Phillips Magnavox 27' Tube t.v.
Hi I have a phillips Magnavox 27" T.V. model# HD2717C101 Chassis # 27B800-7562 manufactured April of 98
After it was working fine it was shut off and when turned back on it has no picture, just a black screen with a single white horizontal line near the botton. The green power light flashes steady. Does anyone have any Ideas what might be wrong with it?
