Toshiba CZ32T31, Vertical Deflection?

My television has a single horizontal line whenever I turn it on. It is a 32 in. color TV (cz32t31). I have done some research and keep ending up with a vertical deflection problem as my answer. Some sites go on to try and tell me how to fix it by mentioning parts that I've never heard of. Does anyone know where I can find free schematics or diagrams that I can use as reference? If anyone has any tips, please let me know. Thanks!

Usually the solder joints on the vertical output IC crack and the little pico-fuse opens. Resoldering the IC and replacing the pico fuse should bring the picture back. If you have never heard of these parts before and have no idea how to find them, then allow a qualified tech to handle it for you.

Vertical line

Check the deflection yoke connection cable for any loose contact at its connection socket at main board side. Unplug the connector out from the socket, and re-plug it back for at least tow times. Check the solder terminals of all connections to horizontal output. It will be best to re-solder all suspected solder terminals there. [horizontal sweep signals to the deflection yoke is absent now. Only vertical sweep is present now]

I have a thin line in my tv and i dont know what ic replace?

The fault is a failure of the deflection circuit and since you have not specified whether it is a vertical or an horizontal line the section failed will be related to the position of the line.
If horzontal the vertical IC or the section related is faulty and if Vertical the horizontal section., Now this can be the deflection IC, teh deflection coils or even discrete components like capacitors or resisitors in this section which will require a signal trace with a voltage test before the absence of the sync pulses are confirmed and the section identified.
I request not to change the IC unless it is proved but you can solder the vertical IC or the section concerned -- if there is dry soldering.

When I turn on the TV with the remote or on the front, it comes on for a second and then shuts off. I was able to keep it on once, and all I got was a horizontal white and colored line across the TV, but...

horizontal lines indicates that the vertical section is most likely the defect..a defective deflection yoke could cause this and eventually damage the vertical output ic causing an overloading in the power supply then can caused to shut down

Want to connect computer to tv

You can't connect computer diretly to your Toshiba TV. You must have a VGA to AV converter in between TV and Computer. This device is available in most of the electronic spare part shops. OK.

I have a Toshiba CF32H40 TV that is displaying a Single Horizontal Line. Any help would be great

you lost vertical deflection. this will require parts replacement, however it is possible it is only bad connections (cold solder joints)

My CRT TV displays a single horizontal white line across the screen. It will flicker and try to display the picture. If you smack it you'll get a quick picture then back to a line. After about 10-15...

The single line means that the vertical deflection doesn't work. And since it is working when you kick the tv or has warmed it's clearly a bad connection - open the case and reseat the wires going to the tube coil.

H line problem

I think you are describing 'no vertical deflection.' If all you have on the screen is a single horizontal line, the vertical deflection circuit (or IC) has died. Unless you have service documentation on hand, I can't give a part number to replace but this is typically not an expensive failure and if the set was OK before, it is worth having repaired.

Toshiba 32A14 horizontal line

This symptom is characterized by a thin horizontal line in the middle of the screen. This symptom is caused by the absence of the deflection sawtooth current in the horizontal deflection coil.
The trouble is easily isolated by a continuity test and by checking the most likely defective components such as A)open vertical linearity compensation transformer, B) open capacitor and C) open horizontal deflection coil.
Be sure to decrease the brightness first before trouble-shooting if the line is very bright,as it burn the phosphor screen..

Hope this may help;
