20 Most Recent Panasonic SC-PT1050 System Questions & Answers

I have the same exact problem. Turns out my toddler has stuck a piece of paper in the tray, so the tray was just stuck. I just undo the four screws on the side and 3 in the back, lifted up the top cover, remove the paper causing the jam, put everything back together. Problem solved. Saved $140 from having to sent it to Panasonic

I had the same problem. I had to take it in and have the caruousel realined.

That sounds like defective internal wiring or a loose connection on the amplifier PCB. If you just purchased this audio system. It should still be under warranty for a defect.

Hi look for a sub level control in the set up and turn it up,this may give it a kick start,also is ther a volume control on the sub? if so turn it up half way.

HOPE THIS HELPS.

It is possible, but very rare that I have seen this, the unit's AC plug is not making good contact in to the wall socket. The extension cord's AC plug may be making better contact to the wall socket, and the socket on the extension cord is making better contact to the unit's AC plug. It could be something this simple.

In my mind however, I sort of think that there is a very intermittent fault, and it does not show up too easily. Sometimes moving a device can disturb it in such a way that its fault may not show up (fault gets to be masked). The fault may come back to haunt you. Time will tell which scenario is the right one.

Most likely there is a cold solder connection on one of the circuit boards, or a connector, or any anything else in the audio path.

It is suggested to not use the unit until it is properly serviced. Depending on what is being effected internaly from the cold solder connection it is possible to have some damage.

I had the same problem and tried it both ways. The sound did come from the rear but was very soft. I used the microphone that came with the receiver to optimize the sound and that also helped. But what I really noticed was that certain movies make use of the rear speakers more then others.

Manual

There are 2 things you can try, first ensure that the digital transmitter is fully inserted into the slot of the main unit. Secondly do you have any other wireless devices near such as cordless phone or wireless network equipment? See page 5 of the installation manual as per this picture.......

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.)
