Question about Samsung Home Theater Systems

1 Answer

Speaker cables are too short

This Home Theatre unit comes with speaker cables that are too short for my intended installation. They appear to be aluminum cables and have a proprietary plug to attach them to the back of the unit. I would like to replace them with longer speaker cables but have two problems. 1.) Will using copper wiring change the electrical characteristics (impedance? resistance?) in a way that will negatively impact the signal quality? 2.) Does anyone have a source for the plugs that are attached to the cables? These might be a proprietary design.

    I had considered this solution, thanks. Soldering on an added length of cable especially going from aluminum to copper might effect the signal (that was what I was asking in #1) and would probably be an invitation to electrolysis/corrosion. Going from aluminum to copper isn't acceptable without a special connector as far as I know. Best practice would seem to be locating a new female plug and and going with a copper. I was hoping to find a source for the connectors.

    RCA jacks are not going to fit the back of the unit and the original cables are a very light aluminum (24/26 gauge?) so I would guess that you are suggesting light aluminum wire to RCA jack to RCA jack to copper wire. Isn't this going to degrade the signal? I thought that the fewer connections the better.

Just go to Radio Shack and buy some RCA jacks, the length of wire that you need and a soldering iron. Those inexpensive extension cords (12 and 15 foot) at the dollar store make good speaker wire, as copper is better. Just cut off the ends. Speaker wire from an electronics store is expensive.
If you decide to go to Radio Shack or similar store, the clerk should be able to explain everything to you, if not, run, don't walk to another store. You will eventually find someone to help you. If you don't know how to solder, just go to google and type in "how to solder". I'm sure you'll get plenty of hits.

Post back here for any further questions.

    No, you don't want to go through all that, and yes, that would just make a mess of things. What is the model number of your unit, I'll be glad to check it out. You should still be able to get the required jacks at Radio Shack, as they have quite a selection of jacks. Take the unit with you if you have too.

    OK, mikeidk,

    Those cable connectors are indeed proprietary, and readily available on Ebay with up to 40 feet of cable on them, just search for Samsung audio cables and connectors at ebay. Sorry about the bad steer.

    Thanks for the positive feed back mikeidk. By taking the time to vote, not only did you benefit my rating, but you just put a FixYa out there on Google where hundreds if not thousands of people can now benefit from _our_ efforts. If someone types in anywhere close to your subject line: "Samsung Home Theater...speaker connectors", they will now have a fast, correct answer. Thanks again for a definite load off the FixYa servers and database.

    Peace Brother,

≥Check the connections.

≥Turn the volume up.

≥Turn muting off.

≥Switch off the unit, determine and correct the cause, then switch the unit on.

-Using the unit in a hot environment without proper ventilation.

Getting an error display as "Push power protector" in my Sony Home theatre - DAV DZ777. what is the solution.

Turn off your unit at the power button. Check speaker outputs for a short circuit - also check other end of speaker cables for a short. If you can't find an obvious problem then disconnect all speakers and power up the unit. If all is OK then connect speakers one at a time (this should be done with the unit powered OFF) and power up after each conection. This should identify which output is causing the problem.

If that does not work then it's an internal fault that will require a service engineer to identify - but I hope that is not the case!

The message appears when there's a short at the amplifiers. Disconnect all the speaker cables and try again:
  - if the message is gone then one of the speakers is shorted ; connect them one at a time till the message comes back - junk that speaker and get another one.
  - if the message is still there then one of the amplifiers has failed - take to unit to a repair shop, that amplifier must be replaced.

Hi I have the Sony DAV-HDX285 home theatre system and I'm trying to get it to work with my Vizio 47" HD tv. I go thru the speaker setup with the dvd supplied and all speakers are working tthu the home...

I assume you mean the TV sound only comes out of the TV. THAT would involve internal audio controls at the TV.

Why don't you just connect the TV-related audio directly from each source to the DAV instead of through the TV, which adds NOTHING to the sound quality and may even degrade or limit it.

"PROTECT" appears on my DENON DHT-500SD

Sounds like a speaker wire is shorting against either another speaker wire or something metallic. Check your speaker wires to make sure they're not shorting (touching). If that doesn't work, I'd take it to a repair facility. Good luck!
