Green squares pc screen

this means a ram or screen problem. Needs a serious repair as it will get worse.

go to bottom right of screen look for small green square when next screen appears there is a symbol that looks like a sun, slide your finger along bar next to symbol to ad-just brightness, this is how it is done on my 10.2

there is 3 small circular sockets on the back of your pc they are coloured pink, light green and green or black plug your speakers into the light green one if that doesnt work try the other sockets one of them should work and dont forget to turn on the speakers usually the power button is on one of them...or if you dont have speakers try plugging the cable with the light green on both ends one end into the back of pc and the other end into the back of screen you might have to locate it where you see the connection cable on back of screen it might be hidden up under that part of screen ...good luck hope this helps

Seems to me that the LCD cables are not properly atached.
Double check all the LCD connections.
Your problem will be solved.

hello there:
try by restarting the computer and using the f8 key you need to go to the last known good configuration it should restore if not you will need to reinstall the windows program hope this helps you out sincerely D.Jones

to make the green square show up just press the shutter button until half (this is called the half press) when the green square shows up then it means that the camera has focused already, if not repeat the process til green square comes out you can press the shutter button fully to take picture when you see the green square...

Hi Mary,

It's seems your panel it damaged, replacing it gonna cost you alots $$$... So just get a new one much cheaper...:) Have a nice day!

my screen is blank white

a 2004 relic tubby square
1024x768 reso only, it is not multi-sync at all. a real old dog
and the last one with the CCFL blacklamps on earth not dead, wow.
a treasure.
NO PC told at al
did not test this old dog on known good VGA PC that can do
1025x 768 and set that why first. (tricky blind for sure)
by blind I mean setting the PC up with monitor stuck on over-range is no picnic.
the great free service manual shows these words

Display "No connection Check Signal Cable" message. And go into standby mode after the message disappear

tests
does the monitor OSD screens work even with PC missing.
power on , under 15second , press menu, button
if menu is wreck(green?) the monitor is bad.
end story,
see page 3 step 3 hear and do the OSD reset..

shoe drops does green screen end if vga cable is fully disconnected from PC if yes then the GPU card is bad. in PC (unstated PC/card)
the GPU with dead R and B analog pins gives you green only screens.
that is it on 2004 mons.
