H03 Error & Disc Tray Error

I have tried everything as far as Resets per manual. I get an H03 error and the disc tray will not even open so that I may remove the disc. Do you have any suggestions other than my buying the service (repair) manual and supplements?

Most likely the tray for your player came out of aligment, this happens when someone pushes on the tray to close it, instead of using the "Open/Close" button, you need to take it to somebody to realign the disc tray.

My hk 30 player tray flashes (disc error) with every digital audio disc. help

Often times the tray and pickup lift assembly are related and there is a cam alignment. IF you pulled out with force the tray the alignment may have been upset to where the cam is not completing the lift of the Pickup and if not in the right position the laser will not be able to focus. The correct solution is at a Technicians bench where a new belt could be put in, lubrication that is required and some cleaning will be done.

Hi i have pyle pltsn74 is slip in a dvd disc an it was working when i ejected the disc it stayed in side an tray error came up on the screen i push the reset button an it did not work i carefully open it...

Disconnect the power to the unit; perhaps pulling the radio fuse out - in the fusebox. Then put the fuse back in because you've got to reset the error.

Xbox is fine but doesnt read the game disc

This is a common issue with the Xbox 360 console wherein it behaves as if no disc in the tray. This error is encountered due to a hardware failure in the system, probably the lens was not able to recognize the disc format since it was failing. You have to contact Microsoft Xbox support to have this fixed..

Samsung dvd tray won't! there is a disc in it and I can't get it to open...i got an error message that said "remove disc can't play"......but the tray won't open

On some disc players there will be a small hole in the face of the tray. This is a manual release. straighten out a paper clip and gently pusk it in the hole. The tray should come out enough so that you can pull it open by hand. Good Luck.

We have the RCA RS2767i Home Stereo with 5-disc changer and ipod dock. The CD Tray won't eject or shuffle...everything else works fine. It seems the disc tray isn't responding to anything. We read in the...

Let me respond with a possible solution although I'd bet that both of you already tried these.

The reason I checked into this is because I'm looking for a new mini system. I happen to be at Target and they only had 2 models - this one and a SONY. I certainly didn't want to buy the RCA given these problems, so I asked the salesperson, who seemed to have some knowlege.

As far as opening the tray on top, there is a button to push right under the tray. The button has an icon of a triangle on it. This seems to be somewhat of a standard icon for opening the tray or ejecting a CD (my car's CD has the same icon for ejecting a CD).

As far as only being able to get 3 CD's out, there is another button under the tray marked "disc skip". This rotates the tray. When you open the tray, you can only get to 3 of the CD's. When you push disk skip, it rotates the tray one position, so you can get the 4th one out. Another push and now you can get the 5th one.

Sometimes my CD changer doesn't shuffle the disks. If I only have 1 CD or DVD in it and push the tray open button, the disk stays in the unit and the tray revolves to an intermediate position. I push the button to put the tray back and try disc skip; that usually works.

If your problems are not solved per above, then I definitely do NOT want to get this.

Dvd do not loads

Our started doing the same thing about a week after the warranty ran out. It has to do with the alignment of the discs being loaded. here's a work-around that works for us:
Open the tray
Choose which disc you are going to watch and use the Change Disc button to push the selected disc to the back (ie, if you want to view Disc 1, discs 3 and 4 will be visible in the tray).
Look down the center holes of discs 3 and 4... manually move your tray left-or-right to align the holes with the tray.
Push the Direct Play button on the top right of the unit for your disc of choice (Disc 1 using the example above).

hope that helps... I've searched for a while and played around with the unit (with and without the cover on) trying to figure out a way to re-align the tray, but no luck.

Toshiba sd-4205 5-dvd carousel changer declares mecha error during startup, will not eject tray.

This may not work for everyone, but.....
I had the same problem with the Toshiba SD-3205. After unplugging, trying button combos, etc, nothing worked. I could here a slight whine inside the machine, and then again...."MECHA ERROR".
I turned the unit on its side to see if there was a manual tray button on the bottom. Nothing. Then just to try it, I turned the machine off and on again while on its side.
It started up, I heard a clatter, and then the display changed to "INSERT DISC". I placed it the right way up again and pressed "OPEN TRAY" and it worked!
My theroy: There was one DVD in the carousel, and I think last time the tray shut, it got wedged somehow and prevented the carousel from rotating. Turning the machine on its side and pressing "OPEN" is what dislodged the disk.

  1. Ensure the child lock feature is disabled.
  2. IMPORTANT: If necessary, consult the instruction manual for specific steps about how to disable the child lock feature.
  3. Attempt to open the disc tray.
  4. If the issue is not resolved, turn off the DVD player.
  5. Unplug the power cord from the electrical outlet for 30 seconds.
  6. Plug the power cord back into the electrical outlet.
  7. Attempt to open the disc tray.
  8. If the disc tray still does not open, simultaneously press the POWER+STOP+EJECT buttons; this will sometimes cause the disc tray to open.
If the issue is still unresolved, service may be required. The Sony® eService Web site at can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer.
