Question about Toshiba 27A30 27" TV
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.
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.
