Samsung HCN4727W Rear Projection TV, green screen, audio works

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Toshiba TP50G50 Theaterview picture is double with red color only

Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

If the CRT Projection television has several colors or one that arent lining up, if due to an impact - you may have a broken mirror, if just happened all by itsself it may be a convergence issue, either issue is repairable, probably for around $400-$500. I dont recommend taking a set like that into the shop as sometimes transport can break/crack a mirror or throw convergence off.
