im afraid to say your display has gone contact funai they should be able to help you replace the display.

you didn't mention the model and make :)

Philips 50 inch plasma tv no video but has sound

Aside from the parts you mentioned check the vertical connection to the yoke (usually yellow and green wires), it may have a cracked solder joint or it could be burned. Also check the yoke for a broken vertical winding.
If the line is yellow with no other colors you may also have a bad color gun or drive transistor. If all color guns are working the line should be white.

Here is a picture of my TV problem, the green horizontal line is from the camera flash. thanks for the help.

It's definitely possible. I'd have it checked by a repair center for something like this.

take your tv to a tech the tv is having problem in the color circuit and the vertical circuit.
