Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

TV not working

Tv came on tonight when I turned on the power. Picture only covered 3/4 of the screen, from top to bottom. Sound was great. The tv turned itself off after a few minutes, the trouble light kept blinking "7" times. I downloaded the repair manual, so I will look the codes for you tomorrow, if that works for you. Bill

Picture is bending at the top and bottom and looks 3d

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

Sony kp-53HS10 blinks 5 times then picture goes off, sound ok.

Pull off the front speaker grill after removing 2 screws on the bottom corners. The grill will come out from the bottom before it can come down, then it is off. Undo the wires ties by hand to get 1 foot slack in the cables. Remove the 4 screws on the 1' by 2' hardboard cover to get into the bottom of the TV. Find the 6 adjustment pots (2 rows of 3 pots) One row is the "focus", do not touch these. The other row sais "screens". These you need to adjust. Turn on the tv. Use the tv/video button to switch to a black screen. You need to go up and down to get "cut off" to black for each gun/crt. Turn each screen controal clockwise untill you see color, then counterclockwise slowly and stop when that color goes black. Do this for all 3 screens = all 3 guns/crts =red, green, blue. If this Sony adjustment does not fix it, than you may need a new gun/crt which is expencive.

TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
