TV: vertical colored lines on TOSHIBA TV Model 36ZP46P

The screen of my (conventional tube technology) TOSHIBA 36" TV, Model 36ZP46P frequently changes to brightly colored vertical lines, as if the tube's vertical amplifier suddenly & intermittently fails. The fault is intermittent in nature. It comes & goes regardless of whether it is showing a TV pic from its analogue built-in tuner or running a freeview pic from an external source.

The TV sometimes switches itself to standby and puts on a green clock-like indicator on the front panel. I presume this is a service indicator. Is the fault I've described very common - perhaps with a known solution?

No picture.Just a single line in middle of screen.


No, your picture tube is fine. This is a problem in the vertical circuit that deflects the beam up and down. This repair is fairly typical across most television brands and should not cost too much to fix. I don't want to quote another shops pricing but from us this would run about $150.00 to fix.

My 36 inch RCA tv has black bars on the top and bottom of the screen. The color is also dark even in daylight scenes. Can you help with this color.


as a general rule, vertical faults can be divided into two types: ones that cause geometric distortion (a circle will not be round) and those that simply black out a portion of the screen. the former are faults in the vertical oscillator, drive, or output stages. the latter are blanking faults. blanking faults are almost always caused by electrolytic capacitors changing value and thereby changing the timing of the pulses which blank the screen during vertical retrace. In other words, the pulses are turning off the video signals at the wrong time. the most common true vertical fault is geometric distortion and a foldover of white lines at the top of the screen. this is almost always caused by the electrolytic capacitor on or near the collector of the vertical output transistor or part of the IC which has the supply voltage (B+) on it. In the old tube days, the general rule was that bottom distortion was in the cathode of the output tube and distortion at the top was caused by a fault in the drive circuit. this may help the solution!!

Tv trouble


Sorry, I can't help you with the computer password issue but I can help you with the TV.

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace. You'll need to take your set to service center to have it serviced.

Good Luck!

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.
