Electronic Projector display no signal?
Scenario:
I set up computer in our conference room. I plug the electronic projector
cable to the dedicated video card. I turn on the electronic projector first
and then the computer. After a few minutes, the electronic projector
did not display anything even the booting up of the computer. It only display
no signal. I check the cables and restart the computer again. But it only
display no signal. It sounds like there is a problem, its either the computer
or the electronic projector. This is the procedure I made.
1. I check the electronic projector if it search automatically the computer
that was connected to it. I press the search button on it then restart
again the computer. But nothing happen.
2. I think that there might be a problem in the computer. I suspected
that there is a problem in my dedicated video card. That's why
I open up the case of the computer and check the video card.
I notice that there is a blown capacitor on it. I removed the
video card and plug the vga cable into the built in vga adapter
of the motherboard. I turn on the computer and now it boots up
normally. The electronic projector is display the Windows operating
system.
Look at the picture below. This is the capacitor I have seen in my
video card.
