You have BenQ syndrome.
Sounds strange I know, but the power supply in your monitor is a BenQ manufactured part.
The problem is in the inverter section of the power/inverter board.
There are 4 small transistors (marked C5707) 1 or possibly 2 of these will have shorted out. Using a multimeter find the shorted one, and replace both of that pair, even if only one is shorted out.
There could also be other underlying issues as well that caused the transistor to fail in the first place.

I just replaced the ram on my pc but when I went to turn it back on it says no signal detected and goes. Black while the power light goes orange. I have checked and rechecked the physical connection over...


Your computer isn't starting up, no video is getting to the monitor, and that's why you see the "no signal" message and the power light goes orange. Make sure you've reconnected any internal cables you might have removed when you replaced the RAM. Also be sure you've seated the RAM properly into its socket. I've seen modules seated crooked so that contacts are shorted. The modules should fit properly into the sockets so the latches click into place.

Try reinstalling the original RAM and see if the computer starts properly. You might have a defective part which is keeping the board from starting up.

Since the trouble began after you replaced the RAM, that's where to start looking for the cause. Good luck, and thanks for using Fixya!

More likely to have problem in the power supply, back light inverter circuits, or worst will be bad lamps.

Try starting it after unplugging the devices Viz. Printer, Modem, ADSL, then during bootup Press F8 key to start it in Safe Mode..

Once you get in.. Run a checkdisk and diskcleanup.. and run Virus Scan etc. to get back in Normal mode.

Hi...there,
It's seems you got a defective DVI card. Try using a VGA cable instead. Have nice day!

When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.
