Unfortunately your best bet is to have a professional take care of it. You tried manual or auto convergence? Was there any change? If you need any help contacting a professional I will be glad to assist you.

The board may not be available, but hte defective components are. There is no reason for the service center to replace the bopard when a couple of ICs and resistors or fuses are all that are defective. The parts that are bad are large black ICs attached to a heatsink and are most likely marked STKxxx. He/.she should resolder the pins on these ICs first. That may resolve the problem. If not, replace the ICs.
Keep us posted.

I don't know why that guy told you to replace your "DC" board (that is the one you mean, right?) More likely than not, it's your convergence amp integrated circuits (ICs). I had what I think was the same problem (on the same exact model TV) you described, and I looked around alot of blogs and DIY websites, and this seems to be the most prevalent root behind these convergence problems. I ordered the two chips for twelve bucks (for both), spent a few extra bucks (like $35) on some electronic tools / solder supplies, and followed procedures laid out here at http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-i.html, as well as paying strict attention to the service repair manual (which you said you already have?). The result? No more convergence problem, and I saved myself around $400 - $550 over having it done by a professional.
Seriously-- I bet this is the culprit. Just make sure if you're gonna do this that you FIRST check the six resistors (located at spots D-7011 thru D-7016) to make sure there are none burnt out / opened. It may be that one of those is fried also / instead. Since they are far easier to replace, it's good just to rule them out first.
And by the way, just FIY, when I did this I had kept the TV unplugged for about two weeks first, cuz I wanted to make sure all the capacitors were discharged and safe. Did I need that much time? Maybe not (some have said a few hours is sufficient), but I was also primarily concerned about the Flyback Transformer and its wires, which have the highest voltage (up to 30,000 volts) and can hold a charge pretty long. And I'm still here to write about it. So, check out the link, and see if you'd like to try this yourself, as well!
