Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

Samsung hcm4216 rear projection

I have a blue shadow/bar across the top and arching half way down the set, Ive researched other projecion tv's and found that the blue convergence board seemed to be the problem. I've checked my model and i dont see convergence boards. On the list, there is a (picture tube for blue). Does that sound like what I need? It's $271.00 Is it resonably easy to replace? thanks. Dan. p.s. here's the parts list for my model http://www.samsungparts.com/search/search.asp

Green hazy upside down arch of color across the screen

Your convergence board is in need of reworking on a component level or replacing the board! And you will most undoubtedly need to resolder the vertical IC and all ICs mounted on heatsinks on the power supply board. This TV is showing its age. You may choose to repair and that may last a year more or so! Good Luck and thank you for asking!

It is failure of convergence ICs and these two ICs will be replaced on D board.
If you are comfortable with TV repair and know good soldering skills then can do the job easily.
Convergence ICs are mounted with sliver heat-sink on D Board of TV and part number will start with letter STK...

Need to replace the convergence IC in the green vertical circuit. Check the 3.9 ohm resistors located in front of the IC.

One of the convergence output IC's has stopped working and needs to be replaced. If the IC shorts out then it will draw too much current and possibly blow a fuse, and the set will shut down to protect itself. The IC should be replaced and the set realigned by someone with experience in convergence circuits.

The audio on my Samsung TV does not work. I took it apart and checked the speakers, which work fine. I've tried using the remotes buttons, TV buttons, Pressing mute/un-mute, plugging in a DVD player to tryaudio on input/av1/av2, also I didn't mess with it for a couple months hoping it would magically work. What more possible resolutions or tricks are there to try? 42in., rear projection TV, silver, and it is a Samsung Model# : HCN4226W. The quicker i can get some help the better because I would hate throwing it away.... Thank You
