No power My Samsung SF-5100 has died after 5 years solid,albeit low use service. The power cable / socket is fine,but the machine seems dead (no LCD screen,nor any other activity.Is there any obvious solution or is it truly dead?

Samsung lcd monitor b2030
is the power LED actually dead?
is the screen 100% dead
is he front menu OSD button dead.
if yes, yes, yes, then the monitor is DEAD. of AC power is ok.

learn this fact all monitors before magic year 2010
are dead, due to CCFL back lamps burned out.

and will cost 2 times new, to fix it.
your manual shows year 2009
if it try to buy screen it shows me , the main board has 2 highvoltage CCFL lamp jacks.
so CCFL are dead. most are, most died in the year 2014
if run every day for 5 years, they GO DEAD.
or less if run 20 hrs /day.
if parked on shelf for 10 years, it works. see? 20,000 hours life spans.
best is to buy a 2011 and up monitor cheap even used.
with LED back lamps. and enjoy a long lived monitor.

CCFL jacks right side ! back lamps that love to die.

hold the red button in and swich unit on or put power in. it will reset but this models where the best but. if the rest do not help. it is time for a new one.

Take the power out. hold the red button in put power back.

you can try to take out the power hold the red button in and put the power back. if it still do not work. it is the mainboard. or liu

you need to replace the toner cartridge if you open the front an take the cartridge out give it a shake to see how much is left in ..

What is your question?

turn of the unit....
press the stop button hold it
turn up the power
wait till 3 sec.
then release the stop button
that should clear the machine.
