Had this on my system and took it apart to find when you put disc in it is not spinning up to read disc !!! possible drive issue

using red yellow cable connected to aux on home dm3 connect other end to audio out on tv

Might be cheaper to pick-up a sub-woofer and a set of speakers at the local store. I checked e-bay..no luck, and it doesn't look like Panasonic will sell separates. It will be easy to get a color match.

It is always wise to tell us if this is new equipment or a spontaneous failure on previously functioning equipment. I'm guessing this the former.

For starters you could look at the manual.

Its physical orientation is wrong, possibly upside down.

Hi,

As you have already Unplugged the Unit ( It should be more than 60 Minutes, as this would Reset the processor ), and it did not help, so you are only Left with one trick which is Explained as follows :-

This errors usually happens because the spindle(The thing that spins the DVD), isn't moving properly. You can try this to see if that will fix it:

1) Eject the tray, and unplug the unit with the tray out
2) Remove the case
3) Locate the spindle, and spin it gently a few times
4) Put the cover back on and see if that fixes the issue

If that doesn't fix it, then the spindle will need to be replaced.

Note - There are some people saying it is the optics ( On many Search Engines and Forums ). But it rarely turns out to be the optics when that error message is shown. If you turn the DVD player on, and you can hear the disc spinning, then that would mean that the spindle is working. But if it doesn't spin up, then it might just need a little nudge.

As far as opening it, the only tricks that I can provide are general tricks to get any tight screw out. That would be to try putting a small drop of WD40 on there(Don't get it anywhere else).

Then put a screwdriver in, and tap it gently with another screwdriver handle to try and loosen it up a but. Then try opening it. Also, make sure you are using a screwdriver that is a good fit with the screw, or you will only make it more difficult to get it open.

If it's the spindle motor, then I know the part might cost between 30 - 50. Considering that labor will add to that cost, it might not be worth it. If it were me, I would replace the whole thing rather than take it to the repair shop.

If you still Wish, i could try to Search the Spindle Motor for you as i know a guy who used to sell this Motor for $42 .

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

The nearest you will get is the service manual. Dowmload the service manual and follow the dissasambly and reassambly instructions to the letter, otherwise it will not work correctly and the timing will be out. https://elektrotanya.com/panasonic_sa-ak20.pdf/download.html

Try disconnecting all of the speakers except the left and right main speakers. If it works, check the wiring at the back of each speaker to make sure there aren't any shorts between the terminals. Better yet, just inspect the terminals both at the audio unit and the backs of the speakers. Stray strands of wire reaching across to the other terminal or exposed wire on the other side are a common problem. If you have that all cleaned up and still have the error, you may have shorted transistors in the output amp of one of the channels, very likely the subwoofer. This may be caused by shorted speaker wiring, or the amp may have failed on its own. In either case, you would have to replace both of the output transistors for that channel (they may be built into a power amp module, in which case the module must be replaced). This requires soldering skill, and the knowledge to identify the transistors and check them with an ohmmeter. Most of the time, it's a basic job for any skilled electronic technician. (I did run into one model that would have required two days of disassembly labor just to get at the failed transistors - I told the customer that wasn't designed for service and he would be better off buying something different to replace it.)

If your Panasonic DVD/CD player is not reading CDs and is making a grinding noise, there could be several issues at play. Keep in mind that specific troubleshooting steps may vary based on the exact model of your DVD/CD player. However, here are some general suggestions:

1. Cleaning the Optical Lens: Over time, the optical lens inside the DVD/CD player can accumulate dust and debris, leading to reading issues. You can try using a CD/DVD lens cleaning kit to clean the lens. Follow the instructions provided with the cleaning kit.
2. Check the Disc: Ensure that the discs you are using are clean and free from scratches. Even new CDs can have manufacturing defects. Try using different CDs to see if the issue persists.
3. Inspect the Loading Mechanism: The grinding noise you're hearing could be related to a problem with the loading mechanism. Open the disc tray and visually inspect for any obstructions or foreign objects that may be hindering the movement of the tray.
4. Reset the Player: Turn off the DVD/CD player and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on. This can sometimes resolve temporary issues.
5. Firmware Update: Check if there are any firmware updates available for your DVD/CD player. Visit the Panasonic website, enter your model number, and look for firmware updates and instructions on how to perform them.
6. Professional Inspection: If the issue persists after trying the above steps, it may be necessary to seek professional assistance. There could be a mechanical problem with the internal components of the player that requires specialized attention.

If you are unable to find the exact manual for your specific model online, you may want to contact Panasonic customer support directly. They can provide you with model-specific advice and may have access to manuals or troubleshooting guides for your particular DVD/CD player.
