Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Sony KP 51 HW 40 Blue Lines


Some of these sets had problems with bad picture tubes; there is something you can do to try to correct this without replacing any parts.

v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} You may have a bad blue picture tube but there is a way to deal with this first----the set has a black plastic block with six controls---three are Focus(red,green,blue) the other 3 controls are Screen controls(red, green, blue) Someone has to remove the entire piece on the front of the set below the screen(usually a plastic part) most of the time it is secured with 3 screws on either side of the set in the back; once you remove the screws the entire piece should pull out(pull from right to left(it will not fall off or come out easy--it is held in with several large plastic pegs) With it removed there is an inspection plate with 4 screws-----the screen/focus block is behind it.

You need to look very closely at the block to identify the focus versus screen controls----one row left to right will be marked Focus and the other row left to right will be marked screen------YOU need to locate the Blue Screen control(they are black like the block) With the set on(be careful) go to a video input clip_image001.gif with nothing connected---if you see a blue screen as well as the input number turn the BLUE SCREEN CONTROL SLOWLY TO THE LEFT UNTIL THE BLUE is gone.

If this cures the problem you may only be buying yourself some time----if the blue picture tube is bad sooner or later this trouble may return----I have seen sets where this was adjusted and the set worked for a year or more with no repeat of the trouble----replacing the blue tube would likely cost you 400 - 500 parts and labor.

I do this here for free so if this has helped you rate this solution as I do this here for free.

Need help with my TV kp-51ws510. big screen the picture looks like someone squished the top and bottom of the screen. It dip down in the middle frow the top to the bottom.


The vertical scan amplifiers are loosing gain. This is usually caused by aging capacitors, and sometimes other types of components.

Because of the age of the set, it is possible that after servicing the fault the chance of having other component failures is high.

Kp-fs57 blue screen then turns off


Could be one of three things the yokes, the flyback transformer or the picture tubes, all will be a costly repair. If it was mine I would invest the money in a new one.

Open up the front of the set by removing the speaker screen and the black piece of particle board. on the bottom right you will see 4 knobs. Turn those knobs slowly till the arcs go away. The 3 knobs on the bottom are for color. the 3 on top are for the focus.
