----------------------------------------------------------------------------------
1- I connect the panel with the DVD player by (video in) and it work fine for more than 2 hours, without any problem.

2- then i connect my PC by (video in) and it work fine then after 1min the display moving down and down (sliding down) none stop!!!

3- i change the resolution to 640x480 60Hz, but its still sliding diplay!!!

4- !!!!! I return it back to the DVD player, and it is still sliding!!!

5- I thought its an input problem, then i connect the VGA in but its the same problem, sliding display down & down.....
-----------------------------------------------------------------------------------

* any body can help me with this problem, is there any adjesment built on the boards or some thing, and what is the phase option used to, i search all the forums in the WORLD but there is no answer!:confused:
