Question about Panasonic SC-HT740 System

1 Answer

Jammed cd drawer

I loaded 5 music cd's into my HT740 system changer, and it closed ine. However, when I went to play the first cd, it locked up and subsequentially shut down.I presume that the cd's have shifted (this happened before) and are now, in effect, "stacked", so that the drawer mechianism won't let the dawer come out. Short of taking the unit apart, how can I get the drawer open so that I can rearrange the cd's ?

Re: Jammed cd drawer

The best solution is to take off the top cover. It's easy to remove with, I believe, four screws. The carousel is located right underneath the cover, so all the CD's will be exposed. However, I don't think that this will solve the problem of not happening again, since this seems to be a problem with this particular model.

My RCA RTD 206 5 disc changer wont play DVD's. It stays on Disc 3 or just says close. I called the # in the manual foe help, but its no longer in service.

If it plays the same disc without issues, you have a mechanical(or the electronics powering the motors and such) problem. For more information, please visit my website at Thank you.

I am having problems with my SA-HT670 it is reading error code INIT and then WAIT. The 5 disc changer will no open and close properly

The CD loading mechanism is not resetting properly. When powered on, the entire mechanism goes through a startup alignment sequence. This is to be sure that the unit is in a known position and state. The init indication is for the "electonics" reset portion, the wait message should be present while you hear the mechanism move. The most common cause of this is a slipping belt or a jammed CD. Be cautious about trying to repair this yourself. It is easy to damage the gearing inside or to get it out of aligment. There is a good possibility that this can be repaired with either no parts or with a $3-$5 belt.

I do not know how to load my cd changer. it is supposed to hold 5 cds, but I can only load one at a time.

On the face of your player you should have a couple sets of buttons relating to advancing the cd in the player. One should be for advancing the next track on a given cd, often designated by a single arrow. The second is for advancing to the next cd and will be designated by a double arrow symbol.
While the drawer is open try press the the double arrow button. This should advance the player to the next empty position. If this fails you may want to try the other buttons as well.

SA-HT740 Broken gear

You probably can get the parts from Tritronics, but as far as I know, there aren't hard-copy manuals normally made for any of the newer products. The only paper available nowadays are the users manuals... The service manuals are on-line at Panasonic and available only to authorized repair centers. Sorry.

I'm curious - how in the heck did a gear break in the thing??? There's nothing strong enough in the drive system to do that (either the motors would sieze or belts slip).

DVD HO1 error, and tray is jammed - how do i change the mode to External Port (iPod)?

It means that there's a misaligned disk inside. You need to

1. Unplug it and shake it side-to-side.
2. Then turn it on and press the open/close.
3. If it doesn't open, goto step 1.
4. When it opens, get the disks out, use disk exchange to try to get them all out.
5. Turn it off, unplug it, shake it again and make sure that there isn't another loose disk, if there is, then open it and get it out.

This is a known flaw in certain Panasonic DVD changers. Good luck
