Question about Sony KP-51WS500 51" Rear Projection Television

3 Answers

Green Screen!!! I guess i'm not alone... My sony does the same thing. Turn it on, the screen turns green with lines across, gets brighter, brighter, brighter then shuts off. Does the stand-by light blink codes? If so mine blinks 8 times. Any help would be cool.

It could be the picture tube but it could also be the drive circuit foir the green tube, and I have fixed many a sony TV sets for this problem.. The best way to see if its the tube falure, is to take off the green crt socket and take off one of the tubes to the left or the right of the green as the green one is in the middle. If that turns green again and shuts down, then you know its the tube. If it does not turn green then you know that is in the green drive circuit. Most likly a bad driver transistor or the video jungle IC is bad. Oh and NEVER bang hit drop or slap your set to fix a problem. Thats the most stupid thing I have ever heard. The tube if its intermittant most of the time can be cleaned internally with a CRT rejuvenator. Who ever suggested driopping it is a fly by night repairer or unskilled or does not have the proper equipment to repair the set properly. you should know, anytime you have to hit or slap a set silly to make it work, most of the time there is a bad solder connection in sidfe on the printed circuit board and should be addressed or repaied asap as not to cause more damage to the set. Im still LOL about picking up the set and dropping it to fix it..LOLOLOL

I'm not a tech and I don't have a solution, but I have a repair manual. The 8 blinks indicates a High-voltage error, T8005 is faulty (D Board) Sorry, I don't know what a T8005 is, probably some IC. http://www.eserviceinfo.com/download.php?fileid=20644

I hate to tell you but the green picture tube is arking and that is why the set shutsdown,lift it off the ground and drop it about 3 inches only,sometimes it corrects the problem a long while,is worth the try.Dont over do it.Good luck.

Hi, I had a problem with my Sony CRT television.


The faint background lines are vertical flyback lines. Start your diagnosis by turning the brightness and contrast controls to minimum and view the screen in a darkened room. If you can now see a raster with horizontal lines visible then it is likely that the tubes A1 screen voltage is excessive. The screen voltage is usually within the range of 400v to 600v. Adjustment for this is often part of the flyback transformer. Check all high value resistors
in the screen and focus circuitry. Some of these reistors may be
built into the flyback transformer. As the picture gets brighter the beam current increases, this will eventually cause the X ray protection circuits to trigger shuting off the set. A fault in the video drive circuits to the cathodes of the tube will cause similar symptoms but usualy results in a predominance of one colour, ie
bright red, blue or green raster with flyback lines.

After turning on the screen it soon turns a green tint. I just transported the tv could I have knocked something out of alignment?


yes or the green tube is going bad. if it holds solid just a little green, you just need to turn down the screen control for the green drive. if it gets brighter and brighter green until its really intense, suspect bad tube or board.

the green drive knob is hidden in the front, behind the front access panel. its labeled but hard to see, only turn the one know counter clockwise, it will be labeled G and SCREEN, there are 6 knobs

Kp-65w500 green flash... led blinks 8 times


I am going to guess that model number is actually KP-65ws500

This is one of group of Sony sets that had bad picture tubes---red, green, blue----the tubes are no longer available and can only be obtained by removing the bad one and sending it out for rebuild (very expensive)

There is one easy thing you may be able to do to correct this problem---It involves no replacement of parts and is just adjusting the Green screen control---usually if this is the case when set comes on background will be somewhat (in your case) green---best way to see this is turn set on and have it on a unused video input---if screen appears somewhat green and has curved retrace lines--you may be able to turn the Green screen control down and continue to use the set---set will shut down if any of the 3 picture tubes pulls too much current--ie--goes to bright green, red or blue.

Let me know if you want to know how to attempt this

Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off

Hello im having problems with my sony wega


It sounds like you have a loss of green. This could be caused by the green gun in the picture tube opening up or the drive circuit for the green gun gone bad. Stargazer

Picture Quality


without seeing a picture I can guess that you may have a shorted green crt or the drive going to it has changed and you may need to turn down the g2 control for the green. If the tube is shorted or bad see what type of warrantee you have on the crts as some sets have two to 5 years. Good Luck
