Emerson EWF2004 has a horizontal line in the middle of screen some color can be seen the rest is black. I disconnected cable, unplugged tv line remains how can I fix it?


This sounds like an analog TV. If so, the vertical oscillator or vertical drive output needs to be fixed. You will need a schematic to do the job.

I HAVE A LC401EM2F EMERSON TV 2 YRS OLD. WHEN I TURN ON THE TV I INITIALLY GET GREEN VERTICAL LINES, AFTER IT HAS FOR BEEN ON FOR A FEW MINITUES, THE VERTICAL LINES DISAPPEAR BUT A HORIZONTAL LINE APPEARS...


It sounds like a power surge has damaged the color controller and scan line section of the circuit board. The cost to repair is more then the replacement cost. Next time use a UPS for protection (battery back up for computer and electronics). Regards DaytonComputerDoctor@hotmail.com

Vertical blue lines appeared on the screen with no sound.


Hello,

All plasma an LCD TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em. Good luck.

Picture junping


You possibly have a cracked solder joint in the vertical circuit, possible the vertical Ic itself. You'll have to remove the board and look carefully at the soldered connection of the vertical circuit and see if any are ring cracked. Some soldering should fix the problem. If you let the problem go too long the heat these cracks generate will eventaully short the vertical Ic..

Black Vertical line appeared on my Daewoo Plasma


Bad connection somewhere along the bottom or top of the panel, there are boards most likely along the bottom of the screen that control vertical drawing, a connection that breaks as it is heated up sounds about right. check the connectors along the bottom. Be very careful because if you wreck em the screen is junk. The connector that will be at fault will be in direct line with the black bar.

31'sanyo tv analog has a white horizonal line thru it


There is a failure in the vertical amp section. This can be the main output IC, or any of the support components in this area.

An experienced tech can troubleshoot the set, and determine and service the fault.

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace. You'll need to take your set to service center to have it serviced.

Good Luck!
