Sony big screen tv

I have a red streak that goes across my televison. Sometimes if I turn it on and off a bunch of times it goes away for about 5 minutes them comes back. The television is only 5 years old. But I don't want to spend too much on getting it fixed. Any suggestions would be great help.

Re: sony big screen tv

Problem is with the voltage setting on the red gun... remove the front panel, there are four screws from the back, then you must tug pretty hard to make the panel come off, don't worry you wont break it, just tug hard. After you remove the front panel of the set and you will see a cardboard panel with a few screws, remove that. Now you should see the three guns... they should be labeled respectively. Now to fix the problem... You will see a phillips screwdriver pot on each of the guns... if you have a red line then turn very so carefully the red pot, blue the blue pot, green the green pot, you only need to make a slight adjustment and the lines will go away, when you first turn the pot you will need to break the factory glue seal, the seal is so that the set doesn't go out of whack during shipment. I had great success adjusting the pots, made my green lines go away instantly. One thing to keep in mind, when adjusting the pots you are changing the voltage to the guns, this works great only you might run into problems in the future with your guns blowing out, this happened in my case, fixed the lines for a few years but blew out the gun. To wrap things up... this set was poorly made with less than mediocre parts... almost everyone i know who has this set has the same problem... to fix this problem when the set is out of warranty will cost more than buying a new one... so... take your set apart and fix it and hope you don't run into problems in the future. Hope this helps... Jer

I have a KP-51ws520 that a friend gave up on and bought a new LCD TV. About a year ago, after a power outage in our neighborhood, this tv now has noticeable streaks across the screen at all times. Is...

It depends on what the problem actually is; are the streaks colors like red or blue outlines around lettering etc?

The more you tell me the better I can help. I will post a photo or two of what convergence problems look like.
This set is also prone to another problem, on a blank video input look at the screen: you should only see Video 1 (etc) and if you see faint curved lines (red, green or blue) and or the back ground is also wrong color you have the second problem.

let me know which it is.. If this information helped you rate this solution as very helpful as I do this here for free.

Hdtv has a red screen

Looks like you got some convergency issues there, I would consult a local repair place like put in your zip code and see if they service your area and TV.

They can also give you a estimate on how much it will cost to get it repaired.

Red and blue colors go across the screen. picture looks concave.

Greetings joanne7,

The issue you are having could be caused by your television needing the convergence adjusted. During production your televison has the three picture tubes that are converged to form a single image on the screen. Over time these can come out of adjustment.
If you go to this link and check pages 57 and 58, it gives you a very detailed guide on adjusting your convergence. I am aware this model number is slightly different than yours, but I own a 47" Mitsubishi and this is the exact procedure we use to do our convergence so I am confident it is fairly universal.

I hope this helps!

Go Ahead. Use Us.

Sony KP-51HW40

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.
