Unit powers on, but SOURCE button cannot change screen from VGA

see if the is an AV button and press that
it changes"the signal in" source n ( pay channel,free to air antenna, x-box, dvd, etc)
the snowy screen indicates no signal and the icon is suggestingn it is looking for a input source

Press the Function Button to open the short cut menu. Locate the Input graphic and press the button for it. Each time you press the button, it will cycle between DVI and VGA input jacks. Allow a few seconds for the display to switch inputs. Make sure that cable is connected securely to the associated jack in the back of the monitor and the computer (or other source). If either VGA or DVI input is selected ,but the VGA and DVI cables are not connected, a floating dialog box indicates:

"No Cable Connect" or "No Signal"

If you have a DVD palying, Press the source button and see if the screen changes.

Hi My first guess is your signal board.


You can get parts at www.interliquidparts.com

I had the same issue as yours. After contacting the Acer support team, I got the response as follows. I tired and it worked.

"In order to resolve this issue, you may please perform a power reset. This will remove any static electricity stored in the hardware components that may cause the issue.

- Turn the monitor off and unplug the power cord and VGA cable from the monitor.

- Hold the power button on the unit down for 30 seconds.

- Release the power button and plug only the power cord back into the unit. "


Hope it helped.

Tramaine, I would suggest a new PSU. I have used ShopJimmy.com in the past with great success. Here is a link to the part you need on their site. Hope that helps! TeeVeeMan2
