I have blue arched lines on my sony kp 57wv600 is there a fix for this
Those are retrace lines, the screen controls which are a technical control located under the front gray panel of your tv needs adjusted. This also could be an indication of a bigger problem, most common would be the focus block failing. it could also be of the picture tubes failing but this is not as common or possibly the crt driver ic's. There are specific diagnositc steps to preform to isolate the potental failure. this could lead to the tv going very bright then shutting down.
The first thing a tech is going to do is to adjust the screens and leave, somtimes this is enough, but sometimes it is not. if you want to try and adjust the screen i have an instruction set below, but i must warn you that there are high voltages present when attempting this adjustment and can be dangerous if you are un familure with tv repair.
Turn your color all the way down and the brightness in the middle, then
find the focus block, it will be a block with 6 controls one row will
say screen the other will say focus near the picture
tubes, adjust the screen controls(one control for each color) until the
picture has a good black and white look to it, then turn your color up
and it should look fine. This is how i balance out the picture. But
there is another method that allot of techs use, the other method is to
adjust the brightness up until you see what is called retrace lines it
is a jagged line going down the screen, once you see these lines back
the adjustment down just until they disappear. Do this for all three
colors. This method works but on an older set can throw the white
balance off because of tube wear.
