Vertical Distortion fix for Toshiba 32 inch TV

You're talking about the pin cushion distortion; I presume. If this is the case, there is a separate circuit to adjust pin cushion distortion. Contact any service technician to rectify this problem. This is a skilled work. If you wish to get some details; check the site linked here. Pull up older posts.

This is a common vertical circuit failure and if you had distortion at the top before,that was the capacitors in the circuit failing which filtwer the voltage to the vertical ic which has now failed as well.A lucky fix maybe just resolderingm the ic pins! A reputable shop may able to repair for less than $100 or I can guide you further to fix your self if you have technical expertise.

Hi! the trouble you have mentioned indicates that your television's power supply is in trouble.

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!!

Yes if you could give me a model #, it is probably a diode shorted in pincushion area, or a capacitor.

refplace the regulator ic or transistor. chick zener diode. chick vertical capacitors

This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.

have a tech change your your vertical ic.there is also 1mf 50v cap that is located in the vertical circuit that usually goes bad have it change.good luck.

Look for vertical center control
