The monitor flashes on and off. Black then a half second of blue before gong back to black. Is the Monitor dead?

well, its a 2003 LDC 13 years old ,
its bad
the monitor itself of the power pack to it is bad.
you can test it on any PC< or laptop made
if its dead on all , then its dead.
what more needs saying,
older LCD monitors had old CCFL, lamps. that love to fail
newer are LED back lights that last for ever. it seems
so up grade?
seems your back light is dead
ever do the flash light trick
shine it at the dead screen see good data
yes, then the CCFL is DEAD< (or its power supply ,deep inside)
fixed may but would never do a 2003, not now.
lots of used good LED for sale,

see this trick, " omg the data is still there, and 30second labor to fetch a flashlight.
"omg the monolith is full of stars" 2001 space odyssey.
Omg the LCD is NOT DEAD AT ALL.
back ground laps,, KAPUT, all or half.

screen back light on the other side is busted which need replacement.

x2 test monitor on other pc.
if its ok we fix pC>
if the pc drops the sync lines H/V the monitor goes to sleep mode.
and tells you that.
the old monitors 2004 have timer inside,
does the OSD menu button on front of monitor work
with PC on,? it must.
OSD = on screed display from monitor brain
if yes, makes sure any menu there has the sleep timer off.
if it has it.
this monitor is old older than 2010. and has CCFL backlamps then and older.
so use flash light to see if data is on the screen if yes.
then the CCFL tubes are bad or the HV card inside dead.

yup your your service manaual
advanced OSD page clearly show the power saver clock
turn it off now.
of you cant get the OSD to work find a good PC
plug it in and turn this off below.


sevice manual google is your friend, sometimes.

replace c1853 and c1854 in power suply they are boath 1500uf

Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.

You may want to tey another computer or another cable or update your video card drivers. Otherwise look very closely and see if you are able to see a very faint image of your background picture or icons if you have any.

Really im not kidding it might be a backlight issue.

It could be a bad backlight bulb.

The green light only lets you know there is a valid video signal reaching the monitor. If the green light was not "on" your problems would possibly be within the pc itself. Something is not holding the circuit for the backlight "on" thus going black. Suggestions are: 1. Take it to get it repaired (if not under warranty) Hyundai carries a 3 yr warranty on this monitor.
