Question about Olevia LT37HVS 37 in. LCD HDTV

1 Answer

Audio Problems When I have a comcast/motorola cable box connected thru the component inputs the sound will intermittently either sound scrambled/garbled or has a loud tone. This problem also occurs with a dvd connected in the component inputs too. Also if you select 720p or 1080I in the service menu on the motorola box there is a loud popping sound thru the tv speakers even if the audio input cables are disconnected. It seems the popping is from the Y input. If you switch the resolution to 480i or 480p it seems to go away. Any ideas where the problem is?

I can't get audio to work on my Samsung UN40HU6950F UHD TV HDMI 1 input using the Time Warner Cable Cisco 4742HDC cable box.

if all 4 inputs work with another input source(i.e. your Motorola box) it indicates the issue is with the TWC input source. Also check your HDMI cable to be sure it is in good condition & properly plugged in on both ends.

The sound does not come on when first turned on. I have to turn the unit off-on several times before the sound works. I utilize compast for tv access.

Try using a different input. For example, if you are using an hdmi input, try using a component input instead (Its still HD) A sure way to test this is as such. Remove all cables from the Comcast box to the tv. Now, run your coax from comcast into the back of the comcast box. It will say something like "In from antenna" or "cable in." Now run a regular coax cable out of the box, into your tv. This will be labeled as "out to tv or vcr." Now put your tv on channel 4. If the sound is ok, then you know its a problem with your input on your tv. If you still have the issue, it is probably the Settop Box from Comcast. Please note, this is just to test the tv. This cable will not support HD television feeds. Hope this helps.

I get inconsistent results in using the auto channel search such that I can't synch the TV to the Comcast cable box. Any thoughts? This is a new Pyle 15 in. LCD TV TV/DVD.

use any other connections to your tv, not the one thru rf input.
i.e: audio/video, component,hdmi, etc.looks like there is a tuner issue, plus you'll get a better picture quality by using other options. if that' hd set, you will take advantage of this feature, if not, just improved picture and no hassle to screw in that "comcast's" thick RF cable in.
Good luck,

When I connect HDMI from a Time Warner DVR to my Vizio thru a DVI/HDMI adapter, I get no sound. I can only get sound if I use Component input (RGB+ audio R&L). Is this a DVR issue or a Vizio issue?

Use the Time Warner remote and hit the settings button twice. Scroll down to "audio: digital out" and select HDMI. That solved it for me.

The only issue I have now is that I also have component sound outputs going from the cable box to a receiver. When I turn off the TV while the HDMI cable is hooked up to both the box and the tv the sound goes out to the receiver...

No sound on NON HD channels

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

Turn off closed caption on input(component) on Sharp Aquos 42"

I have a Sharp Aquos 46" and go a Comcast HD receiver as well, and had the same problem turning off the Closed Captioning. I order to turn it off you need to go into the box user setting by (starting w/ the cable box and tv on) pressing the power button for the cable box then the menu button for the cable box. This will open up the user settings menu. Just toggle CLOSED CAPTION to DISABLED.

Panasonic legacy connection

s-video is a legacy connection. legacy means obsolete and this will impare your image.

what you should do is connect the cable box and blue ray directly to tv with hdmi cable, then run audio cables back to the reciever from these devices. the vcr and regular dvd player would be routed through the reciever the conventional way. you would have to change the inputs on the tv between the cable box, and blue ray if u have one, and a seperate single tv imput for components running thru the stereo. you would have to use the reciever to select between audio sources, and the video sources between the vcr and dvd only.
