Question about Sony KP-51HW40 51" Rear Projection Television

4 Answers

It looks like this procedure will solve my blue, wavey-line problem too, but the speaker grille for my KP-65WV700 is different from the one described here.  I'm not sure how to remove it. I was hoping that it would come off when I removed the six lower mounting screws in the back right and left edges, but no, it doesn't move. Anybody know how to remove it from there?

    The link you pointed me to (http://www.somelifeblog.com/2007/06/sony...) describes a different, but similar model from my KP-65WV700.  This procedure is likely to solve my problem, once I can remove the speaker grille.  The attachment of the speaker grill is different from the model described in that link, but it is an otherwise similar TV.


    Can you describe how to remove the speaker grill of my KP-65WV700?


    I've removed the six screws on the right and left-back edges, but it seems to still be attached somewhere.  From watching it flex as I lightly pulling on that piece of plastic, it appears to be attached about 6 inches in from the right and left edge at the top.

    By the way, I noticed somebody replying saying that this procedure did fix the problem for their KP-65WV700.  However, they didn't describe how they removed the grille.  It's definitely attached very differently from the KP-51HW40 shown in this link.

    Anybody else know how to remove the speaker grille from my Sony KP-65WV700? It doesn't have the covered screws described in the first steps ofhttp://www.somelifeblog.com/2007/06/sony... but it's otherwise a similar TV.

  • com88cet May 30, 2009

    It's not a problem with getting the screws to come out.  I have successfully removed the six screws that attach it from the back-right and back-left edges, but something else is holding it down.


    From pulling lightly on the partly loosened panel, what's holding it down appears to be on the top edge connecting to the screen panel above it, about 6 inches in from the right and left sides.  The lower edge of the plastic grille is free to move and the right and left 6 inches of it will move, but about 6 inches in, on the top, something is still holding it down.

    Could you describe the probable nature of this "lock system"?  What and/or where should I "press"?

  • com88cet May 31, 2009

    So then, assuming that I can ever get the speaker grille off, you anticipate that there will be greater shock hazards than described in http://www.somelifeblog.com/2007/06/sony...?

Hi,

So you got the six screws undone, great! Now you can pop off the front speaker grill. The easiest way is to work your hand along the top and bottom to pop the plastic out of the "holders"


After removing the screws, it barely moves at all. I can peel up the right and left sides a few millimeters, but that's about all. Obviously, I don't want to risk breaking it. So it doesn't feel like it's attached by wires in the same sense as what I saw in the pictures in http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html.
It's still quite firmly attached, and again, the attachment point appears to be about 6 inches in from the two sides toward the top. When I pull on the bottom right side, it moves out a bit, but when I pull on the top right side, it doesn't move very much, and past that 6-inch-in point, I can see it moving in a little, as if it were pivoting on that point.

I hope this would help you a lot.

Any further help, let me know.

Thanks for using "Fixya".

My sincere advice to you is please do not try to remove the cover by yourself. though our experts may give the exact way to remove it there is high of risk of electrical shock even though you open it in switched off condition, since the capacitors in the ic board are used to store the charge. it wouldn't cost you much for arranging a technician to just open up the cover and the grill you have specified. the fact that why i say your safety is more important than anything else. in television sets there are possibilities of developing thousands of volts and please give first preference to your safety. anyway thanks for contacting fixya!

Hi,

Not sure why are u getting stuck as it should also let the speaker grille to come out. Check the link bellow as it explains how to open up step by step:

http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

Even after a detailed discussion with the sony techs they are also of the same view:

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.

I am an electrical engineer by trade, but you do not need any technical background at all to do this adjustment. If you can operate a screwdriver, you can save yourself the hassle of a service call and save a few bucks. Make sure no kids are around when making the adjustment and make sure the screwdriver touches nothing else in the TV because the set has to be powered on to make the adjustment. Since the screen/focus block is right up front, danger of shock is extremely minute.

The adjustments have white marker paint on them, so if you adjust the wrong gun, it is a simple matter to return it to it's original adjustment by realigning the paint marks."

My tv 65rpwv600 just starts showing a blue colors on screen and after that it turns BLUE. i can't watch it but i can hesr it and also before this problems some very light lines (horizontals) were on the...


you either have a screen control drifting or a bad blue crt
you can access the screen controls behind the speaker grill and the black cover behind it the blue will be on one end or the other
there are 6 controls three are focus three are screen
turn the blue down slightly and see if it clears up before it shuts down the deflection if it continues to drift you might want to order a screen controls block and change it out

Remove Speaker Grille from Sony KP-65WV700


So you got the six screws undone, great! Now you can pop off the front speaker grill. The easiest way is to work your hand along the top and bottom to pop the plastic out of the "holders"

If what you are describing to me is the main wires still attached to the rest of the TV. So don't pull it out too far! If you do it right you won't have to unplug the wires, and save yourself some hassle... with this TV you'll have to pull it out JUST ENOUGH to get access to the carboard/masonite backing, removing such will give you full access to the six controls.

Adjust from there! Sorry for the wait, and I hope this helped out!

I have a KP-65WV700 and the screen looks a lil to green


OK, I'm the guy that was having the same problem, but had a blue tint to the screen. I also had blue lines running across the screen, and when I followed the steps below that were posted by another user not only did the lines disappear, but the blue haze vanished as well. My tv looks like it's new again, so you may want to try this:

I have fixed this several times on my KP 65WV700

As Slinteriors posted if it is a thin curved line you need to adjust the screen control, it's sorta like a brightness for each color, and if one color is too high it will produce a thin curved line.

The best way I have found to get to the controls is by removing the lower grey speaker cover front the front of the TV. There are 6 screws if i remember, 3 on each side. Then it snaps off, seems like its going to break but you have to pop it off pretty good.

Once its loose you have to remove a cardboard like cover plate in the center that will give you access to the small controller board.

Now be very careful while experimenting on which knob controls which colors. Turn them very slow, if you turn to fast you will cause your TV to shut down. If this happens, turn the adjustment back to original spot and turn TV back on and take it slow.

Adjust the correct color until the line just goes away. Its easiest to do this with a black screen.

Blue gun control


Remove the front speaker grille and also the smal;l access panel and you will see a small control box with 6 switches 3 control the focous and 3 control the screen control. The screen control will be laid out like the CRTs are Green in the center and blue and red on either side just turn the blue down very little or you will make the CRTs shut down.

Sony kp-65wv700


take the back off there should be a small rectangle with 6 buttons on it 3 for focus and 3 for the G2 (screens) some models have this control in the front behind the speaker grille behind an access panel and others have the control switch on the circuit board that is attav=ched to the crt neck. Either way its just a small switch much like a volume switch but smaller. Depending on what chassis you have it will be in one of the 3 areas I have mentioned. just turn it down a little. If that doesnt take the lines away you will need to trouble shoot the blue drive circuit.

I followed GuestUser/ Slinteriors advice and I fixed it. Open the front of the TV and there are 6 little nobs in the front. The botton 3 are what you need to adjust. from left to right the color controls are BLUE, RED GREEN. For the blue lines, slightly (I really mean very slightly) turn the botton left nob clockwise (right).

You have a bad blue picture tube. If you replace it the red and green will be weak and probably go sooner than you think. Everytime I had to replace a tube in a sony projo tv i had to replace all 3 picture tubes at the same time. It's very expensive if you don't have any type of warranty coverage.
