|
| My Hitachi 50EX16B will sometimes work for about an hour before the problem starts. The picture suddenly becomes washed out with red, green and blue lines running diagonally (about 25° or so) through it. Sometimes it will remain powered on but normally, after a few minutes the power shuts down. Not sure what the problem is and would appreciate any kind of help I can get. I'm an experienced tech but have never worked on a projection TV before so I'm a little timid. |
