I have a Syncmaster 971p and I can't find the autop adjustment button.

WELL step one is setting the PC, to a correct resolution the monitor allows. (I use avideo signal generator) so I not need to play PC games to do that. but can, forcing PC to 1024x768 is best NOW.
good news the screen is not dead. 2006 monitors most are CCFL dead. now. no text error and no OSD screens, do you get OSD button to work?\/
learn these rules. first (off CCLF lamps are not dead)
the monitor power button blue means ON, off black means powersaver mode (dumbb idea this color black, yellow best)
this old old monitor fails on vast kinds or modern resolutions
OSD page one try RESET?
learn that VGA + DVI scans can fail, on vast monitors. we simply go to the OSD menu and enable DVI, forced,source select Digital.
and now it all works well that is if no using the correct DVI port on the PC, mine has 2, one on video card and 1 on the mobo
the mobo port IS DEAD when VIDEO cards are present.
so that is one more way to get it wrong.
there is no w10/11 support on 2006 monitor that means w10 must be forced to a legit resolution manual per below. in desktop settings;
most monitors the OSD button is dead, after 10second just turned on. so power off, power on and hit OSD menu,button.
best is use PC with a modern monitor an force resolution to one of the below then plug in this lame 2006 monitor and see it work.

only these work at PC end to MON. note no 1080P !!!!! ouch!
VESA, 640 x 480
VESA, 800 x 600
VESA, 1024 x 768
VESA, 1152 x 864
VESA, 1280 x 960
VESA, 1280 x 1024

next time buy monitors 2010 or newer never older. oK?

free manual to read, on IT.

The button could be jammed, strip it and clean or replace the button

you have a loose connection either too your computer sometimes its a bad pin sometimes its a loose wire inside..

Good Luck

does it work fine on another computer?

this monitor series has bad buttons,I replaced my whole buttons panell and it is ok now.

The flicker might be caused by a defective plyback or a cold solder. Have it checked at the nearest service center.

Is the auto adjust button stuck?

I just had my Samsung 740N LCD monitor auto adjustment lock 2hours ago.

But i found this cool solution at www.fixya.com

"Press down the menu button(1st button on the left) for 5sec or until the menu display gone?"
and it works for me. Hope it will work on you

Thanks
