42 inch LCD TV loses sound on commercials

I have a 42 inch LCD Toshiba TV 42LX177 that over the last three months loses sound on commericals on certain Time Warner cable channels. No other TVs in the house have this issue and TWC has verified the cable feed is fine. I have replaced the same cable feed with another TV and it works fine. I have also changed different audio settings on TV and got latest Samsung cable box and still has issue. It has to be a TV issue. Please HELP!

Try resetting the TV to factory defaults.
MENU > Setup > Installation > System Status > System Information > Factory Defaults.

If that doesn't help, it might require servicing.

Insignia 42 inch LCD

I have an Insignia 42 inch LCD that I bought last February and yesterday I noticed it has a thin vertical red line on the left hand side of the tv.
Has anyone ever seen this before and what is it?
How do I fix it, my warranty is of course over with now!!
PLEASE HELP

Hi ANGDAK28,
So sorry you're having problems so soon after the manufacturer's warranty has expired. I am by no means an expert on this, but what I'm seeing in other online support forums regarding red vertical lines on lcds suggests that this could be caused by a number of issues, ranging from wiring to the circuit board to the actual lcd panel - at any rate, it doesn't sound like an easy fix. You may wish to contact Insignia at 1-877-467-4289 to see if they can offer any recommendations over the phone, but they could also arrange for a tech to diagnose your television and give you a repair estimate (there would be a basic charge for the diagnostic, of course).
Hope this helps!

24 Inch LCD Panel - Fan ?

Hi
Now forgive me for maybe sounding stupid but I thought the 24 Inch LCD panel did not contain any cooling
fans.
Today I noticed a dark blotchyness starting to appear in the bottom left hand area of the screen, I have this very same problem with my iMac which contains fans for obvious reason.
When I place my hand next to the the underside of the panel 5 to 6 inches in from the left hand side I can feel a faint blow of cold air.
Now this to me says that this panel has a fan inside ?

just come in and turned it all on, placed my hand where I describe and there is a cold downward blow.....

I am using ALSA and Icecat. When I play any html5 audio/video it works, but the next time i click on another audio/video link I lose sound.

I am using Parabola (a fork of archlinux), Icecat 31.4 and ALSA
Icecat and firefox seem to hold onto the soundcard when I click on a new html5 audio/video link in the same tab. The next video/audio element loses sound. If I wait 10 seconds and click back to the start of the audio/video, the audio returns. I often get cpu spikes for icecat when it happens.
I have tried this with both motherboard and usb sound and I get the same problem. I have disabled extensions (addons) in Icecat, deleted profiles, reinstalled the browser and even installed firefox from the AUR and it still occurs.
I have disable gstreamer in about:config and restarted and it still occurs.
My .asoundrc is this:
pcm.!default {
type plug
slave.pcm "hw:0,0"
All my other audio applications work. I have noticed that if I use pulseaudio it fixes it, but it should work without anyway, like it used to. I think something happened after an update, but I'm not sure.
Any help would be appreciated. I know it's not a big problem, but it's really frustrating and I've had it for ages. I even switched browsers to get away from it.

*nerding out*
I am not an expert in this and if we get stuck I have found a mailing list for the alsa project that can be contacted: http://www.alsa-project.org/main/index.php/Mailing-lists
Gstreamer is disabled in Firefox as well as the os?
Since you are seeing issues with ogg files and moving video/audio combination I started to dig into file formats {sox http://sox.sourceforge.net/soxformat.html}
For ogg would the file format affect the "raw"?
defaults.pcm.file_format "raw"
Updated libraries
alsa-lib-1.0.6-8.FC3
alsa-utils-1.0.6-3
No no, here:

Second user accont loses sound.

I set up a second account for my husband and it loses sound frequently. I login to my account-the sound works, then login to his account -it doesn't. Not the mute/volume. We restart, it's fixed, hour later- off again.
I haven't tested it to see if it works if I completely logout of my account, I just thought of this as I was typing it, but is there a common problem with this? I can't find any settings to adjust, etc.
I'm not technical, but I can follow software step instructions if pointed in the right direction.
Thanks.

There you go. Since I'm the only user, but have test accounts that I rarely log into, I've disabled FUS, finding it a resource hog.

Exporting with Adobe Media Encoder CC 2014 loses sound.

So... I've been having a hell of a time with the new Adobe creative cloud when it comes to video editing. The drop of .flv format, unable to straight export .H24 formats from after effects, it's a total nightmare. Here's the issue, to export as a .H24, you now have to use Adobe Media Encoder CC 2014. The biggest issue, however, is at the end of the export, when you open the video, half of the video's sound is mysteriously GONE. Just gone. If you go back to after effects, look at the file and the audio, the wave forms are there. There's nothing that would make it lose sound. Audio is selected on export... I have no idea what's up. Editing videos for youtube was a snap in previous versions of After Effects, now It's becoming almost impossible.

