HDTV Sans Sound

10/22/2016 2:36 PM

I have a 32" flat screen TV about 1 year old that has lost it's sound. I have replaced it with a new TV and wonder if the old TV can be used as a computer monitor. Since I do Autocad©, a big screen would be great.

It's odd to see a new TV lose a basic function like sound after only 1 year. I'm wondering if some setting was accidentally changed. Did you run through all of the audio settings in the setup menu to make sure you had the correct choices for sound quality, balance, speakers, etc?

I've fixed a few friends' TVs that lost sound due to someone accidentally choosing 'second audio' or 'aux speakers', thus effectively muting the TV without using the 'mute' button.

...and check to see if the "language" setting was changed. My wife accidentally hits that button and it turns the sound off for certain stations.

My wife has accidentally hit a button which makes the NFL Football games (only) come through in Spanish on one of the main channels. Thankfully, over the years, I've learned enough of the language to enjoy the games.

There's the fundamental problem with all modern TVs and most other things, cars included.

"all of the audio settings in the setup menu ", all those video settings in the setup menu,

all of the source settings in the setup menu, all those channel settings in the setup menu, all of the settings in the setup menu is enough to overwhelm those of us over 50.

We just want it to work when we plug it in and turn it on.

Case in point. I just rented a car, a Toyota I think, doesn't matter, and the display was a nightmare. I just want the damn car to go when I put the key in the ignition! Oh, wait!!!!!!! THERE IS NO KEY, and nothing but some damn button to push. But wait, pushing the button won't do ANYTHING, if you don't stomp on the brake pedal!

What happened to KISS?

I don't need all the bells that require settings I don't understand and all the whistles that go off when I have no clue what they mean!

Ron should get a neighborhood kid, give him or her 10 bucks and they will fix it in one minute.

That changed when Americans stopped making them. Since they are made in foreign nations, the software to the item "thinks" in that language, not ours. Stuff does not follow the "normal" way of getting to the setting you want.

I propose the following: Congress pass (yet another) bill but this time make it so that all TV sets, cars, refrigerators, and all other appliances be manufactured to accept voice commands. That way the annoying thing will ask you seven times to confirm that you want it to short itself out and burn up in the atmosphere.

I see the preponderance of expensive boat anchors mounting up in our future.

Only good thing I have to say is, when these work, it is really nice, when they don't, they really, really, really suck.

You do not say which model TV you have,but some sets have the video/audio chip combined on one chip,and is installed in a socket.

If this is the case,it is easily repairable by replacing the chip.

Even though the audio/video is on the same ship,I have seen just the audio portion fail.

Sometimes simply re-seating the chip fixes the problem.

As noted in the link provided by Rixter,a 32 inch screen may not have sufficient resolution for close-up work.

If you will provide model and serial number,I will research the schematic and provide suggestions on repair.

Others are correct about SAP being on. If the TV does not have a VGA input than likely the 32 tv even though it says is HD is very low resolution and will not have a quality look running computer graphics at HDMI regardless of where you set the resolution. Inexpensive small TV's throughout history have very low resolution. Unless they are specifically made for high res. applications- and they will not be inexpensive.

Yes, no problem. I have been using a cheap 32" as a monitor for over 10 yrs. I use 1280 x 960 resolution. Lines on my drawings are wide and clear.

I had an old pickup truck with no key. I jammed a nail between the terminals on the ignition switch to complete the circuit. The starter was a foot switch. To turn it off I would reach up and slide the nail away from the hot terminal. It was almost too easy but someone who didn't know this wouldn't get any where with it.

I had an old Renault Dauphine when I was in high school. The ignition switch had terminal lugs screwed to the back. I used to amuse my friends by starting it by shorting across with a coin.

Have you heard the one about the ole boys heading to gig frogs late at night when the headlight fuse blew in their old pickup?

They discovered that a .22 long rifle cartridge would fit the fuse holder perfectly and were soon on their way.

Unfortunately, about two miles down the road that .22 got hot enough to self-ignite and shot the driver in the privates.

Was a near miss in the Charles Darwin Awards some years back. For hitting the balls it could still be seen as a unintentionally removal from the gene pool.

So he lost his credentials as a bonafide frog gigger?

Dummies should have fired the cartridge first, huh.

Seems this whole discussion has degraded to a low caliber!

How about 2 x .22 spent cartridges?

Losing one's credentials over a blown fuse sounds rather extreme sport for me to try.

I use a tv for a monitor (PC VGA input), 8 security cameras on 500Gig recorder( HDMI input), Internet (PCDuino-second HDMI input), video cd player(component input), and a vcr(video input) and just hit menu on the remote to select what I want to see and this Visio I bought used about 5 years ago....your newer tv should have an input that matches your video card output, cable it up and select the input you're hooked up to....you should be pleased with your new screen...

Re: HDTV Sans Sound

I have Mitsubitshi TV that acted in a similar way. The sound was distributed through about 12 to 16 small speakers in a line. It had a feature for biasing the sound to the left or right depending on the shape of the room. Actually a fairly nice feature.

The problem was that it would slowly drift off to one side and then fade out completely over several months.

To fix it, its program had to be reloaded from time to time. I got tired of paying the TV tech to come out and do this, so I downloaded the code from the manufacturer to a dedicated USB memory stick and do this myself if it needs it.

It seems the code I downloaded had the memory leak fixed so I no longer have to reload the program. Nothing like having the most recent version of the software to finally fix it!

I am getting nearly old enough, I could start having those.

Me too! I had never heard of that until I started working with an awesome programmer.

It is a term that refers to writing over memory that was supposed to be left undisturbed. Begining programmers apparently do that all the time.

I think the second definition should probably include forgetting things that used to be important at one time or another.

Here is a link to a service manual for a 32inch Vizio,if you are interested in repairing it .

http://www.manualguru.com/lg/32ln549c-za/users-manual/page-16

"Is that mud puddle very deep?" asked the stranger driving through.

"NAH! It only comes up to here on my ducks." replied the farmer,with a grin.

Moral:Don't get in over your head.
