It is convergence problem in your tv you need to replace the convergence IC .

The convergence setting is not proper in your tv . You need to access convergence setting through service menu .

You can reduce the g2 for the blue tube
open the front grill and open the 4 screws hold the resister block
to have acess to the register block.
Then there should be the black box have 6 knobs
the one call for Blue g2 not the focus block.
Adjust it counterclockwise a little bit
and try turn on TV again

Picture comes on then fades to blue


Check the info from this website to see if you are able to fix your TV. You should turn the blue screen control down slightly counterclockwise. If that did not work, then more likely you have a video amplifier IC defective or a blue CRT.

Blue screen


This is easy to fix, pull off the front grill and turn the bottom left trim pot anti clockwise until the picture comes back. I am asuming the picture there and then it fades to blue. There is a step by step instruction on how to get the whole thing apart http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

Sony KP-51HW40 51 in. Rear Projection turns blue


Hello......
First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.

you are experiencing one or more of three things
1.the crt itself is damaged
2. the vertical ic on blue crt board is bad
3. the focus block is bad
if you hire a sony authorized technician they should be well aware of this problem.
