#1 issue, if the tv has been run with that failure for long, the
picture tubes have been damaged and the phosphor probably has the line
burnt into them.
#2 Time to stop using the tv and call a trained and experienced
technician to give you and estimate for the repair of the set.

p.s. No, this problem is in no way related to a bad horizontal output
transistor. Time to have someone who knows tv repair have a go at it.

Hello,

I have a Toshiba projection TV which has a horizontal line going
across the
screen when I first turn the TV on. The Line is maybe 1/4-1/2" in
size. After
about 15 minutes the line starts raising up and eventually goes to
the top of
the screen and disappears.

Could this be caused by a bad horizontal output transistor?

I tried replacing all the caps since from my research I see that is
the main
problem.

Oh yeah its a model no. TP4871B
