Question about Sony KP-65WS500 65" Rear Projection Television

1 Answer

My Sony KP-65WS500 is flashing blue screen and horozontal lines and now has a black box about 1ft x 1ft box in screen. It will do this for about five to 30 seconds and then cuts off. I can see the picture playing during this time but the picture is out of contrast. can anyone help. Is it worth fixing. It was top of the line when I bought it. Hate to loose it.

    Hello, I followed your directions. I had to turn down all knobs, Blue, Red, and Green before it would stop turning off. After it stop turning off I adjusted each one up until I saw the curved lines and slightly turned them down until they disappeared. It played continuously, but I still had the large black square (2ftx3ft) in the middle bottom half of the screen. The black square would go off once in a while then come back on. The black square would not appear on two or three channels. I think they were shopping channells or tv guide channel. I then pressed the guide button on the remote to watch two channels at once. This TV has picture in picture and also has scrolling channells if you want to preview them while you watch TV on the other picture. Thats when every went down again. It froze and all I saw was snow on both pictures. It would not change channels if I pressed the channel button on the TV or remote. It then finnally flashed red and turned off.
    I checked the capacitors like you said, but I could not see any of them that looked like they were popped up or poped out. Some of the capacitors had X and some had a K. I checked them all. What do you advise? Thanks

Hi,

Remove the front cover or the back. You need to look for the color gun it will look like a small box with 3 screws. Slightly turn the screws to adjust the color in your case in and out blue and arching lines.. Now the box sounds like a picture in picture function.. Would have to see it. Now it it cuts off power after 5-30 seconds after doing this you could have a bad capacitor on the power supply board which is sending the set into fault protection. A Bad cap with be poped at the top (X) -Top view of a cap should be flat. NOt rasied or poped.

Best Regards and Semper Fi

Can you confirm the actual model number of this set? Some had issues with the picture tubes being bad but depending on model number there may be a fairly easy way to adjust around this to correct the issue.

Thats a convergence failure issue. The Sony Type 1 convergence repair kit available from www.tvrepairworld.com is the kit your model uses. The kit contains the parts and the CD with instructions.

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

TV screen Flashes blue and then shuts off.


When it flashes blue, are the flashes bright blue lines going across the screen with the picture in the background, if so, It sounds like the Blue tube or blue driver circuit is breaking down after a short period of time. If this is the case, the uPC that controls the set is detecting a large current drain on and is shutting the set off for protection, An engineers expert eye is required I`m afraid. Ian.
