White line I have a white horizontal line across my screen how do I remove please. The TV has recently been transported in a van

Unplug it,then wait 10 minutes,then plug it back in.

this is a frame fault
the fact that you can still see the line when the tv is off is because you have been watching with the line and it has burnt into the crt.

time to buy a new tv

If the 2 white lines are in the centre of the screen it sounds like you have a fault called 'field collapse' . The 'x' or horizontal circuit on the tv deflects the beam across the screen which in your case is ok because the line runs across the screen ok. The 'y' or field circuit on the tv deflects the beam down the screen. Without a circuit diagram for your tv i cannot point to individual components.

Hi,
I hope your TV model is Sony KV-G21M1 and you see color bars as horizontal lines across the screen.
Let me now are you tech guy or know how to repair TV to guide you further.

bad vertical chip ic

Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

sounds like bad capacitors on the FMT board need replacing that is a common fault with the first generation DLPs There are 3 bad capacitors.

I fixed the problem by taking it to a repair shop

Sounds like the flyback transformer is bad. couple of 100 dollars if it is that
