I have a Sony TV (KV32XBR95S). Lately i noticed that the picture is crookit and it is very noticeable especially when there is a square image (example scoreboards from any sports which is normally square). When this square image or any straight vertical line appears in my tv you will notice that it is leaning on the left side> I wonder if anybody can help me with this problem. Thanks!

Good Afternoon, side a:
Sounds like Sony's Quality Control was asleep when your set went down the line.
The problem is the deflection transformer on the neck of the picture tube is not aligned properly. This is an easy fix if you feel up to taking the back off the set.
When you get the back off the set, look at the neck of the picture tube and you will see a rather large device and some circuit boards attached to the neck of the picture tube. ALWAYS REMEMBER THE NECK OF A PICTURE TUBE IS FRAGILE SO DO NOT BANG IT OR DISTRESS IT IN ANY WAY.
This device is the deflection transformer (or, commonly known as the Yoke). It is clamped on that fragile glass neck of the picture tube with a form of screw clamp. You can loosen this clamp and rotate the assembly slightly clockwise or counter-clockwise to straighten up the picture.
UNDER NO CIRCUMSTANCES MOVE THE ASSEMBLY FORWARD OR BACKWARD ON THE NECK OF THE PICTURE TUBE. This would cause you color problems beyond your wildest dreams.
Another hint: this deflection transformer carries some pretty hefty voltages that range from 6000 to 10,000 volts.
You're pretty safe from encountering this voltage, but, a careless touch could be a shocking experience. Put on a pair of your wife's latex gloves (the ones she uses for cleaning the oven and such) and touch only those pieces covered with insulating materials such as plastic.
Another hint: a little movement of the yoke equates to a lot of adjustment. Make only minor movements.
Tighten up the clamp on the beast and put the back on the set. You're good to go again. This is a mechanical adjustment and once made should never have to be addressed again during the life of the set.
