SOURCE: no signal when hooked up with a digital cable box

I had the same problem and had the cable guy out and everything thinking it was my box. I figured it out by myself here is what i did to fix it. I have the vizio 32 inch hooked to an hdmi cable and through the cable box i had the aspect ratio on 1080i and i should have had it on 720p once I switched it I havent had the problem since.

SOURCE: my LG tv shows no signal with hdmi cable to hp

First you need to state Mac G5 model and MacOS 10.?,? and whether the connection is VGA or mini-DVI. (I'm at 10.5.8.) I would not be helped by LG model other than to know if it is HD 1080 or 720. I'm going to assume you have MacOS 10.4 or later but most should apply. Apple>>About This Mac>>More info...>>Hardware>>Graphics/Display and read more about the display. Digital connection will give you more info. Close the Info but even with VGA you should be able to go to Apple>>System Preferences...>>Displays and have 2 windows--1 for the built-in and 1 for the external. If the latter is off screen, press Gather Windows. On the external display Turn on Show Displays in Menu Bar. This will let you control Mirroring and Resolution. You will need to pick a resolution your TV can do 1920x1080 1280x720 or possibly less to get started. My MacBook has all of those. I usually do not use mirroring and 1920x1080 gives a good pixel match to my DLP. On the external, turn on overscan if you need to put the menu bar on the screen or off if showing maximum of photos. You need to sync first, then play with other things. -Ken

SOURCE: "No signal" sign on TV screen using HDMI selector

it sounds like a refresh issue, double check you selector and make sure it fits the refresh of the tv. i had this once with a sharp where the tv was 120hz and the selector was 60 and it created a no signal and when it did come in it was jumpy. if you have a 120 tv then selector should be the same.

Your plasma TV has a power supply 6709900019A. These power supplies failed due to defective capacitors. See the picture below and check the capacitors mark with the red lines. There are 10 capacitors that should be replaced even if they do not show signs of bulging/swelling on top.
The value of the capacitors is 3300uF/10V but you can use 25 volts as long as they fit in the space provided by design.

We have a TV LG 55la620t-da problem


Many of these newer tvs have problems with capacitors that go bad before anything else. I too have had this problem and was able to find online someone who knew which capacitors to change, after I changed the two small capacitors the set worked fine and still is. So I would search your model # for this fix in some of the repair forums out there.

LG tv flickers really badly for 10 minutes but not on all channels. It works OK with DVD. Any ideas please before I go buy a new TV. We do use a Free sat box.


You have really ruled OUT THE TV. Set is not smart enough to only have the issue on certain channels---consider if using a box for signal routing it to one of the rear audio/video inputs especially if the tv sets now getting signal via a coax/cable fitting---the box if used would be suspect number two.

No hd signal on my lg32lc5dc tv


Answer a few questions to try to resolve this issue:

What is signal source for HD you are using? (cable box, sat box, receiver in line, antenna).

Where on the set are you connected? (HDMI, HD component input on rear or?)

Does if not a box used the set have a built in HD tuner?

We have a LG42lx6500. when you turn it on after being off for a few hours the picture colour is distorted for a couple of minutes before correcting. At times you can see the individual pixels. Sometimes...


Hello

Make sure TV is on the correct channel or input. Check the cables for correct routing from TV to any other devices. Check cables to ensure they are tight and secure.

An analog signal converted to high defintion resolution will cause lines, blurriness or fuzziness in the picture. Change the resolution to a lower or native setting using the media device (cable box, DVD,). This may be an issue that requires a service call to cable provider.

A problem on one channel may just be a error on that channel. If using an antenna, it might need to be adjusted in order to ensure good signal strength. For digtal channels, go into TV Menu. Check the DTV signal. Weak signal can cause picture distortion.

If another device is being used such as a cable box, DVD player or VCR switch between devices and test picture. Check routing of cables that are used to control the image. This should be a series of red, white and yellow cables.

If a VCR with a cable box, make sure the VCR and TV are set to the correct channels for video signal to pass through. If problem is still occuring, try another set of cables. bad cables can cause picture distortion.

Bad cables can cause picture distortion as well. Try another set of cables. If picture is better than when using the cables replaced, this was the issue. If cables are not an issue TV may require service.

Hi just got a LG dvd/vcr Model RC897T. I have it hocked up right, but i can't get it to switch over so that it would be seen on the TV. can you help


If a cable box is not required for cable signal reception, connect the cable line to the ANT. IN connector on the recorder.
If a cable box is required for cable signal reception, connect the cable line to the IN connector of the cable box. Connect a coaxial cable from the OUT connector of the cable box to the ANT. IN connector of the recorder.
To view or record a CATV channel:
  1. Tune the TV to the Recorder output channel (CH 3 or 4).
  2. Set the Recorder channel selector to the cable output channel. (Example: CH3).
  3. Select a channel using the cable converter.
With this connection, you cannot record one program while viewing another.If you are using a cable box to tune channels, it is not necessary to do Auto Channel Set.

No remote (LG or otherwise) works


The remote receiver in the TV set, or its associated circuits inside the TV are not working. This would be fully proven by trying another known working remote on the TV set.

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...

When ever the picture freezes intermittendly the problem is usually poor connection on the signal line (antenna or connection on tv) or poor reception. Could be the tuner if the tv has one.To eliminate the tuner possibility try anther tv set if possible.
If you still cannot figure out the problem,let me know what kind of set up you have connected to your tv set.
Do you have a satellite or cable box and if you have splitters.
