(aobut 1/2 do not have LED back lamps this year)
also this monitor has CCFL back lamps that by now
all go: most are dead now, used every day 8 hours per day.
1: dim
2: yellow
3: dead
4: or works 1 day , minute or week then not. (random)


if the pc tests ok on newer monitor, then its not the PC
if the Monitors fails on other PC , turn off power saver inside.
if the CCFL is dead, shin a flashlight on the screen, see data.?
if yes, the CCFL lamps are DEAD. (now or soon or whenever)

It\'s NOT the fan. Check the power save settings on the computer ITSELF. Check your BIOS settings as well. Inspirons ALL do the same thing with waking up.

HP Pavilion Slimline S3400f Desktop.
dont worry ALL PC end up like this,, all do.. sooner or later..
NO OS stated, XP"? never post without OS stated, or answer get 10x more harder, See? make it easy for the helper and get more help.....
no Monitor stated. (maker, CRT, LCD what?)
The monitor is not fibbing to you BTW, the PC did go dead or to sleep. seems its monitor monitor of some kind with DVI.

if the monitor works on other PCs then the monitor is not bad.
i Bet it works (old ones 2002, have a hidden deep internal sleep mode. and is not yours IM sure now) DVI IS THE ONLY CLUE THERE.
So PC is dead. this PC came with only VISTA new,
is it still VISTA?????????
HP has support on it still
here (carbon dated by me 2008, IIRC)
https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-slimline-s3400-desktop-pc-series/3688715/model/3688723

this year,? get all those files and books there backed up
when HP support ends after 10 year rule, (be savvy?)


what keyboard USB or wireless keyboard mouse
use wired USB keyboards if wireless the battery is dead. easy no?

now in VISTA, go to Control panel, click power
turn off all sleep modes and all hibernate modes
the turn off screen savers, if turned on , disktop . RC right click
in display settings or personalize, turn off , need login to come out of sleep or screen saver.
try a real keyboard, that has USB cable yet? be first thing to do.
always keep a real keyboard, handy,,,
batteries fail. in all wireless devices like this (inside them)

luck you desktops have lies DIM fails. there are many.

http://www.pcdied.com/sleep-or-dim.html

one other way , and common is PC overheated.
all do that.
ever one not cleaned out every year,.

#1 all time cause of overheat and PC shuts down.

http://www.pcdied.com/overheated.html

No pc stated just monitor. (not even desktop or laptop) stated.
no OS stated, ether.
so ill answer in wide generic ways....
all computer are a problem, since days of Mr. Allen Turning to now.
ive done 43years of them just puters.(and other big systems MIL)
no person on earth can answer that common question
gee no pc stated,! nor can we lay blame until its fixed can we. ever.

3+billions of transistors. mine here typing now.
4,800,000,000, and friends, lots of other things to fail even LCD
its not a toaster or 4 banger calculator, at all.
its COMPLEX but 1 of those 2 boxs or cable are bad. sure.
(viewed in the MACRO)

sleep? how do you know it is sleep.
the screen showed that. text said SPEEP?
is the screen totally dead. (that is not sleep if true)
is the screens OSD button dead?,
the only clue i have here is one word, REGISTER (good word just too few)
so the screen never ever shows any text or HP logo ever
booting with monitor on for 5min. power on PC, see words?
no text ever...so.

then push the monitors.
Select menu buttons on front of monitors. and the OSD pops does it , it must....!!! see image below (mine is Viewsonic, near new)

there are many simple tests here.

• try you monitor on any other PC
• or try you pc on any other monitor

easy no.?, just 1 or 2 tests and bam, who's bad.
called the process of elimination..
but OSD is first. no matter what,.

if the screen tests ok,, (display tests and its buttons)
then the PC is problematic, (1/2 the battle won)
the first thing to do (tell me what pC) but turn off all sleep
modes in the CONTROL PANEL + POWER SETTINGS>
do that first. if you can even get the screen to work.

A pc never boots to sleep so.....
the PC can have 2 VGA jacks on the rear.
the PC can have DVI jacks, using those are you
try them all yet?
if you test the PC and it works and the screen works the cable is bad.


omg that screen is new, its even sold now at walmart.
not cheap either, too much, kinda
this is a modern 22" screen, LED>
and do not just go bad, is the power pack there and correct?
if the OSD screen is dead, check power first.

this is the Monitors brain, it works even with the PC dead.


the button is marked menu or select. this is test1.
on my monitor ,heck all 2004 up
it tells you SLeep mode when the PC goes to sleep mode
or shows Power saver mode. live on the screen.
screen power on first sure.

all ways to go black done here.

