Troubleshooting Panasonic SA-DK2 Power

I have a Panasonic model# sa-dk2 home theater system that will no longer turn on. I think it’s the transformer, however this unit contains two - would you know which one it would be? Kat Delong

I have to admit up front that home theater is not really my area of expertise. That said, I did a little digging and did come up with some possibilities about what is causing the power failure on your system.

My guess is that your Panasonic SA-DK2 home theater system is more than about five years old and is no longer under warranty. That said, there really are no user serviceable parts inside, so anything I tell you is not really a green light to get in there and go digging around - some things are best left to professionals both for the sake of your system and your safety. You can find some information on the SA-DK2 on the Panasonic website where you can download a user manual and find a Panasonic servicer near you.

Check the Source

Before we go straight for the transformer as your likely suspect, have you ruled out all of the obvious culprits first? You’d be surprised at how many people think that their equipment is faulty when it is the power source that has tripped. Plug in a lamp at that outlet and make sure that it is working properly first. Do the same with any surge protectors you are using (you are using surge protectors on all of your electronic equipment, right?) and make sure that the outlet that it is plugged into is good.

Check the Fuse

I couldn’t get too much information on your particular model, but most often it is a fuse rather than a transformer that is the culprit in home theater power failure. Most transformers have an internal fuse that prevents the equipment from drawing too much power. It is rare to have a transformer go bad without blowing the fuse first, and a blown transformer will likely generate a lot of smoke - it would probably be hard to miss.

You should be able to test the transformer using an inexpensive ohm meter. With the meter on the lowest scale, you can test each winding of the transformer to see if you can spot a problem.

Again, I don’t recommend delving into the innards of your home theater unless you have a real expertise in that area, but this will hopefully give you some ideas about what the problem might be.
