Flat Screen TV Has Lines Going Through Screen - Possible ...

Sound like your Y-Sustain board has one foot in the grave. The Y upper buffer and Y lower buffer boards go when the Y Sus Goes too...

This is not fixable without professional tools. I would suggest you to get in touch with the place you buy it and see what they can do.

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.

hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

replace the focus block or try to adjust the screen control on the focus block for red only. this will affect the white balance of the set so adjust it carefully. the focus block is located on the front inside the set. remove the speaker cover then the 4 screws on the front plate. the focus block is 3" x 2" black box with 6 adjustment posts three for focus and three for screen. adjust only the affected screen (R).

if you have warrenty, return it. if not, then buya new one...the video fuses are dying...hard to fix it.

I really dont understand the problem Could we see a picture of this please?
