Having problems with your Samsung 204T 20" LCD Monitor ?

I have a Samsung 204T display. It used to work on my powermac g4, but went blank years ago. I just now hooked to up to my macbook pro. The mac recognizes it and when I randomly press the buttons (keeping the power ON), it occasionally flashes dimly for a fraction of a second. I think it is showing the correct image, but then it immediately goes black again.


Answers :

The back light circuit has probably gotten bad solder contacts on the board since you get the image briefly. tap on the back panel to see if the image coincides with the tapping to confirm a bad contact
