NO PC stated, NO OS STATED, must we guess it all?
the last running CRT monitor on earth fail 17 years old.
how amazing, no:?
lost the manual you did, google finds is if you had tried.
the OSD menu, works. push mon. menu button
turn off the sleep timer
RTM always works why not do that.
read the manual
your MON is so old its before modern VESA spec sleep modes were invented,
so it had this silly feature called the sleep timer, with clock
yes has a clock too, crazy no?

page 6pdf.
tells me it does have vesa mode, sleep off the sync pins
on the same page this old relic,has DDC modes
but only work on moden PC< DDC uses a pin that was never used before on the VGA jack.
that same page also states, DDC2Bi (plug and play) only works on MONItgor jack B..
so note tell me your PC or its video card model if used.
or whaT this is (windows95.)>?'
we cant help much can we.
but you can test your monitor on another PC.
if that fails, the monitor is bad
but you must try both MON, rear VGA ports.
if the PC was dead, i sure can be.
youd have tried another barrowed monitor to prove that.
easy.
