The most common cause for this is a dry solder joint on the scan coil plug or under the flyback transformer. Sometimes the S correction capacitor, if used, goes intermittant.
I hope this helps.

TV TURNS ON,LINES ACROSS SCREEN THEN TURNS OFF BY ITSELF


sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

Vertical color lines on display screen


Hi!
If the lines appear while looking at the menu, then it's a broken LCD. If the lines appear only while taking pictures - faulty CCD. Contact your local Sony service center, but if they ask too much, you can contact me at toms.safranovs@gmail.com and I will give you a good price.
I work in Sony service center.

I have a KV27FS210 sony wega trinitron tv. It turns on and has a single horizontal line across the center of the screen then buzzes shows a continuous zigzag line from the top to bottom of the screen with...


The single horizontal line is a problem with the vertical circuit. Look for a small flat id attached to a heatsink that should be marked LA7837 or something similar. Try resoldering the pins of this IC first. If that does not resolve it, replace the IC.

Keep us posted.

Stuck in standby


The 4 blinks indicate a vertical deflection problem. Either the connections on the legs of the vertical IC are bad or the IC is defective. If you can solder, you can fix this yourself. Let me know if you wish to attempt the repair and I'll provide more details and instructions.

Line across top of screen


If the picture is ok otherwise then only thing that probably needs to be done is a vertical height adjustment. That is if the lines never changes position from cold to hot.
