Tv setup - cannot get past auto channel


Connect the TV to the Comcast box using an HDMI cable, then set input on the TV to HDMI - that's all. You then select channels on the Comcast box , not the TV (although the TV remote can be programmed to change channels on the cable box)>

I have comcast remote and granddaughter turned tv on side panel. Now screen is fuzzy and I can't find remote that came with tv. I get picture back?


Hello Mary and thank you for choosing FixYa today for your online technical support needs.

When you say the TV is FUZZY, do you mean that there is no picture there at all?

It is possible that your grandaughter may have changed the VIDEO INPUT MODE SELECTOR on the TV by accident when she tried to turn it on with the controls on the TV itself.

Most TVs have a button right on the front of the set itself labelled INPUT which allows you to switch between the various input modes. That button should be located right beside the POWER, CHANNEL, and VOLUME buttons on the TV's front panel.

You may simply need to press the INPUT button and select the proper INPUT SOURCE for your Comcast cable box.

The proper INPUT MODE for your particular setup will depend on how your Comcast cable box is connected to your TV. If your cable box is plugged into your TV with an HDMI cable, then make sure your TV INPUT MODE is set to HDMI.

I hope this helps out, and please feel free to comment back to this page with any additional questions or concerns and I will respond back.

If you do need additional help, please be sure to include the exact model number of your TV and of your Comcast cable box as well as how the two are connected.

Good luck and take care.

Joe.

Have a curtis tv , trying to run autoscan, it runs, but it doesn't locate any channels. I have a comcast converter box also. Not sure why autoscan isn't working. Or do I have to set up my comcast...


For the auto scan to detect there must be channels present on the CABLE that is connected to the RF input- TUNER INPUT- of the TV.
So check with your cable operator for the channels and you can connect. however if you are using a digital box then the channels are memorised on the box as only the output of the box is connect to the video/audiop inputs of the TV. if so select line in/video 1/2.

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.

Hdtv picture freeze


I also have a Brand new Sony Bravia 52" LCD with Comcast Cable (motorola box).When switching between HD Channels sometimes the left side of the screen shows a smushed version of the new channel, and the right side is a frozen picture of the previous channel. I correct this by switching to a non HD channel and back. Cable or TV problem I wonder?

LG TV renote not worknf on 4 new sets


Hello,

If you have a cable box (otherwise known as a set-top-box) that you have to turn on when you turn the tv on, and you use to change your cable channels, the LG remote will not control it. The LG remote is strictly for the tuner built into the television, and is not capable of controlling the cable box.

You probably see "function not available" because you are viewing the picture on an external input of the tv (component, composite, etc). Your tv cannot tune stations in when it is set to an external input that you use to watch DVD's, cable boxes, games, and other devices. The tv is telling you that you can't change channels if it is on an input.

I hope this helps you...

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.

Tv has no signal


sounds like the EDID data has been corrupted in your main board. it can be reprogrammed but most techs will just replace the board. either way someone will have to come out and look at it. it should have a 2 year parts and labor warr on it. call LG cust service and get someone out there.
