You need to replace the two STK-392-560 CONVERGENCE IC chips this set uses.

This may be a do it yourself job if you have some skills, if not most shops charge a lot for this kind of repair.

Let me know if you have questions or need advice-I am here to help.

    Hi, I think I have similar problem and I am about to try to replace the convergence IC. So I opened up the TV and I try to figure out what it takes to take the circuit board out. Everything seems ok except that there is a thick red wire (more like a small tube) connecting to a big plastic device on the board. Can I pull it out. I seems tightly connected and I do not want to break anything.

    please help

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

Color is mostly yellow and blue with double images


you have lost the convergence IC`s in your set, this really isn`t a diy repair unless you are very proficient in un-soldering and re-soldering components, once replaced there will be an alignment procedure as well that will require the service manual also, if you have more questions feel free to ask away, video-tek

Double Images


Just click below for convergence repair kit;

http://servicemanuals.vstore.ca/

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

Yellow vertical bar on right edge of screen


Your set is starting to get a convergence problem and the only way to repair it is by changing the convergence IC's,(3)one for each color,the blue migh be showing more now but soon all 3 colors will be out of alignment and you will not be able to correct it with the custumer controls,is great that it has worked for so long without this problem,if you are familiar with tv service you have a place to check but if you are not too familiar be safe and call for help from a pro-servicer.Let Us know how it goes.
