    I have the same problem. I've pulled the cover off, pulled out the CDs/DVDs, checked the connections, etc. I think the dang thing is dead. Second time with an Onkyo DVD player.

    Onkyo dv-cp704 will not turn on

  • maramouse Jan 05, 2008

    We've had the Onkyo DV-CP704 for about a year, and we did not have any problems until recently. The machine would not turn on, and even trying to reset it according to the manufacturer's directions would not get a response. We've tried to unplug the machine and then plug it back in a little while later, but the machine would still not respond. Some mornings after leaving the machine alone for many hours, it would turn itself on and open, but when I attempted to use the controls to test a DVD, we'd end up stuck in standby mode again. At this point we also have a DVD stuck in the machine and are about to take it back to the store to see what repairs or exchange options are available under the warranty. We've been on hold with Onkyo for more than 30 minutes today trying to find out how to at least get out the DVD that we need to return to the video rental store!

    Encountered the exact same problem much like maramouse describes and I too have had the player for almost a year. No problems until last night when the player became unresponsive and wouldn't initially turn on. Then turned on but wouldn't open. Would open but then wouldn't rotate. Wouldn't function from the remote either at times. Very sporadic. Unplugged it, left it for a while, plugged it back in. Still nothing. Left it overnight. Tried it this morning it starts working. Tested it with a DVD. It played for about 30 minutes and then it wouldn't respond to the remote or any amount of button pushing on the unit. Plugged it in, unplugged it a few times, pushed 'stop' and 'power' buttons at same time as someone else suggested and was finally able to get the bugger to open and give me my DVD back. Now of course I don't trust the thing. Has pretty much become an expensive door stop overnight. Very disappointing. Have never had issues with onkyo previously and was disturbed to see that others are experiencing the same issue pretty much at the same time. Not entirely certain what the desirable end game for this could be. Won't get any money back I'm sure and do I really want another one of these? Pay for a repair? I don't think so.

    Same problem as all others. Had the player for about a year and then the erractic behavior started. Wouldn't skip disks, wouldn't un-pause after pausing, gets stuck in standby mode and then magically in the morning turns on and opens up. Infuriating.

  • thepmpitstop Jan 30, 2009

    Wow, it sounds like Onkyo has a serious potential recall issue.

    I have the exact same problem with the player being stuck in stand by mode. I do not have a solution to the problem but, I was able to get my six discs about by unplugging the dvd player and waiting for the standby light to turn off. I then held the eject button on while I plugged the dvd player back in. Doing this allowed the player to turn on and open the table.

    Please email me at thepmpitstop@aol.com if you get a solution.

I was recently given a DV-CP704 with similar problems. I fixed my problem, well sort of - read on. I did not have a schematic so I decided to start by checking power supply voltages. I noticed a fluctuating voltage on the K0 pin. This is located on a connector on a circuit board under the disk drawer, and the connector services a cable harness coming from the front panel controls. NOTE: before removing or installing connections, I unplugged the player power cord first then plugged it back in. Not knowing where the voltage was originating from I decided to unplug the front panel connector. The voltage on the K0 pin of this circuit board stabalized at +5 volt and was not fluctuating. I traced out where this pin went to the front panel and among other places it went to the power on/off switch and the drawer open/close switch. I restored the front panel connection and while monitoring the voltage on K0 I noted that when I press either the power on/off button or the drawer open/close button this voltage would go low, not to zero but to some lower voltage but when I released the button the voltage would once again fluctuate. While watching the voltage, if I pressed the power on button when the voltage was near +5 volts, the unit would turn on and off. To me it seemed that this voltage should be stable at +5 volts with no button press and should go low only when there was a button press. Next I decided to unplug the harness that went to the drawer open/close circuit board. The voltage on K0 was still fluctuating so I restored this connection. Then I unplugged the harness that went to the power on/off circuit board. AHHHHH, the voltage on K0 was now steady. I removed this small power switch circuit board. Not much to it, some switches, capacitors, LED etc. I did not see any obvious issues with the circuit board. I decided that either the power switch or the small capacitor across the power switch contacts were breaking down causing the K0 voltage to fluctuate. I decide that the power switch was the easiest to remove so I unsoldered and removed it, plugged the board back in. Now I can power on and off by jumpering where the switch was. The K0 voltage is steady and all other buttons work properly. I assumed that the problem was the power switch. I checked the switch with a high impedance Fluke ohmmeter but to my supprise I did not see any problem with the switch. I decided to reinstall the power switch to recreate the problem however now everything is working normally. I can only assume that the heat I applied to the switch during unsoldering somehow fixed the switch by melting or burning away the problem. In my case it was the power switch however all of the tactile switches appear to be the same type so if there is an inherent problem with these switches, soldering or cleaning I would assume it could have been any one of them. If you want to give this a try, remove the cover, remove the 3 screws that secure the front bezel on the bottom of the player. There are two small clips that need to be lifted to release the front bezel so it can be removed from the player and flipped down to gain access to the back while it is still attached electrically. Attach your voltmeter negative lead to the main chassis (ground) and with the positive lead measure the voltage on the power switch pins. One pin is ground so it should read zero or close to it. The other is the K0 signal and it should be at +5 volts until the button is pressed. I don't know about any of the other buttons but they may also operate in a similar fashion. I hope this may help some of you.

My Onkyo DV-CP704 randomly stop playing, and switching DVD's


I recently had a similar problem with my Onkyo DV-CP706...the "DVD mechanism" part was bad. I sent the unit to the ABL Electronics in Michigan and they fixed it. They are an authorized Onkyo repair center. If you're still under warranty they'll fix it for free. My unit was not, but I opted to fix it rather than purchase a new one. They will clean your unit, inspect it for other potential problems, and it will come back to you better than it was when it was new from the store.

I had a similar problem with Onkyo DV-CP706--it would play CD's but wouldn't play or recognize DVD's. Looking at other people with Onkyo problems, it looks like this is the most common part to fail on their DVD players. I had mine fixed by an authorized Onkyo repair center, ABL Electronics, located in Michigan. They said a part called "DVD Mechanism" was bad. They replaced that part, cleaned the machine and ran diagnostic checks for other problems, then sent it back to me. It now works perfectly and makes less noise than it did when it was new. If your Onkyo unit is still under the limited warranty, they will fix it for you for free. Mine wasn't, so it ended up costing just a little less than buying a new machine, but I feel like it was worth it. You never know what you'll get with a new machine, especially if you buy online.

Onkyo DV-SP301 DVD player stuck in standy mode


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.

Shuts off after a loud sound


Hmmm...not sure but sounds like the vibration from the loud sound is causing the disk to jump. Not sure why that would power it off, but I think your thought to junk it sounds reasonable.