I think the same problem:
Part of audio missing in mp4 AAC rendered files from Watched Folders
Probably with cached files. Try this: Adobe Media Encoder 2014.2 Part of audio missing in mp4 AAC rendered files - cache problem? - Video Production Stack Exc…

Font smoothing issues with Samsun 23 inch LCD

I am having a font smoothing issue with my MacBook and my Samsung LN-S2352W 23 inch LCD (http://www.samsung.com/Products/TV/LCDTV/LNS2352WXXAA.asp). I am using the mini-DVI to VGA adapter and the plugging that into the VGA port of my LCD. It doesn't matter which app I run, but as long as it has fonts, they come out blurry, hazy, colors bleed, etc.
I have played with the font smoothing settings and that has not helped at all. I have heard of TinkerTool and will try it to see if it makes any difference, but am not expecting much.
I also have a PC running Windows Vista and I connected it to the VGA port of my LCD. Wow...the difference in picture quality was astounding. I'm ******. I want my MacBook to look that sweet on my LCD.
Anyone have any thoughts? Can this be fixed?

TinkerTool didn't make any difference for me. I played around with it and found that there was no improvements using it or disabling font smoothing.
I have watched DVD's on this LCD being played with my MacBook. I have seen 2MB+ full screen digital pictures. Both the DVD and digital pics look absolutely amazing on it.
It's only the fonts that appear blurry or in some areas they appear to have a shadown to the right. This happens with any text that appears in every app.
Keep in mind too, Windows Vista looks perfect on this display, but my prized MacBook looks really sub-par.
I'm not quite following you on changing the display preferences to change to pixel size to that of the MacBook...

Why do I lose sound when I try to make a dvd from imovie to idvd. The sound is all there in iMovie, but when I make my dvd, I have sound for about 3-4 minutes and then its gone.

I have made a 1 hour 30 minute dvd in IMOVIE. The video and the sound are perfect. However, when I make it into a dvd on IDVD, I lose sound after 3 or 4 minutes. Any Suggestions?

Hey MichiganMan32,
I found an article that looks like it applies to that audio issue you're experiencing. Check out the following troubleshooting steps here:
Resolution
Make sure the audio track has not been muted in the timeline.
Switch to timeline view by clicking the clock button in the iMovie window.
There are three checkboxes on the right side of the iMovie window underneath the sound icon. These checkboxes correspond to the video track and two additional audio tracks. Make sure all three tracks are selected. Any deselected tracks are muted.
If you are using iMovie 3 or later, check the "Edit Volume" option to see if it is selected. If so, make sure the volume of the affected video clips is not set to its lowest level, or try deselecting the option to Edit Volume.
See if the volume in iMovie is set to its lowest setting. Directly under the Preview pane in iMovie is a volume slider. Set this slider to maximum volume.
Make sure the computer's audio is not muted.
Quit and reopen iMovie, then check the clip to see if it now plays with audio.
Check to see if any of the video clips you have imported are in the MPEG-1 format. MPEG-1 clips will lose audiowhen you export them as part of your iMovie project.
Quit and reopen iMovie, then reimport the footage from the camera. Play the newly imported footage and see if you now have audio.
If you are using an analog to DV converter instead of a camera, make sure the audio connections are good between your VCR or other analog device and the converter. Check the documentation that came with your converter for more information.
Check /Library/QuickTime/ and ~/Library/QuickTime/ for any third-party plugins. Remove them if present, log out, and log back in. Check to see if the issue persists. If not, check with the manufacturer of the disabled plugin to see if an update is available. Note: The tilde (~) represents your Home directory.
Note: "Apple Intermediate Codec" and "QuickTimeMPEG2" are Apple components. For more information about a particular plugin, select the item in the Finder and choose File > Get Info. Look at the version string of the Get Info window to see if the plugin developer name is listed.
iMovie is missing audio on import, export, or playback

Can Reliably Lose Sound Effects On 10.4.5

I found a way to reliably lose sound effects on Mac OS X 10.4.5. I will report this to Apple using Mac OS X feedback.
1) Enable Fast User Switching.
2) Login as user1 and note that sound effects work.
3) Without logging out as user1, login as user2 and note that sound effects work.
4) Without logging out as user2, go back to user1 and note that sound effects still work. Then logout from user1.
5) Go back to user2 and note that sound effects no longer work.
6) Reboot system to restore sound effects.

Hi, Richard.
One question: are you using USB speakers? Have you tested this using only the internal speakers on your iMac?
Good luck!

