That is the OSD brain, inside said monitor
The On screen display , window.
push the menu key on said monitor, see that MENU now?
sure. that tells you the monitor is basically OK.
that message means the unstated PC, is not sending any video or sync signal (or its cable is bad or unplugged or loose)
or the funny timer is tripping.(out)
monitors evolved like 5 times from year 2000.
so first i carbon date yours, to see what you actually have.
FP7020 is not a TFT7020, got it.
i wish i could read the service tag on it so i can be accurate but i cant.
no matter both are now RETIRED. at HP (hp is compaq , a fact)
Zero support now... no books, no nutt'n!
the first monitors, had a timer inside, and a clock that had a auto sleep mode, inside it, yah. they did, and is a pain .
lacking the book , one cant know that can one.
seems its 2002 carbon dated. wow 15 years young , ouch
this is the year the VESA rules went in to effect.
long ago, and changed 4 more times. dig>?
found a 15 years old product sheet on this old display
shows"internal sleep timer" yup, I just knew it was there,....
first make sure its off. (this must be OFF)
if its on and the clock inside is set wrong, it will trip off , at odd times.
let me explain back in the dark ages of monitors.
they had many PC that had no sleep mode
so HP(old compaq) put a clock(time of day) and sleep timer in dislplay., (for US gov, energy STAR bs)
so what you do is first set the OSD clock to the correct time.
then in the same menu system turn off the magic clock.
magic is that only this old junk has this display
test the monitor on another pc to see if its monitor issues or not.
lets not say , the monitor , is ok, and its funny INANE sleep timer is shut off.
what next, well the PC is next.
but wait you never told what PC, ?
so it can be any of 10,000 different models , VGA cards, chips and OS.
endless possibles for 36 years of PC evolution.
hopeless on my end to speculate.
NOr did you say what OS you are running.+
All PCs shipped new have shipped with sleep turned on
or is this running OS2 or LINUX.
click control panel
there click power settings
there, click custom settings and give it a name, and then pick
NO sleep, no Hibernate at any time.
then turn off screen savers if on. most are off default.
when the PC wants to sleep it stops the Sync lines on the VGA card
or GPU chip.
the monitor sees that and goes to sleep. all do.
if the card is bad, its bad.
if OS is corrupted reload it.
if the PC runs ok on other monitors you cable is bad.
if the cable is ok the and PC is ok, then the monitor is bad
simply move the monitor to other PC
simple move pC to other monitor, and 1/2 the possibles are now know... in 15 min work, about.
