Question about Sony KP-51WS500 51" Rear Projection Television

Open Question

I have a sony kp51ws500, it turns blue after about 30sec with audio. What is the problem?

It used to take much longer before it turned blue but now it's down to seconds. The TV is still on because you can hear everything but the picture is completely blue.

SOURCE: sony 51inch tv blue screen appears

I had just adjusted the lower right adjustment on the screen focus block. 1. Remove the front speaker panel (there were 2 screws) 2. After the panel is remove, unscrew the sheet of plywood that's held together with 4 screws, this will expose the TV's innards (guns, etc) -- be careful. 3. At the bottom, there's a small box with 6 adjustable (via a philips head screwdriver) screws. Disregard the top row of 3 (they're for focus). 4. What I had to do was adjust the left most one ever so slightly with my philips screw driver. It seems the TV was over-firing blue causing everything to have a very slight blue tint as well as the lines. Once adjusted, the TV was good as new.

SOURCE: KP51ws500 turns green and shuts itslelf off

There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.

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 :)

I have a 2003 sony kp51ws500 television and there's a timer on the tv and it won't turn on. A red light blinks 6 times then nothing happens. I unplugged, I hit the reset button, nothing happen


read the instruction manual and see how to operate.
if the timer is for to sleep, the problem will be the IC associates with him, you must see the block diagram and w.diagram. and tracking the signal.
go to www. retrevo.com and download the diagram. God bless you

When i turn my tv on its an all blue screen i can hear the tv shows and everything but i caant see it then after about 1 or 2 min it completely turns off


This is one of a group of sets that had bad picture tubes; the set uses a red, green, and blue tube.

The tubes are no longer available from Sony.

There is something simple you can do: it requires removing entire front grill on front of set beneath the screen (two or three screws on back on either side.)

Behind it is an inspection plate and with that removed look for a black plastic block with 6 small adjustable shafts. Three are marked focus (do not touch those) and three are marked screen; they are marked but not easy to read---green is the middle in each row left to right.

You want to carefully locate the BLUE SCREEN control and with the set on turn it down until the blue screen just goes away, this is usually best done with the set on an unused video input, all you should see is video 1 etc, just adjust down until no blue is seen.

It has to be done with the set on and DONOT put your hands inside the set, I use a insulated screwdriver or plastic tool for this.

If this corrects the problem you may only be buying some more life from the set. I changed dozens of these when they were under warranty by Sony.

Before you rate this solution let me know if you have questions.

My t.v. turns on for 20 seconds then it just cuts the picture off but i can still hear the sound


The way to test whether or not the television needs to be repaired is to do some things to it after it has cut off the picture. Making sure you can still hear the sound but no longer see the picture turn the volume up and down. If you can hear the volume increasing and decreasing, but you cannot see the volume indicator itself on the screen then you'll know that possibly the inverter(s) is/are loose or that the inverter board needs to be replaced. If you can see the volume indicator moving back and forth across your television screen then you might have a problem with your signal source i.e. your set top box (cable box/satellite tv box), your connecting cables or the connections themselves.

Have sony kp51ws500 won't turn on, it clicks then shuts down and i get 7 blinks on front--had green, blue, and red line issues before


Hi wright
To answer your question;
The 7 blinks code(sony error codes) means that the horizontal deflection has stopped.
The common cause for this are transistors Q8035,Q8038 and the horizontal output Q8024 all located on "D" board.
Hope this help and let me know if you need further assistance.
