Question about Sony KP-51WS510 51" Rear Projection HDTV-Ready Television

1 Answer

Screen is too blue

When it's first turned on the screen is okay. Then after a while, it goes bluish. For a year or two, I saw the blue retrace lines. Now it's too blue. Anyone know how to adjust the color guns? It's like I just need to turn the blue level down.

You will have to take the front cover off, usually 3-6 screws holding from the back, when it does come off there will be wires to the control panel attached still. you will also have another panel to undo. after that there will be a block with 3 focus controls and 3 screen controls marked b g and r for the three colors. The blue screen control is the one you are looking for, be very careful the slightesr turn has huge response including shuting the tv off when you turn it the wrong direction to far

I have a Mitsi WS-65807 65" Played Wii for about two hours. Lost sound then picture. Now it wont turn on. Just get a warped bluish screen with lines. Any Suggestions?


Well i need more info. have you tried unplugging the tv for around 60 seconds? Was the "warped bluish screen" right before it died. Or is this when you turn it on it happens?(Bluish screen)? Because if no power at all and no picture at all. Could be Power supply. If you have some sort of picture with blue lines that are stable? You have a convergence problem. Get back to me with info i can help.

Z3 projector.3 years old. Blue tinge in one corner of projected picture. Grainy picture on dark scenes.


There may be some problem with your picture tube else try this that looks like retrace lines. Anyway, you should try to adjust screen pot not focus pot. Make sure you are turning blue screen pot (there are 3 focus pots and 3 screen pots) and do it slowly. If you turn it too much, it will affect your grayscale

Too much yellow does not adjust with normal drop screen adjustments. can i adjust the light beams.on my philips 50"


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;} 1. Turn the green screen control on the Focus Block until retrace lines appear and gradually turn it back
Until the point where you can see the retrace line disappears, just before cutoff.
2. Turn the red screen control on the Focus Block until retrace lines appear and gradually turn it back
Until the point where you can see the retrace line disappears, just before cutoff.
3. Turn the blue screen control on the Focus Block until retrace lines appear and gradually turn it back
until the point where you can see the retrace line disappears, just before cutoff.
4. If the screen still appears too bright after proper G-2 adjustment, you need to adjust the sub-bright adjustment in the service menu
control down until screen cut-off. (Service data Range is usually 21 to 25 in the Service menu, for Sony sets you first go to category "MCP2", & then adjustment item 01( "SBRT")= subright.
For electrical the focus, put on the screen a clear picture of your choice thru an input of the TV set from a DVD, then pause the playback of the DVD Look into each color and rock that color focus control back and forth (turn the control one way then the other way slowing down as the picture goes into the best focus. till the picture looks sharp do each color till they all look in focus. NOTE: it is best to look into each color tube to achieve the best electrical focus. For optical focus please follow the manual lens adjustment in the sets service manual

Lines on the screen


Are they thin, white lines running east to west? If so, they are called retrace lines and indicate that the screen settings for the picture tubes is set too high or there may be a mal-function of the CRT driver circuitry. Try adjusting the screen controls which are located behind the front grill of the TV behind an access panel. Once you remove the grill and access panel, you'll see a small control assembly the has two sets of controls. Three for adjusting the red, green, and blue focus, the other, the red, blue, and green screen controls. To adjust correctly, put the TV on an unused input(dark, blank picture) and adjust until there are no visable retrace lines or color in the image.

Sony 65 inch screen tv


The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.

Blue and red arched lines on screen when background dark


Sounds like you are describing retrace lines that could indicate that your CRTs or something in the drive circuits are bad.. Check the resistors on the CRT sockets to see if they are in tolerance. If they are try turning the red and blue screen adjustments down just a little this should take the lines away. You will however be needing service in the not to far future. Turning the screens down should help if the resistors check out. Let me know if you need anything further.

BLUE SCREEN


I got this Sony KP-57WS500 57 in TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE. http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

Sony KP-51HW40


I had the same problem with mine 2 years ago (TV was 1.5 years old at that time) I had extended warranty on TV and it was fixed by Sony at no cost to me. Now yesterday I have another problem with it. All of a sudden screen went BLUE. No Sound either. It could be the CRT (That's what I read here) Out of luck this time. Will call local Repair shop (70 miles away) and see how much it will cost to fix it. Good luck.

replace the pcb convergence board,, It costs $96 and takes 10 minutes to replace you will have to manually line up your convergence afterward as the settings go to factory default. Everyone that owns this set has or will have to replace this part within 3 years
