Hp w2338h has no power

Possible that the main power supply has failed . It can be due to failure of the Switch mode driver in the SMPS unit.
please remove the panel and check only if you are equipped to probe and change the shorted components.

My fairly new HP W2338H monitor turns on but then goes black after one or two seconds. Do you have any advice for what the problem is or what the cost would be to fix the problem?

Fairly new? How new? If it's under warranty, you should have it replaced or fixed by HP or the store you bought it at.

You can attempt the following... unplug it... press and hold the power button for 30 seconds, repeat. Plug it back in and turn it on. This may reset it so it will stay on.

The cost of repair might be more than the cost of a replacement.

mcdevito75 here, Double check all connections at your monitor and computer. On the monitor press the AUTO button, this will re-set the factory settings. If this fails, I would bring the monitor to a Staples, Radio shack, Best Buy for testing, Monitor could be going bad even at a year old, also check any warrantees on the monitor.

I have a HP w2338h monitor that goes blank

It is most likely a bad power supply... I have had aboit 4 diff monitors do this to me... most common is under rated capacitors in the internal power supply... some times there could be a black light going out witch causes higher current draw on the power supply ( witch can take out the caps, fusses, transformers ( caps and transformers when they get week and bad can cause the buzzing sound ( on some times with a radio near buy then the monitor is acting up with blanking out and buzzine the radio will pop and buzz as well witch is a sign that there is arching going on IE. caps and transformer are most common for that )))

hope this info helps

When i press the power button to turn off monitor, i get a power button lockout message. how do i unlock the power button

I did not see anything regarding to the Power locked out function, may be it's time to call HP. Please post back what you find out from HP.
I look at HP WEBSITE:

Locking OSD settings
When the OSD is locked, settings cannot be changed in the OSD menu. The OSD functionality is enabled or disabled by pressing the Menu button and holding it for 10 seconds. Upon disabling the OSD, an OSD Lock-out message is displayed for 10 seconds. When the OSD is locked and an OSD menu button is pressed, the OSD Lock-out message is displayed for an additional 10 seconds. When the OSD is locked, pressing the OSD menu button for 10 seconds unlocks the OSD and displays the main menu. Identifying monitor conditions
Special messages display on the monitor screen for the following monitor conditions:
  • Input Signal Out of Range : Indicates the monitor does not support the input signal because the resolution and/or refresh rate are set higher than the monitor supports. Recommended refresh rates are as follows:
    • For the w1858 monitor: 1366 x 768 @ 60 Hz.
    • For the w2338h monitor: 1920 x 1080 @ 60 Hz.
  • Monitor Going to Sleep : Indicates the screen display is entering a sleep mode.
  • Check Video Cable : Indicates a video input cable is not properly connected to the computer or monitor.
  • OSD Lock-out : When the OSD is locked, the warning message OSD Lock displays for 10 seconds.
  • No Input Signal : Indicates the monitor is not receiving a video signal from the computer on the monitor video input connector. Check whether the computer or input signal source is off or in the power-save mode.
  • Auto Adjustment in Progress : Indicates the auto-adjustment function is active and in process.

HP 2338H Monitor Goes into Sleep mode and I have to power comput

you meant w2238w , right, you left off the w?
circa 2006 monitor, 11 years old.?

if the monitor fails on 2 PC, the monitor is bad ! ok, do that...
push the monitor menu buttton, connected to a running PC.
if the OSD is dead, , (on screen display , menu button front of monitor)
that means the monitor is dead, CCFL tubes are bad.
cold cathod florescient laml tubes all day this old.
the menu button can be in lock mode, hold the button for 10 seconds, and it unlocks
then go in the OSD screens if they work,. and turn off the sleep timer.
this timer is marked in the OSD as power saver,. turn it off.
it is a time clocked feature, and a pain to use on modern PC.
your PC does sleep modes today and never us this timer,inside monitor (default is on, turn it off)
all that is on page32 in your manual,
