Check the power setting of your PC.

• If you are on windows;
• Click on start button

• If you have vista or windows 7, type "poweroptions" into the search bar.

If not, open control panel and find the power options inthere

• In "power options" you can change when the displaygets turned off and when your PC will go to sleep, just change these settingsto the time you want, e.g. 2hours

I can offer support for other OS if required

You need an AC adapter 12vdc 5A regulated power supply.:

or shop around.

uninstall and reinstall the 914 file, it is corrupted

this monitor max resolution is 1280 x 1024, are you trying to go higher than this?
If not, then you kay have unstable DC in the power supply due to bad caps.

no data is getting to the monitor , check cable

I can't send it to your email address, but I can post it here for you.

Before you begin downloading the needed software, I implore you to disconnect the Microtek scanner from your computer. Unplug the USB cable FROM the computer.
[It isn't wise to leave a USB cable unplugged, and connected to a computer]

Also, if the scanner is turned on, turn it off. Unplug it from power.

Are you using Windows XP? (Either version. Home or Pro, doesn't matter)

If so, this is Microtek Support, and the download page for the ScanWizard 5; version 6.32 software, for your Microtek Scanmaker 3840,

http://support.microtek.com/downloads/drv_specific.phtml?cnntn=c&x=11&y=16&slct_os=8&step=2&prod=32&byctgy=1&drvgrp=489

Under the Description heading, (In the blue bar), you will see -
ScanWizard 5 version 6.32
To the right you will see - Main Installer, in blue.
Left-click on Main Installer

A small window will come up.
Opening drv_sw5_v6_32_ad.exe

Click on Save File

If you do not have your downloads set to save to your My Documents folder, (Start>My Documents),
this file will be saved to your desktop screen.
In either place, when you see the file, Double-click right on it.

The Installation Wizard will come up, and lead you through installing. (I advise just clicking on Next, Next, and Finish. The Installation Wizard will put the file in the appropriate place. You do not have to make any changes)

This software download has the needed drivers.

On the same page, (You may want to bookmark the page for future reference), you will also see a Help Guide listed.

It's the third file down that is listed.
ScanWizard 5 Online Help

Should you not be able to download these files, I suggest it is your anti-virus settings. Sometimes an anti-virus program, will recognize certain downloads as a virus, and not bonfide software.

After you have installed the ScanWizard 5 version 6.32 software, you may be asked to restart your computer. If not restart it.

After Windows is running again, and all your Start programs, plug the USB cable from the scanner into your computer. Now plug the scanner into power.
WAIT 1 minute, then turn the scanner on.

You should see a pop-up out of your task bar, at the bottom of your monitor screen. "Found New Hardware", and perhaps another one, "Found Microtek scanner"

Should you need any additional help with this, please come back, and post it in a comment.

The inverter is the most common item to fail on a LCd monitor. Capacitors usally fail the most. Are the tops of any of them popped up. If you had any shorted transistors the fuse would probably be blown. Usally labeled F1. I would replace all the capacitors first and go from there. Capacitors are cheap.

try to reinstall the OS..
TIA

Monitor clicks, pops, or makes other noises. Issue: Monitor clicks, pops, or makes other noises.
Cause: This issue could be caused by any of the below possibilities:

1. Monitor degaussing.
2. Monitor changing resolution.
3. Monitor syncing with the video card.
4. Monitor warming up.

Solution: Noise when turned on or off It is normal for standard computer CRT monitors to make a click, pop, crackle, hum, buzz, or other type of noises when they are first turned on or turned off.
Noise when monitor goes into standby mode When the monitor enters a "standby mode" or "power savings mode" this is similar to the monitor being turned off. It is completely normal for the monitor to make a noise when the monitor enters this mode.
Noise when opening Microsoft Windows or other operating system or when opening a game When a computer opens its operating system, for example, a computer opening Microsoft Windows or when a user runs a computer game it is very common that the monitor will need to switch its resolution of the operating system or game. When switching resolutions it is normal for the computer monitor to make some type of noise and/or for the computer monitor to flick or flash.
Noise during normal operation If the computer monitor click, pops, or flashes while it is being used this is not normal operation. It is very likely that the monitor may be failing or a component within the monitor has already failed and could also potentially be a fire hazard. We highly recommend that the monitor be repaired, replaced, and/or looked at by a qualified technician.
