    I have a similar problem on my Samsung PCN5425R. The picture is not terrible but the auto convergence (Perfect Focus) stops at 37% cpmplete. I also noticed that the "white level" on this set is substantilly more yellow than my new Hi Res LCD TV.



    Is there a problem with the Samsung projection TV with its yellow color or are my expectations just too high relative to an LCD?

Perfect focus functions are based on service mode setup...or factory settings. if the alignment of these setting are loss then the unit wont perfect focus. does the unit have a complete loss of convergence. a complete loss of convergence indicate possible failure of convergence amps.

Samsung HCN5529W 55in Rear Projection can't Perfect Focus


hello What you have is a convergence problem. There is 2 modules inside your set that aligns the colors to have the same geometry and superposed . It is a common problem in rear projection tvs ,
You don`t have to worry about your blue tube , i`m sure it is perfectly fine, it just needs to be aligned through the convergence circuit.
Most often the problem is with those convergence modules that are faulty and need to be replaced.
Hope this will help good luck

"Perfect Focus" problem on Samsung HCN4727W


You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Screen is bowed on top and bottom.


Projection sets have two very common problems outlined below.

The first common problem is convergence

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. The TV can also shut down when the convergence starts to fail.

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,Mitsubishi,Zenith, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

Perfect Focus 2


Use a site like servicemanuals.com and get the service literature for your make/model.Do NOT perform factory reset procedure-that is reserved for when certain parts are changed.You will need the access sequence,adjust info and add to memory step for servicer convergence.Keep in mind--you may have defective convergence IC's.If so,you will have difficulty w/alignment.Use OEM or better IC's no generics!! They won't hold up.

Perfect Focus


Perfect "FOCUS" is a misnomer.Convergence is the real issue.Enter servicer mode--perform accurate convergence alignment procedure--activate perfect focus as last step to 100% alignment.If you have a High-Definition source,check procedure for that.

Samsung 54" rear projection PCL5415R Won't Turn On


Although I am not incredibly familiar with your model, There is most likely a small board mounted above the others near the crts, there is a small red connector with a blue wire if you unhook it it will remove power from the convergence IC's and if they are shorted it might come up with conv out, will need a new module.
