This is a failure of the vertical circuit. It can be either poor connections at the vertical IC or a defective IC. If you can solder, you can fix this yourself. Please confirm that the model is C27A24T so I can get you the correct part number and costs.

Thanks,
Dan

Tv screen is black except for 1 horizontal line of color


The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

Toshiba 36A50 sound, light line horizonally on black screen


It is my guess that you have some intermitent solder connections in the Vertical output circuit.
Hope this helps,

No picture no sound


Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)?
If that is the case, maybe vertical IC failed or loose connection.

Flickering multi-colored line in the middle of the screen.


You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad

Black screen with colorful line going horizontally through the middle of the screen


Problem in the vertical circuitry.
If you have the know-how, check for "cold-solder" joints around vertical i.c.
Also, bad electrolytic caps.
Voltages ok?
Resistor values ok?
Replace I.C.

Don't tell me the yoke wires were off or gnawed thru by a roach!

Black screen, high pitched squeal


A set that has only a 1/2 inch bright line through the middle of the picture, from left to right, has a vertical output IC that is not working correctly. If the 1/2 inch line is in the middle but going up and down, then the horizontal yoke circuit has stopped working. These are problems which should be looked at by a qualified tech, but if the set was purchased 6 months ago then it should still be under the manufacturer's warranty.
