I haven't tried replacing the above parts because still searching for the best solution. so please email me if you have your set fixed and how. thanks Arv

SOURCE: SONY KP-57HW40 TUNS OFF AND STANDBY LIGHT BLINKS 6 TIMES

6 blinks is usually associated with failure of the horizontal deflection amplifier - which shuts down the high voltage system as well.

The repair requires testing to determine the exact parts that have failed. There are, for example, a few hundred parts and a section of the Jungle IC chip involved. So, repairs could require something as simple as replacing some inexpensive passive components OR as complicated as replacing the jungle chip (very expensive).

most of the time it's the horz. transformer and transistor.

SOURCE: Blue Screen and TV shuts off

Here's a shortcut to what the blinking codes mean.
http://www.somelifeblog.com/2007/08/sony-tv-led-blinking-codes-what-does-it.html
Strange how some people have 5 blinks. Most with this problem have 8 blinks (like myself)

I still have the blue-flash-then-shutting-off problem.. (8 blinks meaning voltage error) but I did fix the blue lines.. The lines across the screen can be very easily fixed whether they're blue green or red. . No, I mean REALLY easy. Took me longer to get the cover off. Once the front cover is off it takes 10 seconds. This link was also posted recently in one of the posts below as a solution..
http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
(My lines didn't look like the ones in the picture mine were several evenly spaced blue arcs)

After some research I believe the flash/shutting off problem means the CRT is going. I've also read that it might be the D-board and I'm not even sure that that is... But If it is indeed the CRT then I'll let you know it's very difficult to find a replacement blue CRT as this part has been discontinued.. but I did eventually find an alternate to an alternate part (yes that's the 3rd alternate !)) online for $256. Here: http://store.tv-repair-service-salinas.com/8-733-649-35.html

If you're bold enough to attempt that then good luck and please let us know if it worked.
Or another alternative is there's a whole lot of Boxing Day sales goin' on right now.

I have a Sony Color Rear Video Projector Model KP-57HW40. Its blue color is not working anymore and noticed some burn smell by the set which controls such blue color.


It may be the CRT drive board which is attached to the bottom of the Blue CRT. I would check that Board for signs of being burnt it may need to be replaced.
