Power cord orientation and Blu-Ray player - does it matter? (1 Viewer)

[mackjay]

Hello!
I recently got a Panasonic UB820 blu-ray player. It's a great machine once I get it going, but when I turn it on it just freezes with the Welcome! screen until it turns itself off several minutes later. I've tried unplugging, resetting...nothing seemed to help. I contacted the vendor and was told it's possible that the power supply could be at fault...I disconnected the power cable from the back of the player, turned it around and re-plugged. Now the player is behaving normally. Is this really possible? Did I have it in there backward?

Are you certain you're using the power cord that came with the player?

I don't remember if it's a polarized one, in which case it can't be inserted the wrong way into the player. If it's not polarized, it doesn't matter.

Fortunately, I have an 820 sitting on the floor in my HT, and I can check when I get home.

That cord is a polarized one and can really only be inserted one way. It's possible you had in the wrong orientation the first time.

That shouldn't be possible with a polarized cord and jack. You'd have to use a non polarized cord to be able to reverse the intended polarity.

I just read your post again, and realized you are using the wrong power cable. As has been mentioned, the 820 uses a polarized figure-8 cable, which can only be connected one way. However, a non-polarized figure-8 cord can be plugged into the player, though it shouldn't be used, because the polarity can be wrong.

They are very similar, but there's a crucial difference. The polarized cable has one round and one square side, and the non-polarized has two round sides.

The cord should look like this...

Not like this...

Wow...Thanks...I wonder how I got the wrong cord. But I've discovered by reversing it the player works perfectly ,so I guess problem is solved.....

You can get the correct, polarized figure-8 cable for a few $. It's probably worth it, just to be certain it's hooked up right.

Or just mark the sides of each end - on the player end, mark the side that should be squared off and then on the plug side mark the side that goes into the wider portion of the outlet. By doing that you'll be able to get the correct polarity without experimentation.
