Find someone that knows about TVs to take off the front access cover and adjust the screen controls .DON'T TOUCH THE FOCUS KNOBS.Just the screen control knobs.Usually they can work a few more years with adjustements . But if it can't be adjusted to work then the guns would have to be repaced.Many many many many of your model were affected by a little screw up sony made with their CRTs.

My Sony big screen rear projection TV model KP=51HW40 produced 2002 screen flashes red then shuts off. We can turn it back on and it will run for 30-60 minutes and then it repeats red flash. Is this


The Problem you are having is a Cathode to Grid Short in the Red CRT,When it Shorts the screen will Go all Bright Red and shut Down,The Best fix Would Be to Replace the Defective CRT (GUN)

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

KP-51HW40 Sony 51" Fades to blue screen


The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

Kines on Screen and Fading


Open up the front of the set by removing the speaker screen and the black piece of particle board. on the bottom right you will see 4 knobs. Turn those knobs slowly till the arcs go away. The 3 knobs on the bottom are for color. the 3 on top are for the focus.

I had the same problem with mine 2 years ago (TV was 1.5 years old at that time) I had extended warranty on TV and it was fixed by Sony at no cost to me. Now yesterday I have another problem with it. All of a sudden screen went BLUE. No Sound either. It could be the CRT (That's what I read here) Out of luck this time. Will call local Repair shop (70 miles away) and see how much it will cost to fix it. Good luck.
