Question about Sony KP-57HW40 57" Rear Projection Television

1 Answer

Black screen w/small portion of top of picture showing at bottom of screen

I purchased a used Sony KP-53HS10, rear projection TV from a friend. It's about six years old and worked fine for three weeks, after I moved it the hour drive to my house. Suddenly we turned it on one day and the only viewable portion of the picture was the top-fifth of the picture, seen at the very bottom of the screen, with the red, blue and green lines surrounding the top of this "picture". The rest of the screen is black. One day the entire picture appeared for a few minutes and then the above situation returned again. Since then (a week) there has been no change. "Flash focus" does not help and the viewable portion of the picture does not include the on-screen menu, so I can't see what I'm doing with that and have resisted "flying blind", so far. Sound is fine and the problem exists when using DVDs and VCR, so it's not a signal problem. It is connected through a cable box.

The screen looks out of focus and the top and botton bend inward.

Remove front bottom panel behind it is a small black control box top controls are focus controls for R/G/B and Bottom 3 controls are your screen drives adjust one at a time turn off G/B adjust red first,then Do Green and Blue fter adjusting focu to each tube leave them set then adjust screen drive turn color off adjust RGB for a Black and white picture get as close as you can then turn color back If after doing this you still have blurry looking picture look down into Tubes you should be able to see picture clearly in each one if you cannot see picture then projection Fluid need to be changed out.

Removing the speaker grill from my Sony KP-53HS10

There are two screws (1/4 in. philips) located in the lower left and right front of the cabinet near the floor. They may be concealed by a plastic overlay. It can be popped off with a small screwdriver.

Be careful!

Sony KP-53HS10 rear proj TV - picture goes on & off

If the adjustment of the screen settings does not fix your problem, its likely that one or more of the CRTs (picture tubes) is defective.

And, the CRTs for these sets are hard to find and expensive.
