Question about Panasonic Projection Televisions
After recently moving our panasonic xf series projection tv, the colors inside are not aligned. How do you align the colors?

It sounds to me like the convergence amps themselves have failed. Ic7001 and Ic7002, both are STK392-110 Sanyo built Ic's and not an expensive job for a qualified shop. When shopping around for a shop to repair it ask what they charge for replacement of the convergence amps in this unit. And take the unit to them to save pickup and delivery charges...
Have a great day!

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.

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!
