Projection TVthe screen went to a 3d mode - 2_bing.gif sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenitthe screen went to a 3d mode - 2_bing.gif"http://i.fixya.net/uploads/images/2_bing.gif" alt="2_bing.gif" class="h_mi" />, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....

  • Screen looks 3D2_bing.gif
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This isthe screen went to a 3d mode - 2_bing.gifproblem.

Note: If you TV has as flash2_bing.gif focus or magic focus button only try pressing the button. If it fails to fix the convergenthe screen went to a 3d mode - 93a1209.pngd to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

My 47 inch vizio 3dtv has issues with the 3d. There are two images and neither are in 3d. The glasses don't work.


You have to put the TV into 3D mode to view it by pressing the 3D button on the remote. Before you press that button, look at the screen... if you see two images side by side, then you would choose SBS... if the images are one on top of the other, then it is the over/under mode, or with Vizio,Top/Bottom option which is the "TB" icon. Once you have chosen this, the screen will inform you to put on your 3D Glasses.

Just bought a 3d tv and 3d blu ray but when I put a 3d movie in to watch this screen came up and said this disc has recognised that your player and/or display does not support 3d playback. Have I missed...


You have to put the TV in 3D mode and some of the Blue ray players have to change the setting also check the owners manual for how to change to 3D mode
