Try the following steps:

1. On the monitor, press Menu, and select Factory Reset.
2. If the monitor has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.
3. Connect the monitor to another computer. If the line appears when the monitor is connected to the second computer, the monitor might be damaged or defective.Otherwise, the video card and driver is causing the problem from the computer.let me know if this resolves ur issue.. if not then we need some other steps.. regards,guru

No Picture and no sound

Thats a generic problem with LCD screens. Its more common in Mobile screens. Sorry, no there is no fix to it other than replacing the LCD itself. Just pray that it shall not grow because as and when the compressed gas from within the LCD will leak the line will be becoming broader and broader. It is caused by damage to the LCD corner Just a hit on side of LCD and a hairline crack for giving way to the encapsulated gas.

I had to finally send the machine to ACER and it was a hardware problem; they have to change the cable linking the display with the MB

Hi...there,

Well... I hate to say, but you got a damaged panel. Thinking of replaced the panel... you can forget it.
Get a new one...it's will saved you the headached and $$$... Have a nice day!

Hi!!
I think that it's a hardware problem!!

just on a whim I'd say you have vertical output IC circuits in distress.

can you say Warrenty :->

You have whats called a verticle swep falure. Its probably just the verticle output IC but if you dont know much about soldering or circuit troubleshooting ,you should leave this to the pros. Theres way to much Hi voltage inside these sets to twiddle around inside them. Also there are no consumer serviceable parts inside these sets as well, as they are all solid state, and my advice is spend a few bucks and get a pro to do this job for ya, as it can, and will, kill ya if your not careful.. Is it worth saving a few bucks??? Naawww Call a pro.. Good Luck

My television has sound but no picture. I can not program the television because I can not see the screen menu. I also have tried to change the antennae but this does nothing to the picture's reception.

Do you have any ideas to correct this problem. There is no warranty.
