Question about Sony KP-51WS500 51" Rear Projection Television
SOURCE: sony KDP57WS550 Projection tv red, green and blue virtical outlines on left and right sides
This is a convergence problem. You will need the stk's changed and a pico fuse or 2. also from looking at the pic you might want to clean the lenses and mirror after the repair to bring back some of the vibrant colors the set once had when it was new. This repair should run you anywhere from $300-$500 depending on your area and the tech that comes out. If you need more information or would like to try to fix it on your own please let me know.

SOURCE: Blue to Black screen on Sony KP-57WV600
Rowdyroddy,
Thanks you so much for this info.
I had the same problem with my Sony KW-57wv600. Blue screen turns black after a few seconds, and then standby light flashes seven times.
I called a local TV technician, and described problem. I was told it would not be cost effective to fix. After reviewing the "simple" instructions given on www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html I figured I had nothing to lose.
10 minutes to remove front panel, a "very slight" turn of a screw, and TV worked again perfectly. I could not believe it!
Thank you so much for your help!
SHAME ON SONY FOR NOT POSTING THIS FIX ON THEIR WEBSITE! SHAME ON THE TECHNICIAN AT SONY WHICH INSISTED A SERVICE TECHNICIAN WAS REQUIRED.
I have always been a fan of Sony, swearing by Sony products exclusively. After this experience, I am now forced to consider some other options when purchasing electronics in the future.

Yes common problem it seems with these. I can help you get the set working but this fix only prolongs the inevitable so I'm told. (more about that at the bottom) Please read entire posting before starting. You will need to take off the front panel, there are 2 screws towards the bottom on each side behind little pop out plugs. Once those are out take off the panel (pull from bottom, sometimes the round clips at the top come off, either glue them back on the panel or leave them out). There are wires attached to the panel, you can either unhook them or just take them out of the "twist tie" holders and move the panel out of the way to the left. You will now see a thin panel. Remove this one also. Once that is off you will see the bottoms of the 3 glass tubes and on the "floor" of the set there is a group of 6 small knobs. This is called the focus block. Each row of 3 knobs are labeled either screen or focus, also, there should be 3 letters R G B (Red Green Blue). (We won't be adjusting the focus knobs).You will need to adjust the Blue screen knob (on my set it was the bottom left knob). If the set will stay on for a little bit you can adjust it with it on. Once you have found the correct knob (don't worry about the white paint) turn the set on, once you see the picture slowly turn the blue screen knob counter clockwise until the blue diagonal disappear. Be careful not to turn this knob too fast while the set is on. Keep in mind, it may take a little bit to break off the paint. You will see the screen turn back to normal as you turn the knob. Adjust it just until the lines disappear This should solve your problem. If the set won't stay on, with it off turn the knob about 1/8 turn counter clockwise then turn the set on. Once it is on you can fine tune it. Adjust it just until the lines fade out of sight. (You may have to adjust back the other way until the lines show up and then back it off again). Remember to turn the knob slowly. I have heard people getting charged a lot of money for this. I was also told that this is compensating for a dying component(s) all I know it has bought me at least a year. I also read that someone has gotten several years out of there set w/o repair just by doing this adjustment whenever its needed. (once the lines start presenting themselves). I can't see spending big money on these sets when you could put it towards a new set so I will keep it going for free as long as I can. I hope this works out for you. I'm tired of typing so good luck and post if you need any more help. BTW this adjustment works if this symptom presents itself in green or red also. Just substitute the blue knob to the applicable color. Now go put your TV back together :)

SOURCE: Screen goes all blue
if it is a KP65ws500 it is one of a group of sets made by Sony where all the picture Tubes(set has a RED, Green, and Blue Tube.) ARE BAD. Most of these sets had all three tubes replaced during a program Sony had. The tubes are NO LONGER AVAILABLE---the only way to get one is remove the tube and send it out for rebuild---most of these cost about 250-300 just for the tube.
The set is shutting down because when the screen goes bright blue it detects one of the CRT's(tubes) is pulling way to much current.
The problem with Replacing your Blue Tube is cost and----sooner or later the other two(red and green) are going to fail also.
best advice is maybe not to fix it.
I replaced dozens of the tubes in these sets when Sony had a recall and provided the tubes for free and paid for the labor etc.
I know I am not giving you good news but I do this here for free and if this has been helpful give me a vote here. Thanks!

SOURCE: screen flashes blue, then shuts off
This model had a lot of problems with bad picture tubes--the blue one is the most common to go bad--the tube will pull so much current the set will go into shutdown.
The tubes are only available on a rebuild basis--very expensive and usually not worth doing.
THERE IS ONE OTHER THING YOU CAN TRY TO DO TO MAKE THE SET WORK FOR A WHILE.

Here is what you need to do.
1.) You need to remove the entire plastic piece below the front of the screen.
You most likely will find 3 screws on either side in back that you have to
remove.
2.) The grill will not come out easy, pull from one side and then when it
starts to come loose from the other side(there are several plastic pegs that
hold it in.) Then from the bottom pull out( most of these sets have square
plastic tabs at the top that tuck in.)
3.) With the grill removed locate the inspection plate behind it (it usually
has 6 screws.) You will have to tilt the grill to the left and on its side as
several cables are connected to it--they are held in place with trash bag like
ties that you can release to get some room.
4.) With the inspection plate removed you will see a fairly small (about 3 inch
square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with
whiteout so someone can tell if they have been adjusted.
5.) You need to look very close at the block with a flashlight----usually the
top three controls are FOCUS--don't touch those.
The lower three are usually marked Screen and if you look very close you will
see b, g, r(blue green red)
6.)Usually the blue will be on the bottom left--it does vary
7.) Once you locate the BLUE screen control have the set on and turn it
down--if the set is shutting down you may have only a few seconds to try to
turn it down---usually to the left with the Blue Screen control.
8.) Best way to do this if the set is on is on a video input
with nothing connected--you turn
the blue down until the set stays on and then very slowly turn it up until you
see a slightly blue screen with or without diagonal trace lines----if you get
it to turn on this way turn the blue screen back down slowly until the blue
screen and trace lines just disappear.
Let me know if you get it to work--Like I said if it is shutting down you may
have to slowly turn the blue screen down a few times to get it to stay on.
IF this works you may only be buying yourself some time--if it is the blue tube causing this sooner or later it will repeat--I have seen several sets where the adjustment allowed the set to work for another year or more.

Testimonial: "This fix did help temporarily, but had to take the blue completely out and it still flashes. I think it may be a lost cause and not worth fixing."
