Question about Panasonic SC-HT740 System

SA-HT670 please wait problem

Seems I did the same damage by accidentally bumping one of the trays while open and it being forced back. I tried to re-align the trays but I don't know what is 'right'. Spabella mentioned removing the side of the tray to align the trays. Can someone expand on this?

I've got the same problem. The Changer block or traverse mechanism is a big cog work. One thing changed and its toast (I THINK) The white nylon gears are set and they are dependent on some cue to be moved. The left side of the block can pop off after the white top is removed, The side goes in and out to change ... plastic tabs. I'm pulling my hair out.

I've autopsied one after I bought another. The new one did the same as the old one right off telling me it looks like the issue is in the control, possibly the disk reader mechanism, or a glitch in the communication with the main board its tethered to with the ribon cables.

I'm searching for a reset hack/trick/ whatever, to reset it to factory. The problem is a glitch in the software, I Think.

Anyone have a clue on this?

I read there is a small wheel on top of the white plastic disc cover(take the units top off to see what i'm talking about), which there is, and it is used to align. It is done by inserting it at the bottum of the unit located front left side(just turn the unit upside down, no need to remove anything), however u need an extension to get the wheel up in the unit. I dont know what to use, especially to keep some type of extension from twisting inside the wheel while it tries to turn the wheel mechinism

My system says INIT please wait and the cd/ dvd trays are out of line i tinkle a little with electronics and feel that if i knew a little more about this problem I can fix it myself,especially due to high...



  • First you to pull out the DVD tray assembly and check to make sure there is not anything that has broke inside there. Make sure nothing is blocking the trays from moving.
  • Now pull the side cover off. There is a spare gear on the top of the DVD tray assembly. You will take that and place it in the two holes at the bottom of the player. This will allow you to manually adjust the trays. If you don't have this gear you can align the tray manually but it has to be real perfect.

  • Hope this helps and thank you for using FixYa.

Regards, Tony

Hi my problem is with the dvd tray it does not open . it make a funny noise but it does not open thx


OK I fixed it. One of the CD's had gotten stuck between trays in the loader. I pulled out a few CD's by forcing open the trays gently. However even after removing as many cd's as possible one was still stuck. 1. Remove screws holding cover plate on in back and sides. 2. Remove cover. 3. Lift face plate latches and lift over top of unit. Remove serial cables from connectors on board. Take face plate and place aside. Remove screws from back of CD tray unit and bend back metal tab with flathead screwdriver. Lift CD unit up on one side so you can get your fingers up inside underneath and push stuck cd towards tray openings. You can gently force top few trays out. You may need to shake unit so that stuck cd reaches open end. Pull out CD. 4. Replace faceplate and connect serial cables. Plug in power cord, power on unit and make sure trays will eject normally. 5. Put it all back together!

Cd tray wont open


this problem is due to bad handling of cd tray... tray is not opening whether its motor is damaged or cd tray is resisted by something from opening.... i recomend that send your machine to the company for checking... dont try to solve it manually by opening it if you dont want to cry in the end... opening will void its warranty..

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.

My dvd/cd try does not open when i press the eject button say "locked"


That means your trays are on Child Lock (this is a safety feature to prevent any accidental opening or closing of disc trays by small children when listening to your favorite tracks.)
To solve this, simply switch off your radio to Standby and hold the power button...whilst holding the power button, press open on the tray that is locked....the system will display UNLOCKED on the display of your hi-fi.

That should be it. To lock the tray....repeat the same process on the particular tray u want locked.

Disk player door


You would need to disassemble the unit to take out both the CDs. Trying to force the disk out without opening the unit might damage it. If you are not comfortable with open it, please get someone who can actually do it for you. please revert back with the results.
