Samsung HCN4226WX convergence problem

Hi, I am getting a bowing from top and bottom and a ghosting affect in the middle of the screen. I think the convergence board was changed once about two years ago. I am pretty sure its this board again. First let me say thanks for posting so much useful information.
Are there any distributors in Canada I can buy the board from?
And I seem to see two different part numbers for the board;
BP95-00142E which on the Samsung parts site does not refernce the HCN4226WX model
and BP94-00155A which I could not find on the Samsung site, but on the partstore site shows a description as an amp.

Which number should I order?

Please & thank you

My 57hx81 has a slight concave bow in the middle top to bottom


Sounds like a problem in the vertical sweep circuit. Check voltages to your convergence ICs. If they are  not to spec then look for bad fuses and capacitors on the power board. These will throw off the DC voltage to the convergence chips causing the bow effect. I've had a single bad pico fuse ($1) cause this symptom.

Bowing screen


You have bad convergence ic's. You can take the convergence board out yourself and take the part to a repair man to have him replace the ic's. I've had it done twice on my tv, it cost about 200 bucks.

Blue convergence problem


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with 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 - 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

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Yes, your geometry correction has failed and you will need to seek qualified tech for help. You need what are called STKs and you should be able to get the job done inhome for under 300.00

I'm not a 100% positive this would fix your TV, but I found the convergence board on PartStore.com for about $80. Hope this helps.

One of your convergence IC's has either cracked loose or burned out. The IC will have to be resoldered or replaced and then the convergence circuits realigned. If you do not have experience in repairing convergence circuits then have a qualified tech handle it for you. This is by far the most common failure in the projection sets and a good tech can have it fixed in about an hour and a half. I charge $150 for that but shops in your area will vary, so call around.

3d/rainbow affect


Sorry to tell ya Gemini, but there are no user serviceable parts inside a TV set unless your a technician as theres several safety issues of Hi Voltage involved as well as unsoldering and soldering. You Have a convergence problem or Pincussion issue with your set. No quick fix for this one. You need to call in a pro to assist you with this repair. Good Luck
