The screen is green and the tint option in the menu cannot be adjusted.


This symptom usually indicates CRT failure. Projection TV's, especially older types use 3 CRT "guns" to project the image on the screen. One is Cyan or Red, one is Green and one is Blue. If the Red and Blue become weak or do not project, the Green gun overpowers the output of the other two. These three "guns" are aligned exactly on top of each other so when all three are correctly functioning, the correct colors are projected on the screen.

Green line on left side of an image and a red line on right. Such as around a face. Colors just don't line up and picture is very fuzzy. Had another old rear projection and it had a way to align it. Can...


Your other model was more than likely a CRT projector where you coulod manually align the Red/Green/Blue guns. The one you have now is more than likely an LCD projector which can't be readily aligned. Sounds like the panel is failing.

Red color convergence issue; Red lines are curved


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

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

I have the mitsubishi 55711,i have a double image


This is a V-21 Chassis common, with these symptoms, for failure of the convergence amps. This set uses two STK 392-110 Sanyo amps mounted on a heat sink and hard to miss. They're a 40 pin ic about the size of a half pack of cigarettes.
It has also been my experience that two or more of the yoke return resistors need to be replaced, most commonly R8c21 and R8c22, both are 3.9 ohm 1w but test all of them for reliability.
Hope this helps!

Red and green have separated. is this fixable?


yes this can be fixed
it is the convergence IC's that controls each color image alignment ,also other components(resistors , diodes , capacitors , ect..) in circuit with these convergence IC's(STK's) also need testing to see what other component has also failed or needs replacing.
