Samsung HC-P4241W Convergance problem

I have a Samsung HC-P4241W with a big convergance problem. I changed both STK 394-250 ic's and the convergance is still off. I tried the "self focus" button and still the same problem. I would like to do a manual convergance and align everything my self but I can not figure out how to do so. Can anyone help me with this problem? Thank you

Press mute 183, if it isn't 183 it's 138.   You will see a large grid which you get the fun of adjusting, it's tedious as all get out! Enjoy!

Your Convergence output is burnt.DONT turn that TV on until convergence IC's are replaced,orange glowing inside that you see it is resistors that overheating and burning.Unplug TV from outlet before more damage is done

The colors are all messed up. Everything is yellowed with a blue double behind it. The screen is preaty dark on the sides and lighter in the middle?


Thanks for using FixYa.The issue is with the failed convergence (STK) ICs which needs to be replaced. It's not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you'll have to open the back of the unit and then replace the ICs (STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime.
There are repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please rate the solution if the issue is resolved or post a comment for further assistance.

Samsung HC-P4252W convergence problem

You need to change the convergence ICs. This is an inexpensive repair if you do the repair yourself. The ICs are located on the big heatsink they should Be STK392-110 or 120 or else they could be STK 392-010 or 020 . But what ever STK number you have you will need to replace both. Here is a link where you can get replacement ICs and they include step by step installation instructions with the new ICs. Here is their link.
