About a 1/4 of the left hand side is a bit blurry

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

My Picture is clear in the middle but is blurry on both sides ?

Sounds like a "filter capacitor" in your power supply. This is probably the largest capacitor on the main board and should be near where the power cord enters into the tv. A capacitor is round and tall, sort of like a miniature cattle farmers grain bin. Take it out and order a new one. You will need to write down two things: the voltage rating and the number of microfarads denoted by the symbol "u". For example, a "2500u at 250 volts. It will have two pins soldered into the board. Desolder, remove, and replace and resolder. Keever
