    are you refering to the HV lead that goes from the slplitter into the CRT? If so you can repair that even if its sealed in the CRT CRTs are available used. Whats the model number of your set. But the HV lead shouldnt cause the symptoms your describing as a broken lead would cause electrical arching, not video distortion

    A broken lead should not cause those symptons. Whats the model number of your set? And broken HV leads are repairable.

    I wasnt aware that it was an LCD television. It would cost more to repair than to buy a new set.

Why does my tv have one blue, one red and one green line at the top of the screen but no picture?


The CRT inside the TV has gone bad. You can either find the make and model of the CRT and replace it, or get rid of the tv and buy another one.

Letters and numbers are 3d and curved picture


Hello

red, green, and blue lines curve across the top of tv is cause by defective convergence STK IC or you have open resistor at convergence section. if you have defective RGB Color vertical ramp probably you have defective STK IC..

I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...


According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

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

Red green and blue lines


Most projection TVs have an option to refocus. For example, my Sony rear projection TV has a button on the front for focusing the lamps. Try finding this button or option in the menus with your remote. Projection TVs actually use three lamps, one red, one green and one blue. These need to line up exactly in order to form a good picture, and when they come out of focus, you see the edges which sometimes has the effect of a 3D image when you aren't wearing 3D glasses. Hope this helps!
