I have a nexus 42 inch tv and lost sound. Not sure if my one year old pressed something on the remote because netflix, and DVD work fine

Hi it sounds like it has had an elctric fault like a resistor failing.
The click you heard would be a internal switch that cuts off the elctric supply to the screen to stop furthe damage hapening.
It could even be something simple like a bad solder and in that case will need locating and resoldering.
How old is the telly and how often is it used.
When you switch it off leave it off for about an hour then try again if you have allready done this then it probably is a blown resistor are you sure nothing has been pressed on controll have you tried seeing if you can acess the menu screen via the remote and see if that comes up on the screen let me know ok

switch the HDMI cable end for end, maybe try a different port

Is it 7 years old? Marvelous. Exciting. the lifetime of Maxent televisions are 6 moths the most!!!
You're lucky.

I've had mine for nine (9) years and it fine, first make sure all coloured wire are connected to the sub correctly, press sys on your remote then press button 8 to test if the speakers are working then increase the volume to hear the spaekers. so to link TV audio/sound with DVD press sys then A-2 on the DVD remote, I hope these will solve ur problem?

Hi, I had the same problem. My vizio remote for my 42 inch 2 month old vizio also seemed to stop working. Here's what I did: My vizio remote (like most remote's nowadays) was designed for multiple components (tv, dvd, vcr, etc). All you need to do to make the remote work again is set it back to tv. Now, the confusing thing about vizio remotes is that they actually have TWO places where you can switch the remote to the appliance you want to control. One is on top of the remote, the other is on the BOTTOM. Switch it back to TV using the BOTTOM. My remote had stopped working because I had inadvently switched it to another component on the BOTTOM component switch.

take your tv and remote to a technician to check on your emitting diode and a photo senser, both are working but not very sensitive. the components are not gone but about to go. if you remove a senser from tv it can not receive, so that senser is sensing some thing, also check an amplifier just after a senser plse do that.
