Whtie line in middle of toshiba tv cx32h60


The vertical sweep output has failed. Check the vertical output section circuits for any loose solder terminals. Check all the solder terminals of the vertical output IC. Resolder all the suspected solder terminals by applying a little more solder. If these do not help you, replace the vertical output IC.

White line in middle of screen on a cx32h60 toshiba tv


The vertical sweep output is absent. Check its vertical output section circuit for the fault. Check all the solder terminals of that section, and resolder them by applying a little more solder. Take special care to the solder terminals of the vertical output IC. If these do not help you, check and replace the vertical output IC.

On power up I hold the power button down, I can hear some sort of relay kick-on, sometimes a horizontal white line appears across the screen, then it kicks-off, and the red led blinks four times...


Hi,
White line across the screen indicates that tv got vertical deflection failure problem that may be due to vertical output chip failure. If that kind of problem occurred, tv select protection mode and red light starts blinking 4 times.
Please check vertical output chip in tv main board and replace it to solve tv issue. This job needs soldering work so local tv repair shop will help you.
Thanks.

Television blank , but there is a white line across tube. I can hear audio


Your TV is in what is called "vertical collapse". About 70-80% of the time it is due simply to bad solder joints on the vertical output IC. You can verify this by tapping on the side or top of the TV, the picture may jump back into position. If it comes back it's as simple as re-soldering the vertical IC. If not, the vertical output IC may be shot or it may be missing one of it's supply voltages.
If the picture has been shrinking or had lines at the top that means there are some capacitors in the vertical circuit that were drying out. If it happened all of a sudden I'd bank on it being just bad solder.
Don't run it like that with that bright line for too long or it will burn in on the picture tube. Then if you do get it fixed you will see that line there all the time!

My 15 year old Toshiba Televisiononly shows a narrow horizontal band in the middle of the screen. Sound OK.


Hiii fairley,

You aren't specsificly dercribe yor tv set.
For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,etc..it's can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

Thank's

Toshiba 36AF43 36" just has white line in the center


vertical output IC has loose solder joints.if you continue to let it operate this way it will etch a burn line across the face of the tube so discontinue use.
