DM642 VGA/RGB and Monitor problem

Started by flash7gold May 20, 2009
HI !!!

I am working on project connected with video Processing.
Project was created in simulink and compiled by CCS 3.3.

Analog camera is connected to composite input of DM642, and to VGA/RGB output connected is computer monitor.

When I run a program everything was working well, but next day when i connected everything again i realized that nothing is displayed on the screen. I was searching for reason and i realized that when i connected different monitor, everything was working well again. But next day was the same story. Board stopped to work with second monitor too. Since that time i have checked many options, but i haven't found a reason.

I would like to add that LCD screen behaves like not connected to signal source. CRT screen ,sometimes after loaded program to board,change colour of diode to show , i don't know what, that there is kind of signal? I don't really know.

What could be a reason of that ?
how to solve that problem ?

Regards,

Flash
