|
|
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. |

In first instance, check the supply voltage to the video output stages. |
