Question about Sony KP-57WS500 57" Rear Projection Television

1 Answer

The Guns? My tv is 6 years old. Three years ago when a tech came out to fix some white lines, he replaced the 3 picture guns (what he called them) free of charge due to an alert from Sony. Now, my tv has turned blue and may take up to 3 hours before I can see color and details. The tech was called and tells me the blue one is going out and it would be too expensive to repair! I've had cheap tvs last 15 years, this tv wasn't cheap and it only lasts 6 years? Help, please. Thanks, a frustrated senior.

    Yes! My repair guy said the tv would have to be shipped out to get a new blue crt and that there are no guarantees on the availability of one. I live way up in northern California on the coast. It's rural...not even a Walmart. Any idea who has them? Could I replace it?



    Thanks in advance!

My picture looks like it is in 3d there shadows on people


Older projection TVs use three separate "light guns" to essentially paint the picture on the screen. What likely happened, is one of your guns went slightly out of alignment.
You can either get it repaired, or attempt to align it yourself. It is doable, though tricky and rather risky. The process would depend on the type of TV you have. If it is a TV that uses the three separate light guns, then it's likely a few years old, and it might be tough to find instructions online for your particular model.

My has a double picture with a red ghostly picture in the background. Any information on how to fix the problem? I have changed the cables, viewed the different colors, tv input, and looked over the menu....


Hello,
It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergnce select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the curser (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It taked time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synch.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.Please run the convergence feature on your TV. Its giving you duble image because the red, green, and blue guns are disaligned. By running convergence it will realign the guns properly. You need to run the convergence feature at leat onece a week. Please note this is only for CRT rear projection tv's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to. Please refere to your tv's manual on how to do converegence and how to overlap the crosses because every CRT projection tv is different.
Good luck

Do not align the guns! they are located facing up toward the mirror; they are picture tubes! covered with big glass lenses! heavy!
instead look for a red/green/blue adjustment knob on the set's front; the buttons should say: convergence or, crosshatch push the crosshatch button: once you have three vertical lines crossing three horizontal lines; just merge them using the other R/G/B knobs untill you have one white vertical line and, one horizontal line crossing in the center of the screen.
(you may have to find the controls on the remote using "setup")

I have a sony 50 in rear projection. 9 years old


Sounds like the CRT tubes are going out which is fairly common on Sony. Inside the back of the TV there are 6 knobs - 2 for each color...one is for focus - dont touch - the other for brightness...turn down the brightness just a hair untill the lines go away.

Why does my TV have a red shadow on all the people and words. i've only had it 4 1/2 yrs


It sounds like the red gun is off. Your tv uses three guns(red,green and blue) to make the picture. sometimes one of these guns shifts a little and the colors get messed up and there are shadows because the gun is still trying to make the image, it just doesnt line up. This is a pretty inexpensive problem that can be fixed by most any tv technician for a small fee. If your pretty confident in your electronics know how, google adjusting guns and your tv and that should yield something.

57xbr2....tv turns on briefly...solid color screen for a second...then blank?


I had the same problem about a 8 months ago. I searched online and found that there is a problem with one of the color guns. They need to be replaced. I don't remember where I found the information, but there is a number or something to call for this problem. I think that my authorized sony repair man knew of the problem, there are other models that have the same problem. Anyway, sony replaced all three guns in my tv FREE of charge, and my tv was no longer under warranty. They did all repairs and fixed my tv.

sounds like bad CRT, some of these sonys have had defective CRT issues, usually all will come and go sooner or later (all 3 bad), you can pull the speaker grill off(either 2 1/4" screws on bottom or 6 1/4" on back sides) and pull off the Crt box cover (2'X3' piece) and lightly tap the CRT's with tv on, if they flare or get colored streaks in pix they are bad, CALL SONY 800 # and complain, also could adjust G2 (Screen control for color) for short patch. Will need new crts.