Gradient banding in Samsung 20 inch LCD

Now idk where to begin, ok here's the best info i can give
I just assembled a new pc for graphic work/budget gaming 2 days ago:
intel core i3 530 mhz
2 gb ddr3 ram 1333 mhz
xfx nvidia geforce gt 240 1gb ddr5
windows 7 ultimate 32-bit
Samsung Myst Eco B2030 widescreen 20 inch lcd monitor
Now when i opened an old psd which contained some brushing and gradients, i could see bands in the gradients, even the wallpaper i put had bands on it. I even noticed that everything on my lcd looks hellish sharp, and when i force my head really close, i can see small square pixels all over the l cd. Is it due to the analogue output(VGA)?, should i switch to DVI?
I use 1600x900 res (native) at 32 bit
Then to test whether all gradients look the same, i opened a new ps document and made a black to white gradient, but it was smooth, there were no bands in there. But when i made a simple white box, applied full gaussian blur, and zoomed in around 2000% i could see the gradual bands again though not as bad as in the colored psd. It seems the problem only happens when i give a glow, or blurs. Then i played Splinter Cell Conviction (everything Maxed out) and again i could see gradient bands forming up in dark places, like when i die and a small cutscene is played, i could see gradient bands on the 4 corners. What could be the problem, is it the card? the lcd? i am new to lcd monitors so i dont know how to calibrate or whatever.
Please check if anyone else can see the bands on their lcd?

Regarding calibrating your display, it's not strictly necessary, but you did mention "oversaturation" in a post above. It's certainly your call whether you want to make your color-managed applications put out calibrated color.
Re switching to DVI, that's falling out of favor... How are you currently cabled to your monitor? HDMI? VGA? You've mentioned both. DVI would CERTAINLY be better than VGA.
This "Coarse effect" you speak of... Are you talking about jaggy fonts, or what? If so, do you have Font Smoothing enabled?
When I first switched from CRTs to LCDs (in 2004) I marveled that most graphics created by people using CRTs were actually butt ugly, simply because they could not see the actual image content very clearly and tended to overlook things and overcompensate for their own monitors' shortcomings.
On a good LCD using a good interface (DVI or better) you can see every pixel as a discreet element. That's a given.
After my switch from CRT to LCD I had to reset my perceptions - I had thoughts just like yours! After a while you start to realize that what may look oversharp and harsh to you may even still be too subtle for CRT users. For some time there's been a mix of CRTs and LCDs in the world, though honestly lately I've started to ignore the former as they are truly a dying breed (just try to buy a new CRT monitor nowadays). It is not wrong to concentrate solely on making graphics look good on ultra sharp LCD monitors. Don't be too hard on yourself for what you've produced in the past, when you couldn't "see clearly" yet.
That said, I should note that there are some LCDs that are not sharp at all. From time to time people post on this forum that they have trouble seeing the Photoshop UI elements at their fixed small size, and as you're no doubt aware now with your monitor there's really no problem seeing them on a very sharp display.
You could try taking a macro photo of what you're seeing on your display that you don't like. Other than that it's very difficult to communicate about such issues on a forum.

Powerbook with Syntax Olevia 23-inch LCD TV Monitor

Hi there,
I got a 23-inch LCD TV Monitor from Syntax Olevia and somehow it doenst work with my powerbook.
The thing is when I connected it to my windows laptop, it worked just fine, I should say perfectly instead. Then I tried it on my Powerbook 12-inch, the Mac recognized the display, there was a VGA display on but when I turned the display on, it says 'NO PC SIGNAL'. You know, I'm ****** !
I have been on the phone with Syntax Tech Support for an hour, then with Apple for another hour, they suggested me to do everything try to get it works, everything they could find, everything within thier knownledge.... COULDNT CHANGE ANYTHING!
So the last thing the Apple guy suggested me is post a topic question here, to see what everyone says and if somebody out there has got the same problem, please do reply so, even you got it worked or not, just reply so I can have some experience. It might be compatibility problem but I don't know, not with a monitor I would say.
So here the LCD name and brand:
- Olevia 23-inch LT23HVX by Syntax.
I would appreciate for any answer, I'm looking forward to it.
Thanks all
Powerbook G4 12' Mac OS X (10.4.5)

Hi,
I'm not familiar with that monitor, but its resolution might be higher than your PowerBook can handle. I have a first-generation 12-inch PowerBook, and it seems that it can't run any of the Apple Studio monitors currently being sold. If that monitor can display a resolution of 1024 x 768, try that, as your PowerBook can certainly handle that resolution. Another thing to try is to see if you can find a friend or coworker who has a similar PowerBook (or any other Mac), so you can try connecting the monitor to that machine to see if there is a similar problem. If no Mac can drive it, you would probably have a good excuse for returning the monitor.
Hope this helps,
Ken
