Horizontal color line across the screen

I have a 25" Sony trinitron and all of a sudden I have a horizontal color line across the screen...have sound .This is on Video 1. What is so very strange when we use our DVD player it will show half a screen with sound. It all started last evening when I was putting the audio and video cable in the back of the tv. I have to tilt it forward to me a little to be able to place the cables in properly. I was doing this and all of a sudden the screen appeared with only a colored horizontal line.It will show a half screen with sound for all the regular tv channels.Has me baffled. Any help would be appreciated. Thanks, Bob Weaver

Most likely a bad Vertical IC or bad connections on the vertical IC. don't continue trying it on. If you have a bad connection it could do more damage. You also could damage the CRT ( picture tube ). If you remove the cover and look at the bottom side of the PC bord with a good magnifiing glass you may see what looks like rings around the leads comming from the Vertical IC. The Vertical IC is mounted on a heat sink usually towards the front of the set looking from back. If you do see the rings around the leads try reheating with a solder iron. If this dosen't fix you most likely need a new IC.

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.

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.

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.

Hi there!
Sounds like a power supply fault. You could try replacing all capacitors in the power supply and others areas around the line stage, with the same values. You may also want to check the tuner or "IF" circuit for dry joints. Hope this will help you. Kind Regards, JUS004
