Looks like a problem with the vertical amp. Thats why you are getting a horizontal line. You may need to get it replaced. I recommend calling a qualified repairman to do the job.

Can I get rid of horizontal lines on my TOSHIBA model 27HL85 tv


VERTICAL RETRACE LINES is this problem called technically. Check all the solder terminals at the CRT base card of this TV, for any loose solder terminals.

There is a horizontal line in the mid


Hello

The vertical scan of your TV has failed. All picture tube type TVs have both horizontal and vertical scan sections to scan the picture on the secreen. When horizontal scan fails, you will see a vertical line at the middle of the screen, and if vertical scan fails, there will be a horizontal line through the middle of the screen. In your TV, the second stated has happened.
This may be due to an IC trouble or a voltage loss inside the printed circuit board of your TV. To rectify this fault you have to open your TV, and locate the vertical output section inside it. It is very easy to locate that section. There will be four wires goes from the deflection yoke; the coil fitted at the neck of the picture tube; out ot which, two will be thick and the other two will be thin. The thick wires are usually colour coded as red and blue. Colour coding may differ from set to set. Anyway you have to follow the tow thin wires, as they are carrying vertical scan signal to the yoke.
Following it, you will reach to a plug in point on the printed circuit board. Upside down the printed circuit board, and follow the track through which that wire connection goes, and finally you will reach to the vertical output section.
There may be transistors or IC used on that section. First check the voltage at the vertical output section. Voltage lose also may occur in this section. If it uses IC, check for any loose or bad solderings at the terminals of the IC. I advice you to resoder the suspected points by applying a little more solder, without shorting the terminals. In most cases this will solve the problem. If there is voltage, and there is no loose solderings and still the fault perists, replace the IC or transistors, whatever it may be, with same type and number.
If you want anymore asistance, fee free to contact me through Fixya. OK.

No image on a toshiba Cf27g50


If it is a vertical line, change the horizontal output transistor + capacitors. If it is a horizontal line, replace vertical output transistor + capacitors. Both cost around $10-20.

CRT TV picture keeps getting horizontal line & loud cracking nois


the horizontal section is near collapse, the lines indicate a sort or leak. Soon, the set will go black. Shut off as repair will be cheaper now! Needs professional repair as High voltage section is dangerous.. Unplug to be safe!

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;
