Re: Toshiba 32 SDTV
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.
Please let me know if I can be of further assistance to you.

this normaly means the tube inside the tv has blown there is no fix for this you could try unpluging it and pluging it back in well its on and see if theres nobes on the back to turn try turning them and see what happends otherwize it means your tube is blown
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..
Yes there is, a solution. There is a vertical sweep issue with your TV set. It could be a vertical output IC and or the sweep power supply feeding the IC. This repair will involve trouble shooting the vertical circuit, and replacing parts. If you have no solid state repair experience, my best advice would be to take the set into a repair shop and get an estimate on this TV. The repair, in most cases, should not exceed 125 bucks, and thats a high end cost. Good Luck
