    Sound from the midrange/tweeters disappeared overnight, only had sound from the woofers/low freq speakers. Hitachi sent a software upgrade. That turned the high freq speakers back on, but disabled the low freq speakers. Now, the LOUDNESS and BASS BOOST controls have no control of the sound. I've unplugged the set from the wall and re-started it, but that didn't help.

    I ,too, have that same problem. Turned on the TV after an overnight and the sound quality is muffled and low. Do not know what to do. Called Cable, but I think the problem is with the TV.

I fixed it by turning the main power switch off for thirty seconds and then turning it back on.

How do I hook up my 55 inch led tv to a stereo for better sound


In many cases newer tv's do not have an audio out, some have a headphone jack on the side (Small usually blue)

Otherwise if you are wanting to get better sound from a DVD / Blueray / Satellite / Cable box, You can put the audio from these devices into your sound system, then plug your sound systems audio out into the tv.
The video out from your devices will need to connect directly into the tv.

If using HDMI or S-Video that carries both audio and video, slitter / separation boxes are available, but usually degrade sound and audio quality.

The above would look something like

Cable box audio out (red / white) to Stereo audio IN. >> Stereo Audio OUT to TV audio in.
Yellow (Video) Cable from cable box then goes directly to the TV Video IN. Just make sure the audio and video cables are going to the same section (Some tv's may have multiple audio / video in's

I have direct satalite tv VR 6050 kenwood surround sound tuner vizio tv, dvd player, and a vcr, Im confused on how its hook up and what order should it go something like sat in to sat box to kewood...


that reciever is not going to carry a hi definition video signal, it doesnt have either hdmi or component video inputs.

you can still use it, but if you run the picture through the reciever, it will have poor quality.

heres how you are supposed to hook it up:

find the single,m yellow video jack on your sattelite box, and hook that up to the "tv" video input, then hook the laft and right audio outputs from the cable box into the "tv" audio left and right inputs on the receiver. hook up the dvd player and vcr in the same manner, using "dvd" and "VCR" (if labeled as such) inputs on the reciever.

finally, send the tv video and audio outputs to the composite video in and left/right audio inputs on the tv. the video will be running through the reciever, and when you use the reciever to switch the sound source, the video will also be changed. you could get better picture quality if you ran the video directly to the tv using component (seperate green, red and blue) outputs/inputs, and bypassing the reciever on the video end, but then you would have to change inputs on the tv AND reciever to change from your cable box to your dvd player.

TV Hookup


The TV is NOT a source of high quality sound.

For the best serious audio I would recommend drawing the audio-only digital feed from the Cable Box via its highest quality audio output. Then turn the TV's volume down. Also run the vanilla RCA stereo audio pair from the cable box to the TV in case you just want to check the weather.

Poor sound cqality on a Samsung DLP TV


If you are receving your HD via a cablebox, check the volume and audio settings in the box's menu. Some boxes have internal volume controls. If the level coming out of the box is below a certain level, you may experience low or poor sound quality. You can also check the audio settings to assure that they are set to the original settings.

Sound quality poor


Try moving the audio and video cables to a different input.
Or the cables maybe bad. That's what happen to me.

Poor picture quality & audio reception


If the input to a HD tv is not in HD format the tv won't display an image very well. Be sure your input to the tv is compatible with the tv's technology for optimum performance quality Also re-check the input source (such as converter box, dvd player, etc..) and be sure you have the correct input/output ports connected properly. Try to reset all yout tv settings back to manufacturers defult specs. When an input signal is sent to the tv most modern tv's have software built in to select the proper format to display the input image. There may have been a mismatch communication error when your tv software tried to "handshake" with your converter box input signals from its firmware. So try a reset solution and re-connect the tv without the converter and see if that helps. If not e-mail me and I'll determine if the tv needs technical servicing.

Audio from tv


It sounds like you have the red,white rca cables hooked from the back of the tv to the red,white input on the stereo or the same connection from you hd sat box or hd cablebox. In order to get the same sound quality from tv service as you do on dvd is to run a fiber optic cable or digital coax audio cable from you hd sat box or hd cablebox to your stereo which means no red,white rca cables at all, take them out. Also once you do that you must be on a hd channel to get equal sound quality of a dvd movie. I know on some hd cable or hd sat boxes you have to go in and set them up to dolby digital as well after you hook it up the way I was explaining. Try this and I hope this is helpful.
