Sony FD Trinitron WEGA KV27FS100 horizontal lines across top part of screen


Check and replace all electrolytic capacitors in the vertical output section circuit. There will be 5 or 6 of them to replace. Replace all at one time. The fault you describes here is technically known as 'vertical retrace lines'. Visit the site named 'Electro-help' for more details. Click this link. View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. There are more than 990 posts to different brand TVs now. Sometimes, you might get some more details from there.

Pink/Blue horizontal line on TV


Considering it is a 32 inch set and costs now under 300 dollars it may or may not be worth fixing.

To give an educated guess: either whatever it uses for an inverter board may be bad or damaged OR even the main board that processes all signal into or out to the screen may have either a bad connection(unlikely but possible) or be causing this.

A fatal issue could be something wrong in the screen unit (panel) itself.

I gather set is not under any warranty at this time.

My flat screen tv has different colored horizontal hold lines across my screen. Where is the button for horizontal hold?


Those colored lines are a bad panel. Is no button to make them go away. The only fix is to replace your panel. Would be more cost effective to replace the TV.

I have a horizontal color line across the screen...have sound .This is on Video 1


If you are comfortable working inside the set and can solder, try resoldering both the vertical IC and the input jack connections. The vertical IC will be a small flat IC attached to a heatsink with about 9-11 pins. It will be marked LA7837 or something similar.

Let me know the results.

Single green line spanning across the screen horizontally


I was just watching TV and all of a sudden the screen minimized down to a single green line spanning across the screen horizontally. The label in the back says it was made in 1996 so it is an old tv. Can anyone help?

Horizontal (dashed) line across screen


On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck
