Picture has horizontal lines on screen

There are fine red green and blue lines running horizontally across the screen.The lines have a slight arc pointing to the top of the screen.
There is also one each, single red green blue line arc originating from the top and bottom center of the screen and extending toward the middle of the screen about two inches.These lines start and terminate about 10 inches from each corner.These single lines are more pronounced than the lines that run all the away across the screen.
The rest of the picture is clear and has good color.

Welcome to Fixya! It is failure of convergence ICs and these two ICs will be replaced on D board.
If you are comfortable with TV repair and know good soldering skills then can do the job easily.
Convergence ICs are mounted with sliver heat-sink on D Board of TV and part number will start with letter STK...

Horizontal blue lines with a slight blue wash in the screen


Hi,
Its because of Over Voltage of Screen (G2) to Blue CRT.
Take off front lower cover (speaker grill) and unscrew board. There you will need to find Focus Block mounted having 6 control knobs. 3 knobs are for Focus control and 3 are for Screen volts control. Find Blue Screen control knob and turn is Counter Click Wise slightly until bluish shade disappear on screen including few blue horizontal lines.
If you select AV input to adjust that will be fine as you do not need to wait for dark-scene.

Thin red horizontal lines across screen


replace the focus block or try to adjust the screen control on the focus block for red only. this will affect the white balance of the set so adjust it carefully. the focus block is located on the front inside the set. remove the speaker cover then the 4 screws on the front plate. the focus block is 3" x 2" black box with 6 adjustment posts three for focus and three for screen. adjust only the affected screen (R).

RED AND GREEN LINES HORIZONTALLY ACROSS TV


This sounds like you may have bad picture tubes. Most likely the green and red tubes. You would have to have them replaced and realigned. I would call a Sony ASC and get an estimate to verify this. An onsite service call could verify if this is what's causing your problem.

Convergence not lining up


Sounds like the green is out of focus. If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube. On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus. Hope this helps.
