LG RZ20LA70 - black screen

Hi, when i power on this screen, and i cycle through the AV and other inputs, im getting a black screen...however the blue box in the top right hand corner that shows the channel name is showing ok..and also the black/white fuzzy screen appears on one of the channels, but then goes back to black. When i select MENU, if i look real close, i can just make out the menu options......any ideas?

Thanks

Stephen

It's possible there is a flaw with your TV but more likely the listing information is being blocked. Many cable companies do this, likely another reason to force you into buy/leasing their equipment. This should not be a problem with OTA.

It is NOT the main board. You need a V CHIP UPGRADE "epk file" Email me and I can walk you through it, very easy introspectionx2@yahoo.com Put "TV GUIDE" in the subject line

The problem started with TV GUIDE messing with things while they are doing their digital conversion

Ps3 plays in black and white with av composite cable


Some newer TVs do not have the traditional "yellow" video input, known as an "AV" connection. Even without that input, you should be able to use the standard three-color Wii AV Cable that came with the system.

What to Do:

  1. Look for "component" inputs on your TV. These connections have a row of five differently-colored inputs (green, blue, and red for video, white and red for audio). If you have more than one set of component inputs, it's the first set that generally works with standard AV cables. Look for a set that has a green input with yellow around it, or the word "video" just above or below it.
  2. Plug the yellow end of the Wii A/V cable into this green "Y" input. Plug the white end into the audio "L" and the red into the audio "R." Leave the blue and second red holes open.
  3. composite_inputs_window.png
  4. Turn on your Wii console and set your television to the input select being used.
  5. If you are seeing the image from the Wii in black and white, try the following to get the image in color:
    • Cycle through your television's input channels (usually with the "Input Select" or "Source" button on your TV's remote control) to find the input select that has the image in color.
    • If you're only finding the image in black and white, you may need to switch the setting of the input select from a component signal to a standard AV signal. This can be done by:
      • An on screen menu option. This is often accessed by using the "Menu" button on the remote.
      • A button on the remote that switches between the standard and component signals. These can be labeled such things as "AV" or "Video."

LG 37LG30 wont come on. Gives blue light, but screen stays black and no sound


Sounds like the problem could be in the power supply of the TV. Have a technican check for defective capacitors if you're not equipped to do the job yourself.

Why cant i get my wii console to work in color


Well it might either be the tv or the av cables that is causing the wii system to be in black grey and white then.

My LG E2250V-PN turns on and my Macbook goes to a blue screen, indicating that it is picking up a signal, but then nothing happens. My Mac screen never shows on my LG. Also, even if i try to press the menu...


Hi sophie,

I see you want to extend you monito to an LG external monitor.

Have you tried selecting the input PC or the input that is for the cable that you are using for the Video.

If you are using HDMI select the Input HDMI on your LG if you are using DVI then you should select the input DVI to be able to get the signal from the Laptop come out of your LG.

I hope this helps.

Have a nice day,

Im trying to set up my tv, it was given to me as a gift, my uncle was using it it works i can change the channels but when i try to work my dvd player with it, only the audio comes on the screen stays...


Hi,
Please few things...
1- Make sure audio and video wires are hooked correctly in AV input of tv and you selected that AV input in tv with its remote.
2- Also check your dvd has not been set on progressive mode if you hook dvd player through yellow-red-white wires with tv.
3- if dvd player is set on progressive mode, then hook it with tv by component video input, red-green-blue for video and red-white for audio.
Hope this info will solve your problem.
Thanks.
