My Panasonic Stereo (sa-ak510) will not power on. The red light blinks and makes a clicking sound almost every 30 seconds. Does anyone know what this is?

Usually this means the backlights in the display are faulty

The problem is in the audio output ic, it is loading the unit into shutdown. The only option is have the ic in the stereo replaced.

The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

In regards to your issue with your SA-AK510 turning back on most likely you have a short and/or a bad connection on the unit. So what is happening is the is a charge going to the switch that is engaging the switch again after you turn it off. Note most modern electronics do not have switches like a light switch. They have an electric relay switch that turn off and on the device when the circuit is completed.

The first thing I would do is make sure that your receiver is not still in warranty. If it is I would call Denon's support. If you are not then the first theng to check would be the fuse. I have seen a few devices over the years where the fuse clip is not connected properly and starts to arc which in turn puts a charge on the board. Also you will want to look around in the areas that get hot to see if any of the installation melted off the wires causing you to have some exposed wires.

Hope this helps

just got back today for same problem. convergence went out. took to repair shop. $200 part plus $60 labor. second time in a year convergence went out. was told it will happen again.

You are missing 15volts. If this is a new TV, it could be as simple as a plug not fully seated on the power supply. Regardless, the repair should be covered by warranty and Panasonic is one of the best when it comes to taking care of the customer. Ifd nI can be of further assistance, let me know

power unit going bad

How many blinks is it doing? It has a built in self diagnosis code that it will blink. Pause a second then blink again. Count the blinks then let me know.