Three possible causes of sleep mode. first, an extensive screensaver with password lock prevents display. A condition that is observable as a blankscreen also known as sleep mode. Second, a computer power saver settings that shutsdown during idleness. Third, An improper shut down of the computer would have caused a sleep mode to save the system data files.



Restoring the computer to regular functionalioty

First solving predictable sleep mode settings
1. A movement of mouse pointer across the screen should reestablish unprotected password modes
a. password protected sleep mode would display an promp message requiring key code soon after the mouse pointer has changed direction

sloving unpredictable sleep mode settings
1.A computer power saver, screen saver, or splash screen displays prevnting programs acess would require manually powering off the computer system.
a. A manual power back on of the system should restore to program functionality mode

important notes
1. contact expert technical assistance

I've seen on a few Windows 7 machines has been the display turning off after only 15 minutes, even though I set the Turn off the Display option to Never. Weird!
You're probably reading this because you've tried changing the power plan settings to Never for everything and your monitor still turns off! This can be very frustrating and usually occurs with new installs of Windows 7, though I've seen it happen on older installs too.
In this article, I'll go through the different ways you can fix this problem. Note that if your computer is on, but the screen is showing No Signal or No Input, you should read my post on fixing blank or black screens. Now let's go through the possible solutions.
Power Options - Control Panel First, we need to make sure everything is set correctly in Power Options. Click on Start and type in power options or go to Control Panel (icon view) and then open Power Options from there.
Click on Start, then Control Panel and then Hardware and Sound, and then click on Power Options.

Click on the Change plan settings link that is next to the plan that is currently selected. In my case, the High Performance plan is selected, so I'll click on the link next to it.

First, make sure that Put the computer to sleep is set to Never. Next, change the Turn off the display setting to whatever value you want it 10,15 min etc.. You don't have to set it to Never if you don't want to. After this, click on the Change advanced power settings link.

Expand Hard disk and then expand Turn off hard disk after. Reduce the value till it gets to Never. Click OK and then click Save Changes on the Edit Plan Settings page.
Screen Saver - Control Panel The second setting you want to check is the screen saver. Go to Control Panel, click on Personalization, and then click on Screen Saver at the bottom right.

Make sure the setting is set to None. Sometimes if the screen saver is set to Blank and the wait time is 15 minutes, it'll look like your screen has turned off.

BIOS, Graphics Card, Monitor The two methods above are the most common reason why your display will turn off after a set amount of time, however, there can be other possible causes.
BIOS - On some computers, the BIOS can have power saving settings that determine how the computer sleeps. These are called sleep modes (S1, S2, S3, S4, and S5). On some computers, you'll see an option called Deep Sleep Control. You may need to disable this in order for the computer to wake up faster.
Graphics Card - If you have a high-end graphics card installed, make sure you have the latest driver and management software installed. If you go through the settings, you may find an option that puts your graphics card into lower power mode or something similar.

Monitor - Lastly, some monitors have power saving features themselves. Usually, the monitor is supposed to go into power saving mode if it doesn't detect any input (HDMI, VGA, DVI, etc), but sometimes it happens unexpectedly.

You'll have to press the buttons on the monitor to get access to the monitor settings. Those are about all the reasons I could think of for your display turning off when it shouldn't. If you have any other questions please post them here ,Best

trevor_jody, I hope you have valid HP warranty! If not , then you will need to do some reading at this blog: http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution/ The cheapest way to fix is DIY. But you and only you can determine if you are able to do the required work necessary to refurbish the unit. Swap-in a good unit to use while you are researching the common fixes for your 2338h unit. Your unit still works!!! Just not long enough! Your goal is to make it work for 20 million seconds. Try these other web sites also. www.ccl-la.com/badcaps.htm (site run by "buddymc") and www.badcaps.net , www.lcdparts.net Next thing to do will be to understand the "flashlight test" to determine state of your monitor's "switch-mode-power-supply". Is it in full or partial shutdown mode when screen goes BLACK or BLANK and BLACK? If you can still see Win-desktop after screen goes black, then SMPS is in partial shutdown mode. Blank n black=full shutdown. Do some reading in my and "buddymc" and "budmrtn" fixya profiles by typing our fixya "nicknames" into the "search for solutions or.... " bar at top of fixya screen and then hit enter or click search button. You will also find DIY video clips at YOUTUBE that will also be of some use too!! All that we ask you to do after doing your research is to come back to fixya and tell us if we were of some help and that you have learned something about how your monitor functions and if you have been able to make the decision to DIY or contract out the work needed to restore your unit to like-new condition. Bye for now. 12fixlouie
