SG screen problem>??

[magpwr]

Ok,as some of you will know,i bought a new Atten SG(along with a scope and power supply) less than a year ago.Last time i used it(a couple of months ago),all was fine.Tonight i went to do some testing with pulsing an LED at high frequencies,and the pic bellow shows what i see on my screen now. So last time used-was all fine--two months later-it's RS.It is housed in a clean dry enviroment(the lab),along with all my other stuff.
So what has gone wrong here?.
Any help would be much appreciated.

hi tinman,

You may want to try your luck by touching the display at various corners to see if there is any improvement in display to discover if there is any possible loose connection to display panel.
That's the only solution i have from my end,can't promise anything.Good luck.

Perhaps the lab where you keep lcd don't have constant temperature that caused steam/dew/water inside lcd. so, check all connection, blow with "hot air blower" at necessary point carefully, maybe  will solve the problem.

Good luck, too.

Yes if it's not under warranty pull it apart and disconnect any and all connectors one by one and reseat them.   If it has any chips that are in sockets carefully pull them and reseat also (but I doubt there will be on this unit).   Use anti-static wrist strap or similar when doing any of the above.   Look for any blown caps or other obvious fried parts.   I fixed one 400 MHz digital scope that was only suffering a blown cap.   
I'd write the manufacturer also to see what suggestions they might have (if not under warranty).
