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.
