My tv suddenly has decided to separate the colors and the right and left edges are curving in. On a show it looks like the red and green are separated, but on the channel guide, which is blue and white, those colors are separated. Its almost like a shadowing of one color of the other. Can you help me?

Your flyback has failed most likely...bad new is they are nearly impossible to find, This is a known issue on most of the models below. The site Tv Repair Kits can sometimes get replacements - but its not often.
This repair kit is known to work on Magnavox TV sets with the following Chassis/Model Numbers.
I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.
The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).
What you have there is a PTV835 chassis and the convergence amps are two STK392-110 Sanyo built Ics mounted on a large aluminum heatsink on the signal board... It could very well be the amps and it could also be the protect fuse 1008 (2a 250v), fuse 1007 (1a 250v) and a 1a mylar cap at location 2055, all of those are located on the upright digital convergence board.
This is not an easy job in this particular unit and not one that I could write-out in a step-by-step set of instructions, too many varibles. The short version would be to strongly suggest that you take this to a qualified shop and have them do it..
I would also suggest that you ask them to replace the amps with the STK392-150's for greater reliability. In fact you could purchase them yourself from acme in Florida and save a few bucks. Also, take the unit to them don't pay the pickup delivery and you'll save a little and always get a written estimate first before any work is done...
Hope this helps!
PS: A job like this in my shop is approximately 425 - 500 dollars plus tax including parts.
