It is not clear whether one DVD or all DVDs play in black and white. If it is only one make sure that the format of the DVD is correct. If it is all DVDs, given that the VHS tape and cable play with color, there could be a problem with the chroma circuit in the unit. This is probably something that a technician would need to diagnose. Good luck.

Yes, definitely worth fixing. The problem lies in the vertical deflection voltage-doubler circuit. The usual fault is a single capacitor of 100uF/35V that has failed. It is normally connected to a rectifier diode right at the vertical IC. Replacing the capacitor (no more than USD4.00 in price) usually gets it working perfectly again. If you are finicky around technical work, then a reputable local repair shop in your locality should do it quickly for you and charge only labour.

SOURCE: White lines accross top of screen on our 27 inch Toshiba,

My Toshiba required replacement of two of the vertical filters/capacitors. Doesn't take long and the parts are inexpensive, but requires a repairman.

Horizontal white lines across top of screen. About two inches from the top, some channels more pronounced than others but always there.


Check for dry electrolitic capacitors near the vertical Ic output maybe one of 50v to 100mf or 50v to 10mf

Horizontal white lines 27A43.


You have some bad capacitors. They are located very near and next to your vertical IC. I would guess you would have to replace maybe four of these! Thanks for asking!

I have white horizontal lines about 2 inches at top of my tv


You have some bad grounds on the Vertical IC. In addition to this, in the immediate area of this Vertical IC, are a few bad capacitors. Look for this IC mounted on a large heatsink. It may have seven pins . I cannot remember for sure. I have not worked on this particular TV, so I cannot give you specific locations. But I assure the problem is in this area! If you have some electrical experience you can pull this board out. In this case only the caps need replaced and the IC resoldered. Good Luck and thank you for asking.

That problem is in the vertical section. Check for leaky or dry capacitor(s). Check the capacitor(s) with values less than 50uF.
Good Luck.
