Check SMPS power supply DC voltages like +12, +5, +24 etc. If you are trouble shooter your self, you can try this with your multi meter.

But one doubt: When you say only horizontal line is visible there should be sound from the selected channels audible!!!!
If circuit is not available note down the IC numbers, track them in Google.
Note down the supply pin nos. You can check the voltages accordingly.

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.

This could be a capacitor if your lucky but can also be the horizontal transistor. The repair could cost you between 60$ and 150$
My opinion; it's not worth it.

TV BLACK SCREEN WITH THE POWER ON.


It needs repair.
If the line is vertical, then something is damaged on its horizontal circuit section on the mainboard.
If the line is horizontal, the vertical circuit section is damaged.
have it repaired to a qualified service center or person!
avoid switching it to avoid further damage on other parts!

Vertical line in center


If the line is "vertical" then the vertical circuit sounds OK. The problem would be in the horizontal deflection.

Check yoke connection and solder around horz defl circuit.

If the line is horizontal then I would suspect the vertical IC.

Toshiba TV CX2789K Horizontal Line


Failure in the vertical deflection amplifier section. This is usualy from failed components, and sometimes cold solder connections. Most of the time, I found bad capacitors, and sometimes the output IC or transistors (depending on the model type) that have failed.

Take the set to a service center for an estimate. You may find it more feasible to buy a new set depending on the parts that failed and the time involved to do the work.

If you indeed have a line down the center of the screen that means the horizontal output transistor is working as it produces high voltage as well. The rectifiers are working otherwise you would have no power or sound. What you need to look at is either the horizontal windings of the deflection yoke are open or you have a open return from the yoke to the horitontal output stage.
