Sony KP 65WV700 Help

Not too long ago I had a problem with this tv where a repairman came out due to a misalignment of the blue color. When looking at teh screen there was a blue halo to the right of most images. Apparently it was some IT chip that got replaced. Now the same thing seems to be happening to the magenta color. Can you tell me what part and how to repair this? I can't afford the $400 to 500 or more repair cost. I am very capable with a soldering irn and can read a multimeter.

    My Sony KP 65WV700 Tv is having a convergence problem with the Magenta color. Is this a difficult repair and are the parts very expensive.



    Thanks, Rocco

This sounds like you are having a convergence problem and the convergence IC's most likely need to be replaced. Is the repairmans warranty exprired?

If you would like to repair this yourself please email me so i can assist you, also please include a picture of what you are seeing on the screen as well as a couple of the cirucit boards inside the tv so I can make it easy on both of us.

Thanks

Let me know are you handy with electronics stuff repair and can replace parts in circuit board to provide you more technical info OR local tv repairman will do this job for you.
Thanks.

hello High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

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.

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.
