If the screen is totally black and only white horizontal line appear on the screen, check the vertical section if there is supply voltage on the vertical IC, and if there is none check the source of some open resistor connected to that IC. if there is supply voltage check all electrolytic capacitors connected in that vertical IC and it is better to replaced them all they are very cheap. and if it is still not working replace the vertical IC. post some comments if it is still not working and let see what we can do..

Have thin vertical black lines accross the screen


You have a defective optical engine. The symptom usually shows lines separated by about an inch vertically across the screen. It may be worth your time to call Samsung consumer relations and see if they will incur some of the cost.

Thin horizontal black lines


It looks like either failing convergence IC chips or a couple busted capacitors around them. This will need to be given for servicing.
You could try a hard reset first though: Unplug the TV from the power socket, remove all cabling, wait 5 minutes and replug to wall socket and redo cabling.

However, I think that you could have either convergence problems or a failing power board, for which you will need to get the set serviced.

Hope that helps!

I have a KF-42E200A Sony Bravia LCD tv. Recently we had to replace the lamp. Since then a horizontal line appeared at the top of the screen and it has grown to about 3 inches now. The picture itself is...


The lenses in the TV are more than likely misaligned due to heat from lamp. The heat can cause the lenses to move and the red shaded horizontal line appears over time because the lenses fall out of alignment.

You just need to have the lenses realigned and the red shading will go away.
