Question about Hitachi CML174SXWB (Carbon) 17" LCD Monitor

1 Answer

Hitachi Monitor turns on for a sec then turns off.

I have tried switching out power cables and go over to another outlet but it still will not turn on. I have 2 Hitachi Monitors which i am using them both dual monitors. The one that is not turning on is monitor 2. I have already hooked up another monitor to the computer and monitor 2 works.

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: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

How to fi a phillips 20fp shuts off in 2 scs.


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Power is on but monitor does not come on


check the cable, wiring harness, check the outlet for power, make sure you do not have it is a plug that may have switch some where where it turns or shut the power to that outlet.

or can it be video card issue, or plugs adapter is faulty, try a different outlet or different plug in your power strip. check the power strip if you have one, make sure the power strip is on, push the reset button on the power strip.

if you motherboard has internal vga adapter try setting resolution to the lowest setting plug you monitor into the motherboard to see if the issue is the video card or cards.

turn monitor off and on see if it getting warm.
the resolutions maybe to high try lower setting temp.

see if the monitor has manufactures restore or reset button on the monitor some where, it would be around all the connectors are located.
does the light comes on when you turn on in the front of monitor.

if all fails than it is time for a new one.

thank you rod

It wont power up bro


It is possible that your monitor is on a GFI switch. These switches turn off if they detect a problem that could incur a shock, or if they are getting worn. Check if there is a power outlet in the same room with a red and black switch. If so, push the reset switch, typically the red one.

Your monitor may also be on a switch activated outlet. Is it plugged into the top outlet? See if a wall switch nearby controls the outlet. then try turning on your monitor.

Is the surge protector your monitor is plugged into turned on?

Check the cord on the back of your monitor. It is possible it may be loose. Plug it in all the way.

Some Viewsonic monitors have a power pack that is not inside the monitor case. Check the wiring between it and the wall and between the pack and the monitor for frays.

Below you will find my recommendations for troubleshooting this issue:

1. Reseat the power cord and verify a good power source.

To reseat the power cord, follow the steps below:

1.1 Power down the system.
1.2 Unplug the power cord.
1.3 Wait approximately one minute.
1.4 Reseat the power cord.
1.5 Verify that the power cord is plugged directly into a known good power outlet.

2. Verify that the monitor is receiving power from a known good outlet and bypass any power strips.

To test the power outlet, perform the following steps:

2.1 Unplug the monitor power cable from the power outlet.
2.2 Plug in a different device, and verify that the device is operational.
2.3 If there is no power try another outlet. Remove any power strips and try plugging directly into the main power outlet.

3. Verify the monitor is powered on and the power button is engaged.

Ensure that the monitor is powered on and that the power button is fully engaged. To do so, check the power LED on the front of the monitor; it should be lit.

NOTE: There are two types of power switches:
A mechanical switch characterized by a long travel. You have to push it further and you will hear an audible click.
An electrical switch that has a short travel and almost no click.

A lit monitor LED can be any of the following:

* Green
* Blinking green
* Yellow
* Blinking yellow
* A combination, such as alternating green and yellow

Any of these states indicate the monitor is receiving power and that you should proceed.

4. Swap power cables.

To try a known good power cable on the monitor, follow the instructions below:

4.1 Turn off a working monitor.
4.2 Unplug the cable from the back of the working monitor, and unplug the cable from the wall.
4.3 Unplug the cable from the monitor in question.
4.4 Plug in the cable that came from the working monitor.

5. Run the monitor self test.

To run the monitor self test, perform the following steps:

5.1 Power off both the computer and the monitor.
5.2 Unplug the video cable from the computer or video card.
5.3 Reseat the power cord to the monitor, ensuring it is plugged into a known-good outlet.
5.4 Power on the monitor.

NOTE: The monitor self test will move around on some monitor models. If the monitor self test moves, allow it to move to the affected areas of the monitor to check for the problem described.

If the Self test failed, it's possible that the monitor is faulty. Contact dell to check if it's still under warranty so they can replace it.

Try to separate the power cord of your monitor from your system or maybe if your using UPS(uninterrupted power supply) directly plug the UPS to the wall outlet. either you can use pretty voltage regulator to the regulate the AC power.
if not solve the problem try to examine the your system power supply.
