All of a sudden the top of my TV picture went pink and green, pink and green colors over lap and make it look blurred. Tried aligning colors but green on graph are wavey.

Most common cause for this on the Sony KDL 40EX520 is that the connections to the screen across the top edge of the panel become loose causing blurred picture, mis-aligned colors etc. The Fix requires dis-assembly (Removal of the entire case) and re-seating/resecuring the connection across the top of the LCD Panel.
There is a pretty detailed video of the process (less the disassembly) here: https://www.youtube.com/watch?v=80PfZXFGDvQ

The colors tell me of a convergence IC issue, warped bottom and top tell of another.

see this page on reparing the convergence problem yourself

also compair the before and after pictures to see if this is the other problem your having.

Then you have another fault, which im not completely sure of right now. I will look into it.

repair your tv by tv technician it may have picture tube problem

Tv have convergence problems,it dead.Colors lines R,G,B don't aligned.The tv convergence board is dead.The 2 STK convergence ICS and some or all it resistors are dead,these parts must be replaced to solved the tv pictures covergence problems.The shop,will cost u $300-350 for parts and labors.

It sounds like one of the convergence Ic chips is bad---you will need to locate and replace both of them and look for any damaged parts around them; there usually are two pico fuses in this area, one for each IC. The fuses do not look like glass fuses--they usually are green or orange in color and will have the amperage marked on them and on the top of the circuit board.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Give this a shot.. in the front of the tv when the access panel is off to where you can see the tubes. look off to the right and you will see a set of 6 small black knobs. The top knobs are for color the bottom knobs are BLUR.. turn those and see if they will help. ~Matt~

Good day.
Your unit is still worth. It may be a caused of loose contacts along the circuitry. It can be remedied by resoldering the terminals particularly the chroma section and the crt circuit.

The most likely cause is shorted convergence chips and possibly a few pico fuses.
