No picture. Picture went from working, to blue screen, to black and unresponsive. Initially, power button illuminated green, but later, nothing. Any help would be appreciated. Tom

Flashes green yhen shuts off


Many of these sets had bad picture tubes--they use a red, green and blue crt. Most commonly the blue gives troubles--The tubes are now only available on a rebuild basis--usually not worth doing as the cost is very high.

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 leftto right will be marked screen------YOU need to locate the Green 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 green screen as well as the input number turn the Green SCREEN CONTROL SLOWLY TO THE LEFT UNTIL THE green is gone.

If this cures the problem you may only be buying yourself some time----if the 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 thetube would likely cost you 400 -500 parts and labor.

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

Screen fades from normal at start-up to blue in about 10 seconds, TV stays on, display goes black, sound still on, and red light on front blinks 5 times


These sets kp51ws500 had issues with bad picture tubes----this set uses a Red,Green and blue picture tube.

The tubes are only available on a rebuild basis and very expensive. There is one thing that requires no parts replaced you can try: here are the instructions:

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;} SONY WITH BLUE SCREEN PROBLEM:

Sony KP-53V35 - red tube issues

Red , Green And Blue.


Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.
