I have a 65" Mitsubishi TV. The screen started to look out of focus and the color was off. At the bottom of the screen it has an ark or a curve look to it. It used to happen once in a while and clear up on it's own. Now it stays that way most of the time. I tried to adjust the convergence with no luck. The convergence would only adjust left and right not top and bottom.

You have a convergence problem,all this sets show this problem sooner or later,you have 2 or 3 amps for the red,green blue colors and this amps go bad and need to be replaced then you have to do a convergence aligment from the service mode and not form the customer controls,a qualified tech should be able to correct the problem since is a common one.

You lost your convergence IC's and possibly a resister or two that are in the same circuit. If you are good at Soldering, this should be somewhat of an easy fix. I believe you can still get the IC's for this set.
The tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board is dead.The tv convergence board reqiured changes it 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board problems to solved the tv picture convergence picture problems.The shop,will cost like $300-350 for parts and labors.
In your On Screen Display menu (OSD), you should have a place that says "convergence". As a sub heading to this it will say "Auto-Convergence". This is where you want to be! Hit OK under AUTO, and watch the magic happen! If your set happens NOT to have AUTO, you'll have to do it manually. You're going to make the lines all match up doing one color at a time until all three colors are done! It's not hard at all. It may take a little patience at first, but just think of all the money your saving by not having a TV tech come out to your house and you'll be fine!
It sounds like your TV is experiencing a CONVERGENCE CIRCUIT failure. YES, it is worth repairing, it's a great TV. The cost will be from $450.00 to $650.00; call an Authorized Service Center and have them give you an estimate B4 repair. Good luck, big IRISH. PS: It's Not An Easy repair to do your self.
Use the Setup menu to select English or Spanish as the language for the menus and on-screen displays. Adjust Color Balance Automatically or manually (PerfectColor TM) using six colors, Magenta, Red, Yellow, Green, Cyan and Blue. Reset the Color Balance to the factory default settings. Align the focus (convergence) of the TV's projected light beams or reset the focus to the factory default settings.
