I have no sound/ I have a picture my tv is hooked up with coax cables- i have unplugged the tv that didn't work the volume is all the way up on the tv--- we have reset the factory defaults-- no surround sounds only the tv

If the DVR has RCA-type connectors, yellow to yellow for picture, and white to white for sound. Tune tv to line input.
If the DVR supports outputting everything on coax, use a piece of coax cable, and tune tv to channel 3.
Your coax cable from wall has to go into DVR first, then out to tv.

It sounds that the main digital board to your TV has the fault. To check and locate the fault to this board is a very skilled work. Contact any service technician.

Tries tv and cable box unplug,replug it back like about an hour later.For the tv to do a resetting itself back to the factory setting.The cable box to reboot and upgraded it software.Than go in to the tv Menu go to Audio Setting go down and do a resetting back to the tv factory setting.By doing these steps u have a great chances to get ur tv audio sound back.Not have the same problems after this than the tv Tuner signal board it is shorted in the audio ICS modjulation sections.Tries websites like Shopjimmy,com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

I have HLN 5067wx after replacing the color wheel and inserting new lamp There is sound withou the grinding but absolutely no picture; What is going on?

Your TV output is a pass-thru from the coax cable then. The only solution- turn the volume down, or unplug them.. Or get a cable box. A VCR may work as a temporary cable box, and if you have a remote for it, you should be able to just turn off the audio at any time with a VCR remote. (unless the VCR also has a pass-thru only audio output)

often people make the mistake of hooking their devices to the tv using more than one input.  a cable box for example may have many different types of outputs but you are only going to use one to the tv (preferrably the highest quality connection). try switching the inputs on the tv to see if you get the same picture on two different inputs.   If using s-video, you will also need a red & white RCA cable for audio.  The order of video cable quality from lowest to highest is this: Coax(screw on), Composite(yellow,red,white), S-video(Round)+(red,white), Component(video=red,green,blue), HDMI(carries HD video & sound)

You need to set up the out put of your DVD player. First hook up a non hdmi output to the tv, either component or coax. You don't need to hook up the audio. You should get a picture from this connection. Then you can go into the menu and set your hdmi output to match your tv, probably 1080i. You may have to turn your volume up higher when using the hdmi cable than not. I hooked my audio up directly to a surround sound and don't use the tv's speakers.

If your cable converter box has audio/video connections on the back of it,you don't need to worry about using that RF coax connector. Just hook it up the same way your DVD is hooked to the TV input jack. Get a 3-wire cable (yellow-red-white)hook it to the same colors on the back of the cable box and hook the other end to an unused input on the back of the TV. Then select that input with your remote and watch TV.

A few possibilities - try volume + on satellite box itself/reset satellite box

Are you using coax or RGB cables? unplug and replug composite or component audio cables if using those
