Horinzontal white line with sound

Turn the TV off and unplug it from the wall and also unplug everything that is connected to your TV for about 1 minute and plug everything back in again. There could some thing wrong with the power supply or a problem with the t conn board here.

The controller board for the screen is going bad. check shopjimmy.com for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.

Nope, sounds like your tv is starting to give out. Recommend getting a new one.

This sounds like a loose solder joint, or overheated component. I know this may sound like a **** question, but have you tried tapping the TV to see if it goes away? If it does, you will need a tech to re solder the loose component. I have also seen this type of line and color bleed problem, believe it or not from poor cabling or loose connections.

bad electrolytic vertical circuit. need tech,

I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

Your tv has a video problem, leak capacitor in video section, near in flyback need to replace it.

replace the vertical IC problem solved

Too late now but I hope you had it serviced while it was still on parts warranty. With a couple of exceptions, service on those is by major pcb replacement.

Sounds like something is getting hot causing voltage loss or drive pulse loss to the vertical IC. Maybe you have a bad solder joint. Try tapping the circuit board around the vertical section. A capacitor could be heating and opening up. Stargazer Also you might try using circuit cooler spray and make the problem show up.
