When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

is it turning off or going into sleep mode? If turning off, you have issues with the power supply. look at it and see if any capacitors are bubbled up on the ends and replace if you see this.

Open up the set and look for bad caps, see saome examples of failed monitors here: http://s807.photobucket.com/home/budm/allalbums

Go to your computer's Control Panel, Power properties, and change the power scheme to Always On, where hard disk shutdown, monitor turn off and system suspend are all set to "never". This should help.

try to disasemble ur video card then put it back again the open it...

mine just did this tonight. envision has a 3 year warranty and mine was within that so i am rma'ing it.

that happened to me. I felt stupid when I discovered what i did wrong. I attached the monitor cable to the connector at the top of the back of the computer(where it is supposed to attach, right?) - but, there was another connector for the monitor at the bottom of the computer which had been a special "card" add on. the monitor jack at the top did come with a plastic covering which meant not to use it. i thought the covering was just a protector, i didn't know. live and learn i guess.

Probably blown capacitors, the 19" widescreen uses 6 16V 1000uF
Do you have a soldering gun? Its not that hard to fix, get the capacitors on ebay for $6-$8 with shipping.

That mean your logic board of the LCD need repaired or replaced.
