Question about Sony KP-53HS30 53" Rear Projection HDTV-Ready Television

1 Answer

Problems at start

My TV has worked great for 7 years. Now it whistles and different colored lines are scrambled on the screen and volumn doesn't work for about 1-2 minutes then picture clears up but the whistling stays for quite a while and comes back off and on. Sometimes you start it up and it's fine but we can tell it's getting worse. Picture is still great after its warmed up!!!
Thank you for your help.

COLOR PROBLEMS


Buying a new one certainly is an option. Sounds like one of the diodes on the circuit board went bad. If you want to pursue this I can walk you through it. Hit me back if you want to try this.

54inch Hitachi TV has double figures and colors red, yellow-not normal. Set approximately seven -eight years old. Lost remote control and direction book in moving. Is the set worth getting fixed? Generally...


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. This is called convergence.

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 Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, 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 set 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

60P8341 Rear Projection - Remote does not work


Your TV needs the part 313501707611 - it's the keyboard that's the cause of your problems - but here's the catch... Philips does not make that part anymore... they say that you need to either find someone to fix the keyboard (which I've had no luck on) or buy a new Television from them... hmm, a $2000.00 TV that needs a $20.00 part now becomes a plant holder in my living room because Philips wants us to purchase a new TV from them.

Tv reacts very slow


the problem is due to the crystal which sets the speed of the processor and it may be dry due to heat if that crystal is replaced or dry soldered the problem can be solved
