So, my strong advice is to get a new dvd player.

FEW TROUBLESHOOTING STEPS YOU CAN TRY:

Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable.

Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word.
This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces.

You could try to clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try.

If you actually see dust on the lense, then its just that simple. clean, close, play.


It may also be worth your while to check on the small shafting that guides the carriage of the laser pickup. Dirt, grome, dust and solidified lubricant can cause stoppage of the carriage and the laser eye then fails to read the next track. Please refer to the image below.

There were a number of these that had similar problems that were fixed under warranty. If I remember correctly, there was an upgraded servo chip for these. If the shop was an authorized service center for Onkyo, they should have had the bulletin for this. The upgrade was based upon the serial number. Unfortunately, the chip replacement is not the easiest as the chip is a multi-pin surface mounted one. Can you post the serial number of your unit please? I'll research the bulletins for you.

    As I mentioned in my original posting, there were upgrades to the servo chip to address issues with the timing of the disc system. Essentially, teh discs would not spin up fast enough on occasion so they were mis-read and the message no-disc would be displayed. Please check out this upgrade. I worked for an authorized service center and saw many of these units. The exact symptom of sometimes working/sometimes not was common. Also, changing the positioning of the whole unit would allow the motor to be more efficient as there would be less drag on it thereby allowing the spin-up time to be shorter.

My onkyo dvd player is reading mechna err


This is usually caused by a broken tooth on one of the cam gears. While relatively inexpensive for the parts, the unit must be rebuilt in the correct order and alignment. This is not a DIY repair. It is possible that the unit is just confused and out of timing. Try unplugging it for 5-10 minutes. Plug it back in and see if it resets. While I doubt it will, it is worth a try. If not, then the unit should be serviced. Figure on $60-$75 for the repair.

I have an Onkyo DV-CP702 and it keeps saying I have a mechanical error. I thought a disc was stuck, so I followed your tips and took off the top and indeed, there were 2 discs stuck. I took them out, but...


The loading mechanism is out of timing and needs to be rebuilt. This is a fairly strightforward procedure if you have the manual as there is a sequence and alignment procedure for this. No parts are required in most cases. This unit should go to a service station. If you attempt this and are not aligned correctly, it is possible to damage the optics assembly.

DVDs presumed stuck and the player won't eject


Hi, If you feel comfortable opening the unit, then you may remove the top cover normally held by 2 - 4 screws. The tray should be visible and most units have a locking bar right at the center to hold the discs down. Removing this (2 screws normally, 1 at each end of the bar) would expose fully the tray with the 2 discs on top. Remove the discs and put the locking bar back with the screws. You can test the unit without the top cover. Please be reminded about safety precaution when working with active/live units and laser equipment. Power it up and check if the "mech err" still shows. If not you're set to cover it up, otherwise, your probably better off seeking the services of a qualified technician. This is a generic method which normally should apply to most CD/DVD units. Good luck and kind regards.
