I have no sound on mines. i get picture and everything

A power board will never cause a sound delay issue, if it's doing it on all channels its most likely an input issue, such as your cable box, fire stick ect

hi put some hear phones into the tv jack see if you can hear sound this test tells you the sound processor is working, also you can test the speakers with a meter, thanks

It all depends what has led up to the problem, however if there has
been no indication of something going wrong,ie. picture getting dimmer, the most common fix is to reset.
First just check all cables are firmly connected. If that does not work then....
Unplug tv, disconnect from cable box, satellite box, any receivers.
Also turn power off to them as well.
Connect everything back and turn on.

Here is a video of other generic problems that can go wrong on any
tv that leads to sound with no picture.
TV Has Sound But No Picture Troubleshooting Guide

A converter box for what precisely? And how long have you had this tv? No picture or sound may be a broken TV. It could also be that you have the wrong input source selected. What are some other odd symptoms, other that no picture or sound. What exactly are you trying to do?

Hi, i bought a wii a few days ago and like everybody else mine too was in black and white with a grainy picture. I have a Panasonic lcd flat screen and thought I had connected it corrected, I got somebody out to have a look at it and found out there are some connections on the side of the TV which I hadn't even noticed before, once I put the red white and yellow leads in these and set the TV to AV3 everything is in perfect colour. Hope this works for some of you.

Take care

I have the same problem...please assist

I sugest you to change the video resolution settings on the PS-3 to see if TV sets to any one resolution...if you have any other video out (analog from PS3)...connect the out to TV and check video at different resolutions. If PS3 has Deep Color settings turn it OFF.

I have a 42 inch hd lcd Heward Packard televsion with no picture or sound, it is just two years old. When I plug the cable direct without my cable box I get sound but no picture, the cable came out and tested everything and we tried to rest the tv but still no picture.

simplist solution, if the TV has an audio output just run that to the Bose system.
what type of TV are you connecting to?
Is the cable box an HD or digital box?

• adjust brightness setting when playing tv.
• adjust screen control located on flyback transformer.
• hope this will help.
