Clear picture is gone looks like watching a 3-d movie without glasses

When watching TV, the picture changes to 3-d like colour only green and red in separate layers. Turn off for 5 mins and is ok again. Becoming more frequent each day. Don't have instruction book. Could it be alignment or one of the lamps burning out?

Sorry i am new at this but have had the same problem with a toshiba and it was the IC chips which control the converigence which is lining the colors back up

or it just may be as simple as converiging the colors in your case if you have not trided to yet

Hi,
The problem is your convergence circuit board gone bad. This is commonly caused by shorted/open IC on that board. First try to spot if there is a bad solder joints and resolder it. If nothing replaced the convergence IC. Also check the resistors around.
Hope it may help you.
Have a nice day!
Thanks for using Fixya.

Hooked up PS3 to system and when watching DVD's the right side of the picture is blurry and appears doubled, like an old 3D movie without the red and blue glasses. When watching TV everything looks fine.


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV 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. In some cases the TV will also not show any video. 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.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • 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. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Turned on tv and it looked like 3d. Found red horizontal convergence lines extremely bowed. Cannot correct with magic focus either in auto or manual. What is the fix and what is more cost effective ......


TAKE OFF THE FRONT PANEL AND FIND THE FOCAS ELECTRONIC FOCAS CONTROLS. USUALY BETWEEN THE LEFT SPEAKER AND THE FIRST CRT GUN. PAUSE A DVD WHEN THE CREDITS GOING. OR USE A MENU IN YOUR SAT RECEIVER TO LOOK AT. USEING THE GRID IN THE TV SOMTIMES IS NOT ACCURATE. YOU WILL SEE 6 SMALL KNOBS (RED,GREEN,BLUE)FOCUS AND(RED,GREEN,BLUE)SCREEN DRIVE .FOLLOW THESE STEPS 1 TURNDOWN RED AND BLUE SCREENDRIVE 2 FOCUS THE GREEN (YOU SHOULD SEE SCANLINES) 3 TURN DOWN THE GREEN SCREENDRIVE 4 TURN UP THE RED SD UNTILL YOU SEE RETRACE LINES THEN BACK IT OFF TILL THEY ARE GONE. 5 FOCUS RED (UNTILL YOU SEE SCANLINES) 6 TURN RED DOWN AND TURN UP BLUE 7 FOCUS BLUE (BLUE WILL NOT BE AS GOOD AS RED+GREEN NOW YOU ARE IN FOCUS, NOW YOU NEED TO GET SCREENDRIVE BACK THE BEST WAY IS TO, PAUSE A DVD ON A BLACK SCREEN SELECT PLAY MOVIE AND HIT PAUSE RIGHT AFTER . TURN ALL THE LIGHTS OFF IN THE ROOM AND USE A SMALL FLASHLIGHT TO ADJUST SCREENDRIVE SO YOU DONT MOVE FOCAS BY MISTAKE. THE TRICK IS TO END UP WITH A VERY FAINT GRAY SCREEN WITH EACH COLOR UP AS FAR AS YOU CAN WITHOUT SEEING ANY COLOR ON THE TV. WHEN YOU GET THIS TRY PLAYING THE MOVIE. MAKE SURE THE BRIGHTNESS AND CONTRAST IN THE TV ARE AT A NORMAL LEVEL BEFORE YOU START . COLOR,BRIGHTNESS,AND FOCUS IS NOW SET TO YOUR DVD PLAYER.DO A FINAL CONVERGANCE AND YOU ARE DONE!
IF YOU CAN'T GET A COLOR TO FOCUS YOU MAY HAVE TO DO THIS MANUALY. SOME TV'S YOU CAN LOOSEN THE NUT ON THE CRT LENS AND MANUALY FOCUS IT. (LIKE AN OLD CAMERA). IF YOU GET THIS FAR YOU MIGHT AS WELL CLEAN THE LENS WITH A VINEGER BASED GLASS CLEANER (SPRAY THE RAG NOT THE TV) TAKE A LOOK AT THE MIROR, CLEAN IF NEEDED. IF THE MIRROR IS REAL DIRTY THEN THE SCREEN MUST BE BAD TOO.TAKE THE SCREEN OFF AND CLEAN THE BACK SIDE IF NEEDED. LOOK INTO THE LENS AT THE PICTURE TUBE YOU SHOULD SEE A NICE BRIGHT CLEAN PICTURE IF IT LOOKS CLOUDY YOU NEED TO CHANGE THE LIQUID IN THE CRT GUNS.I DON,T THINK YOU WAN'T TO TRY THIS YOURSELF. TIP(I USE A LITTLE ARMOR ALL WHEN I CLEAN LENES, THIS REPELS DUST LIKE IN YOUR CAR) IF YOU CHANGE YOUR FLUID AND WANT TO KNOW WHERE TO GET NEW FLUID I PUT CLEAR ANTIFREEZE IN MY PIONEER TV 3YEARS AGO AND STILL LOOKS GREAT "NOT KIDING" HOPE ALL THIS YOU. IF YOU ARE NOT COMFORTABLE TO DO IT. HAVE IR SERVICE. REPAIRING THIS WILL BE YOUR BEST OPTION>THANKS

Picture looks like 3D without 3D glasses on???


The cost I don't know, but this can be fixed. I'd say shop around a bit. Make sure the repair person is certified for your TV's manufacturer. There are generally 3 lamps in projection T.V.'s, Red, Green, and Blue. They have to be aligned for the TV to project a clear picture. A credible TV repairman should be able to fix it. Depending on if it's new enough to be under warranty they may cover it as well. Really the only reason to get rid of it is if you want to get a new TV anyway. Depends on the cost of having the lamps aligned.
