Whats a sound bar

A sound bar is an additional home theater sound device separate from your TV. It is generally designed to be set below, mounted below, or mounted above your TV and is specifically designed to enhance your home theater experience by providing you with clearer, louder, and more rich audio. Somw sound bars come with wired or wireless subwoofers. A sound bar is a less complicated alternative to a surround sound system.

I bought this from a thrift store for $10 bucks. It works fine in normal mode but when I switch it to surround mode everything turns into static. No matter what input I select or what surround mode it's...

It sounds like you are activating a test mode to set your surround speaker levels.
Usually you should do this before using any surround sound modes.

If you could post the exact model; we can search for an owners manual.

Trying to hook up this surround sound to a hdmi 1080p tv and cant get the speakers to make anything but background static. not sure if wires are connected correctly

You probably have to use the TV remote,go into the sound settings,and change it from stereo to whatever options there may be for surround.Good luck! Greg

Brookstone wireless headphones have static along w/ tv sound

Well I just plugged into the cable box and that worked. On my old tv as well as my newer one the only audio out was an optical I had bought an optical splitter (one input for my sound bar and the other one to the optical to Rca) and an optical to rca for the headphones. This allowed me to use the headphones on all things going through the tv. For some strange reason it no longer works that way (just got my new tv this week). I bought all pieces on Amazon for a nominal cost. I'm going to doublecheck all connections again tomorrow.

Harman Kardon AVR 500 Only works in NON-Surff mode ?

This is a good indication that the surround processing section has a problem. This can be anything from a supply voltage being missing to a defective processing IC. Without testing inside the unit, it wil be difficult to determine. With surround procesing turned off, the entire section is bypassed. This is why standard stereo mode sounds OK. The static sound is digital noise and can be poor processing or a bad D/A converter IC.

Hope this helps,

What source? Digital or analog (analog is only stereo).

Sound is out when you turn tv on.

This model uses a single "Surround/Sound" circuit board. All of them go bad---probably why he was using a surround sound system for the audio.

Board part number is: X480242 and it is no longer available from Hitachi---the only way you can get it fixed is to remove the board in the set and have it sent out for rebuild--company is PTS electronics--they repair/rebuild all kinds of boards.

Considering the cost for repair/rebuild is almost 200 dollars it may be smarter just to do what the other person did--get an inexpensive surround sound and get the audio that way.

I worked on a lot of these sets with this problem--some brand new ones were bad this way--

With the back off of the set you will see on the far left wall (as you look from the back) the Surround board--it is not hard to remove (several plugs and a few screws).

This was in my view a design flaw--the board is full of surface mounted IC chips and several are mounted near the audio output IC---heat from the output chip over time causes all kinds of bad solder connections.

I saw one tech in a shop where I worked spend three hours trying to resolder one of these boards (special soldering for surface mounted parts etc) and the board still did not work right.

That board got sent out for rebuild and worked fine after. Lots of these have problems where when cold or hot sound problems come or go.
