When I turn my TV on, white horizontal lines appear in the upper 1/3 portion of the TV screen. When they first appeared, when I turned the tv off and then back on the lines would eventually go away. Now the white horizontal lines seems to be permanent.

Re: toshiba colorstream 27A33 TV
1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect?
2.Or is thin Horizontal lines evenly spaced around an centimetre apart?
If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning.
If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.

It sounds like a power surge has damaged the color controller and scan line section of the circuit board. The cost to repair is more then the replacement cost. Next time use a UPS for protection (battery back up for computer and electronics). Regards [email protected]

1) Field collapse (horizontal white line on screen) R710 dry joints. Same as C2146TN & C2546TN problem solved with thanks to Mike G & Barty. Power off/unplug. Get to circuit board underside with aerial socket up-R710 is near top and right of centre-cluster of 4 joints best resoldered
