Question about Hitachi Computer Monitors

How do you reset HITACHI Monitor Model: CM751ET?

Hi their I am having a problem with my Hitachi monitor (model number listed above), I can’t seem to reset the monitor for some reason their is no reset switch located any ware around the monitor and I’m unable to correct the problem through computer display settings either. Their are all the standard controls apart from reset.

The screen seems to tilt in toward one direction and I’m able to see sloped dark patches in the bottom right corner, almost like a small tilt where the picture disappears. I have attempted to set in right by fiddling with the controls at the front but no luck stays the same. I have also tried to find the user manual but have had no luck.

Can you help me sort this problem out?

Hi HarryH, Sounds like the web cam software may have changed a .dll or some other system file that the video chip is using. I would try uninstalling any software from the cam and removing and reinstalling the video drivers. Have your windows CD or the CD that came with the PC handy we might need it. Open Device Manager Control Panel > System > (or hit Windows key + Break key) and if you're using XP switch to the Hardware tab and click Device Manager. Double click Display Adapters. Right click the video adapter listed and click Uninstall. Click yes you're sure to whatever warning message comes up. Now reboot your PC. Windows should auto-detect the video and re-install the correct drivers. There IS a possibility that the first re-install could use the same bad if while re-installing you DON'T get asked for the windows CD and you still have the problem after rebooting, go to the manufacturers web site and download the drivers for your system and force windows to install those files. If you don't know how and it comes down to needing to try that let me know I'll walk you through. Please come back here and comment this post, some people have been missing the "Add a comment" link at the bottom of the post. Starting a new thread to answer an Experts questions makes it hard on the prople trying to help. :) Let me know how it goes, Dude

Dear Carol,

You can check at rear of the the monitor.
Sometime they assmbled the switch at the back of the Monitor.
May be that the switch is located there.

SOURCE: Screen not coming on

Typical problems with Samsung SyncMaster.

I just did this to a friends monitor as well, a different model and not much different in build. I think you might have 3 screws on lower back side of cover. Start your separation from the bottom of the frame.Your power switch will remain on the front frame while the wire will remain with the rest. Read the rest it will help.


NO SCREWS!!! Assuming that the stand mount has been pulled out..The seam around the screen frame is where you start(different versions might have screws). The frame has the prongs, the back cover has what the prongs slip over.The frame is coming off first! I got the side to open by finger, then used a small standard screwdriver to pry ever so gently(lifting frame from rearcover). Leave the power button assembly on the frame, pull wire only a little to relax any get about 3/4" in extra taped to panel. The hard part is done.;) Still holding the frame...Now lift the panel (where the power button assembly wiring goes under panel) with the power housing that is under it as a whole and you will see where the powerbuttonassemble detaches.Remove frame. Now..holding edges of panel into back cover, lift and flip the whole thing over and place panel face down on a perfectly flat surface..a towel on my desk works. Lift and remove back cover.Your now looking at the back of the board housing. The ribon is simple, on the panel end of the ribon, squeez the outer clips together and slide it away against the panel..The secondary tin plate is removable(if you need to remove it), two clips super close to where the sets of wires come around the housing and into the panel. Unhook the 4 plugs(blues and pinks)...Now lift the power housing off of the panel. The big board has the power. One screw to remove a ground plate first. Two screws to remove power board. Pics from phone.56ec44b.jpg
aae8fab.jpg The capacitors top-plain should be flat(not rounded) and there should be no color whatsoever coming through the top of the cap lines(google "bad capacitors"). The specs of the cap are on the cap. The 2 caps cost me $4.00. Now keep in mind there are hazards to this.Google them;)

Gateway LP2207 64 bit drivers

If you can't find the drivers anywhere else, do this: There is a UL Code listing on the back on the monitor's electrical ID tag on the back label. It has a number on it: UL (number). Go to the UL site and look up the number, it will tell you who actually made the monitor for Gateway. (Gateway doesn't
make monitors, it rebrands them.) Go to the mfr's site and download drivers for the monitor of the same size as yours using the 64 bit drivers. It will take a bit of slouthing, but can't be done successfully. (Ex. Sampo is actually Hitachi.)

It sound like your auto display setup menu is appearing on the monitor. If so, it probably says to press 1 or 2 to stop the display. If this is the case, then the #1 and #2 it is referring to are the buttons on the monitor-not your keyboard. If you look closely at the monitor controls, you will see that at least 2 of them are numbered.
Let me know if this is the correct problem.

Hitachi Monitor turns on for a sec then turns off.

Since you have already indentify that the problem is with the monitor, next thing to do is to open it up, but if you are going to DIY repair, then you should read below and look at the pictures so you will know what to look for inside.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My hitachi 15.4 inch laptop monitor is not working, i can read and see everything but its very dark so what is the problem and how can i read it clearly?

You should first try to increase the screen brightness by holding down your function key and hitting the screen brightness key. If you have tried that, borrow a computer monitor, and connect it up to the VGA output connector on your laptop. If you toggle to an external monitor, by holding the function key, then the monitor key, you should be able to tell if the video is bright on the external monitor. If it is ok, then your laptop has either a bad LCD inverter, or backlight bulb.

My LCD monitor has a dimmed display

You should be able to increase the brightness by holding down the blue "FN" key and finding the blue brightness buttons (usually the up and down arrows or two of the F keys above the numbers. The brightness buttons usually look like a sun with a up and down arrow.

Hitachi CML174SXW B randomly goes black

Have you noticed if the monitor gets hot before it turns off?

Please, don't open a monitor and try to repair it yourself. It can be very dangerous and it's not worth getting injured.
