Very common problem on your model. you have a bad blue tube. in order to repair it you will need to replace the blue tube and then aligned it to the others. you will need to know a little about what you are doing. if you are interested in doing this yourself i will need a serial number off the back of the set to get you the right part number for the tube. This tube is going to cost you somewhere between $200-$300. To get this tube in there and looking right is a little of a fine art, I can walk you through this though. Let me know what you want to do!

Tv screen turns blue and shut off. The red LED light flashes 9 times there after that.


The blue CRT has shorted and will need to be replaced. You should be able to get a replacement blue CRT from www.tvrepairworld.com

I have a kp57hw40 sony tv and the scren it flashs


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...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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
