Toshiba TV w/ horizontal Line... |
|
|
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
thanx for any help!

Ok It sounds like you dont know what you are doing.
Horizontal line is a Vertical deflection fault possibly bad
Vert IC ,Bad solder at the base or Bad Filter caps in that circuit.
Best call somebody in.

#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.
