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.

TV screen has a thin horizontal line in center

this will only help until the next time it is out of alignment but if you slap the side of your tv about where the line is it should straighten out but there is no telling how long it will stay straight......My sons tv was doing that and i had a tv when i was young that did it that is what my mom told me to do and what i told my son to do and it works.... the problem is an alignment or conection problem from dust most likely.

Tv screen is black except for 1 horizontal line of color

The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

A thin white line running horizontally in the middle of my screen. the rest is black.

The vertical sweep driver has failed. Get an estimate at a repair shop to see if it is economically feasible to repair.

Toshiba 36A50 sound, light line horizonally on black screen

It is my guess that you have some intermitent solder connections in the Vertical output circuit.
Hope this helps,

No picture no sound

Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)?
If that is the case, maybe vertical IC failed or loose connection.

Picture is black except for colorful horizontal line across tv

It sounds like you need a DEFRAG Done. Have you put any new speakers or magnets near the TV? Has anyone had a magnet toy or things around the TV lately?

Problem with tv

Could be a horizontal output fault, faulty power supply, a simple dry solder joint or HVT. If you can hear arcing or smell an ozone odour, it will be the HVT which may cost a bit.

Without knowing the actual cause, it's impossible to say how much it would cost to fix it.... could be anywhere from $50 to $250 etc

Best to have it checked by a technician and get a quote to repair... then decide if you think it's worth it.

Toshiba is generally a reliable brand, so if you were happy with the picture quality before the fault occurred, it's probably worth repairing.

Thin Horizontal line through tv blank screen.

Replaced vertical IC ( la78041 ??>.. Or La78040 ). Look for born resistor beside IC. Replaced capacitor 100uf 35V too!!! Good luck !!
