Hi,
The problem is your convergence circuit board gone bad. This is commonly caused by shorted/open IC on that board. First try to spot if there is a bad solder joints and resolder it. If nothing replaced the convergence IC. Also check the resistors around.
Hope it may help you.
Have a nice day!
Thanks for using Fixya.

David, you need to take off the front cover (where the speakers and power button are). On the back there are two screws on each side. unscrew those then pull. There are push in clips holding it on. 4, two on top two on bottom. Just pull hard, you won't break the cover, then find a place to set it aside (you may need to disconnect the front AV hook-up, thats simple, just unplug it like a outlet) and then there will be another panel, held in by four more screws take those out. Then you will find a like 3 inch square thing with 6 plastic screw knobs on it. It goes blue green red (could be different for yours, but should be the same, if not, one of the colors is labeled) Ok, no find the red one and turn it probably counter-clockwise. That will reduce the amount of voltage that the color red gets.
Oh, forgot to say, there are two rows of screw knobs, one says "focus" you can leave that one alone. the other says "screen" that is the one you want to change.
And also, when you are turning it. I'm tlaking like 1/8inch or less turn at a time. If not you can fry it and actually burn out the bulb. But I don't think it is burnt out. Just getting too much voltage

I recently bought a Sony KP-53HS30 rear video TV


Hello Sarah!
There is no bulb to replace in your TV. Image is created by three CRT's and you don't want to replace them, just trust me on that one. It could cost you up to $1800 to do that.
All you can do is to clean lenses of those CRT's. You have to disconnect TV from the power outlet and remove rear cover. Using very soft brush and vacuum cleaner remove dust from Red, Green and Blue CRT lenses. Do not use solutions unless you got something special for optics. Solutions will leave film on the surfaces. That would improve brightness and contrast of image.
To adjust focus front grille have to be removed. Than central piece cover held by 5 screws. Behind it you can locate black plastic "box" size little smaller than cigarette pack. there are 6 adjustment "screws". Three of them are "screen". You don't touch those. Another three "focus" there is one for each color. Turn TV on. Hit "menu" button. And adjust focus for each color separately. If menu goes away hit it again.
This is the only improvements you can do.
Everything else will involve humongous amounts of cash.
Good luck!
Russ.

Sony kp-61hs10 tv, has sound but picture goes black after 3 min.


I just had the same problem. If your lucky it might be a free 5 minute fix. The five light flashes mean impropper current. I took the front grill off, then behind that is another black cover, I took that off and noticed the circuit boards COVERED in dust. I then took an air can duster and blew off all the dust... works like new. No more flashes and in an out picture. The collection of dust was interfereing with the electrical current.

Sony kp-51hw40 I need to know were the red crt is.


If you take the front cover off and look at the bulbs, you will be able to tell which one is the red bulb. Looking at the front of the TV, the red shhould be on the left. If you need a red bulb, I have one that works fine.

Cleaning the screen cover on my sony big screen


Hi,
To clean its front screen, you should not open front cover as its complicated procedure. just take off its back cover as its shown in picture and use air-blower to clean dust. Then use soft cotton cloth to clean its screen from internal and 3 bulbs / lenses (CRTs) and job is done.
Need further help, let me know.
Bye.
