Question about LG 42LD450 42 in TV

2 Answers

I have an LG 32LC7D TV that is hooked to Comcast cable. I recently went from Verizon Fios and set top boxes to a direct connection to the TV with Comcast. I get catv analog but when I scan the tuner it reports no digital signal. Previously it worked fine with Comcast and I received lots of digital channels with the QAM tuner. My Sony is getting the digital channels so I suspect something is wrong with my LG's tuner. Is this a known problem? And can someone help. Thanks in advance for trying.

    Thanks for the info. I'm still not sure that is the problem. My Sony Bravia 46XBR4 picks up a bunch of digital channels (it also puts them in order ie 8.2 after analog channel 8, etc)

    I have switched the cable feeds between the two and get the same results. Nothing digital on the LG and about 25 digital channels on the Sony. Maybe it's the type of signal to be decoded except I had Comcast about 1 1/2 years ago and it worked fine. If you can think of another reason I would like to know.

Hello

A few months ago comcast started making it mandatory to use a "Digital Adapter" to recieve anything but the basics channels on your TV. I also have comcast and they sent me a letter and a small survey to fill out.

The good news is that the Adapter is free(from comcast,for now!) so you just have to give them a call. You can also get one from ebay for $25-$50 if you rather own one.

I am curious to how you are getting a digital signal with your Sony. My TV's all lost signal when they switched and I had not installed the adapters yet(my Box was just fine though)

If you have any questions or need any further help let me know!

    I was thinking it could be a problem with the QAM tuner before I remember the comcast update a few months ago.

    If the QAM tuner is having problems it will not come up with those free HD channels. I have a Insignia TV that is a few years old that had a the QAM tuner go bad.........it still picks up anything outside of that fine. I would try and test if anyhting.

Wont connect to verizon dvr box, its connected to the video out cable and the fios tv cable.


Make sure that the dvr is not outputting a HD signal to your set - if it is, your set will not work unless you change the signal to 480 from the HD setting.

Hi,

Due to certain limitations of the Panasonic DMR-EH75V, it can only accommodate composite Video INput and give composite Video OUTput as well as the standard Audio L/R. Additionally, if your Verizon FIOS HD cable box has an RF OUT, that can also be connected to the RF/CABLE IN of the Panasonic.

Please refer to the simplified diagram below.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I just changed from Comcast Cable to Verizon Fios. Since the change I am unable to get a full picture on Fox News. There is a narrow horizontal picture with 1-2" black bands across the top and...


This is a function of your set-top box (STB), and has nothing to do with the TV. I know several FiOS users with the same trouble, and it's annoying but there isn't anything you can do to "fix" it. What is really strange is that the screen size can change even on the same channel, depending on the particular program being broadcast. It has to do with the aspect ratio of the programming from the provider.

Hook up vizio tv to fios box


Run HDMI from FIOS to TV directly, then run Digital coaxial or optical to the cbl/sat audio input of your receiver. That's it. If you have any more questions, just post a comment and I can help more.

Philips TV HDMI CEC EasyLink tries to control Cable set top box


I finally found a fix to this! YAY. I thought I might have to return the TV. I have the Phillips 42PFL5603D, but should work for other models.

On the TV press menu picture settings---picture---dynamic contrast (turn off) AND active control, turn off
If you have Comcast Moto box: on the Cable box go menu--->setup--->cablebox set up---RF BYbass set to ON
If you have a non-Comcast Moto Box, I'm sure there is an RF bypass setting in the menu. You'll just have to look for it. Another fix was close saying to only turn of the active control, but it took all 3 of these for it to work consistently. The latter let it work for all of 30 seconds.

I got the solution. Contact Customer Service, ask for LEVEL II Tech, and ask them for the old firmware. It will take a lot of pressuring, but they will send it to you and then it will work fine!
