Absence of horizontal scan. Check and replace damaged component/s at its horizontal line output stage circuit. Check for any loose soldering at any of the components at this stage circuit. It is a common fault to Sony sets, that there happens some loose solder joints at this stage. Check for it too.

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.

Vertical lines down the center only means that you have a loose connection on the Yoke. Re solder all the connection on the yoke and where the yoke connection meets the main board.75481bd.jpge307a54.jpg

No Power on Sony TV

Be sure to use an ORIGINAL Sony transistor and be sure to resolder the pins of the small horizontal driver transformer and all parts connected to and around it, and your set should be fine.

Sony CRT Tv (KV-T29SZ8)

When you see white lines at the top of the screen, it means that the pump-up capacitor next to the vertical output IC is bad and the IC is about to quit. When the output finally quits, you get a black screen with possible dim spots. The vertical output IC and its pump-up cap will have to be replaced, and the little fuse resistors next to the flyback in the + and - supplies to the vertical output IC must be checked too. If you have experience working on TV's then you can do it yourself, but if not then have the set serviced by a tech experienced in Sony sets.
