Problem with my Samsung PCN5425R 54 in. projection. I am seeing double and pictured is bowed and I see red and green colors on the screen. Is this the convergence board. Is this difficult to fix? I am not...


Your convergence ic’s have failed, this is a common problem with most all projection tv’s, the repair is involved. I suggest in your case calling a local repair shop.

Picture is bending at the top and bottom and looks 3d


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. 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, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links 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 - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

Red and green wavy lines


If the distortion that you see can be described as somewhat of a 3-D picture, the problem is teh convergence circuit and this can be fixed easily. Also, if you can solder, you can fix this yourself. If you wish to do this, please update this and I'll provide you with some instructions.

RED AND GREEN DOUBLE AND BLUR PICTURE HELP PLEASE


You have a convergence problem. Components are shorted out and must be replaced. Unless you're a technician, there's really nothing you can do at this point.

Do you mean that at the top of the picture, the red color has shifted downward, bowed towards the center? If that is what you see, one color suddenly bows toward the center on any side of the picture, then it means that one of your convergence IC's has burned out and needs to be replaced. It is a good idea to go ahead and replace both STK392-110 IC's with the newer improved STK392-150's. If you have never replaced convergence IC's and realigned the convergence circuits in a projection TV then allow a qualified tech to handle it for you.

Convergence Problem?


Convergence problems are what you have possibly a pincushion error. Either way if you have to have a repair shop do the repair, you should look at replacing the old TV.
