I'm know somebody who has a 2003 Mitsubishi wt-42311 42" rear projection TV that they are selling for $300. During the move from Cali >NY the top of the cabinet was damaged. It looks like the movers stacked boxes on top of one corner of the TV and it was squished a bit. The actual damage to the cabinet is minimal. It almost appears as if the cabinet melted a bit. It is not cracked or punctured in any way.
When the TV is on the picture is out of alignment on the corner with the damage. The picture on the left side is about 1 inch lower then the picture on the right. The picture on the right is also slightly lower then it should be I think. Subtitles or scrolling text are difficult to read. Is this something that can be adjusted back relatively easily (and cheaply)?
i have a sony projection tv, all of a sudden my picture is not aligned. it looks like there is a red shadow. why would this occur and how can i fix it. i have presses the auto alignment button but the problem still persists....pls help, any info would be great

Ur tv still have picture,just have convergence problems wright?This tv is fixable,the tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.Replaced all these parts on the tv convergence board,will solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.
All old DLP tvs have a common design flaw,any time this could happen during the tv existing life,the tv problems is call 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 board have dead 2 STK convergence ICS and some or all of it resistors too.This parts on the tv convergence board,must me replaced,to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html
Have you checked your convergence correction Amplifiers? These usually go bad. I believe they are the STK392-XXX (XXX stands for the last 3 digits) Mitsubishi uses the 500 series,They should be replaced with new ones and the bias resistors need to be changed also.
There are many other sites that can help you install the ICs but this one is very accurate.
If you need any help in removing and replacing the ICs let me know and I will be able to walk you through the process(be prepared to take picture to help me see what you are looking at so I can help faster.
