Question about Sony KP-57WS510 57" Rear Projection HDTV

1 Answer

The picture on my kp57wv600 has bands of green light that curves and appears to be in 3-D. I have some experience in technical repair. What part should I order and where in the tv is the circuit board that I should remove the defective part(s) and then install the new part(s)?

The problem you are experiencing is known as "convergence issue". It can be fixed by replacing the two STK convergence ICs. But before that did you try adjusting the convergence from the menu, by aligning the R,G,B crosshairs?

Removing green crt


More than likely you don't have to replace the CRT. Go to this blog for instructions for how to fix the most common problems.
http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

At the bottom of the page there are comments from users. There are several users that explain how to take off the front panel and where things are located. The model KP57WV600 is different than the pictures in the blog, including the fact that the order of the red, green, and blue adjusters are different.

If you try it and it's not successful and you still want to try to replace the CRT yourself, google KP57WV600 service manual and you can buy it for $9.99 and download it right away.

I wish you well.

Distorted picture on RCA LCD TV


I have the same tv. Had repair man come to my home in late april. Said it is the power convergence board. $225 for parts and labor I was told. Bad thing is part was supposed to arrive mid-may,then mid-june and now mid-july. He say's part is on back order. I'm actually going to contact RCA soon to find out if this is true. This seems to be a common problem with this particular T.V

If the screen control for the green picture tube is set too high, then the colors will be greenish, there will be green where there should be black and there will be fine curved lines (retrace lines) in the picture. If you feel confident then you can open the set and look for the focus block which has the 3 focus and 3 screen controls. One row is labeled Screen and the green control will be the center one. Try turning that control down a little and see is the green background and curved lines go away. If they do not go away then there is something more serious wrong. If you do not have experience working on projection sets then allow a qualified tech to handle it for you.
