SOURCE: Vertical Lines all over then starts to move lines back and forth

you should first check all the cables inside the set to make sure they all are seated properly, check some other sources like a dvd player and see if it does it on a dvd, after that it is probably a defective main board

SOURCE: samsung 42" Plasma -Black vertical line when turned on.

It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.

SOURCE: green lines down length of screen on my samsung 40 inch LE40F8

The reason for the green lines are the resolution. I'm assuming you're TV is set at 1080i, not 720p or 1080p correct? What happens is the "i" stands for interlaced, meaning, your TV displays your images with scan-lines. The "p" stands for progressive, meaning, TV displays picture as a whole. You can not visibly see the scan lines when seeing 1080i, but certain TV programs are not outputting their show to the resolution you're at, which will cause you to have the green line up at the top of your TV. SOME TVs might let you adjust the settings to rid yourself of the scanline, but most consumer TVs will not let you without the maintenance code to protect your unit from over calibrating and braking your television. Hope this helps.

Thin vertical line runs across the top of screen on my Sony Bravia KDL-32L4000


Hi my name is Roety,
I can help you with your issue ,
 Try the format, aspect buttons on the Box remote, if the line is there on every input and effect the TV menu your panel (screen) is bad.
A new panel would cost as much as a new TV.

Sony bravia kdl-52w3000, turn tv on, no picture or


Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Sony Bravia - picture don't fit the screen


I have a Scientific Atlanta cable box w/ Time Warner. I followed the instructions below for the cable box. Somehow it reset my picture and I can now read the ticker at the bottom of the screen and the different picture sizes seem to work properly. Good Luck.
