Question about Computer Monitors

LACie 319 LCD 'smuge'

The monitor, when on and heated to normal specs has a smudge or smear . It's at the top about .12" down, across about 6" of the screen. What ever color I choose for the background the smudge takes on that color being darker; that's how I see it. I have attached to to 2 different box's, used both the analog and digital connections, still there. I was able to take a picture of the anomaly, talked with LaCie, sent it to them. They set it up and can not see anything wrong with the monitor.
I have used the cables on a different LCD monitor but no strange smear.
They want to send it back to me.
I called today and asked them to do a rigorous power supply check. I thought it may be a 'weak' power supply: thinking that LaCie's power in there shop is FAR better than mine in my home office. I have run a dedicated home-run to the main box at HO to connect my equipment.
OH yes, the small icons on the LaCie are not nearly as clear as the ones on the other monitor.
I am using native resolutions and speeds.
Any ideas?
thanks for your time,

Re: LACie 319 LCD 'smuge'

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

I need an internal pin out diagram for a 4 Pin connector to connect power supply to a hp pavillion f70 monitor. I do have a power supply with same specs but it has a normal plug with outer as +ve and Inner...

12 VDC , 4.16 A (4,16 A) Frequency: 50/60 Hz Power Consumption: less than 36 W in operating mode.
I think the other two pins are not used. It just requires the 12 Volts DC. +ve and -ve, positive and negative, respectively.

It's a Viewsonic VX715 Monitor. When it's turned ON, It goes black in 3 seconds.

It can be one of thses: bad caps (bulging top or bottom seal) in the power supply, bad backlight inverter circuits, bad lamps. You need to open it up and lool for bad caps first, then measure the voltages across the filter caps, you should have 5vdc and 12~18vdc (there are two power supplies: 5vdc for logic, 12~18vdc for backlights citcuits) Post back what you find so we can guide you further, see example of failed VIEWSONIC monitors due to bad caps:

Image rotation,

Paul, will your computer is on, close all applications, go to a blank area on your desktop (where there are no icons or shortcuts) and Right-click, a drop-down menu appears, go down to Properties, a window will open, across the top of the window go to the "Settings" tab, then at the botton right click on the 'Advanced' button.
Now, here is were it can differe from machine to machine - the tabs across the top normally will have an Adapter tab and maybe a specific tab to the video card in your computer. At first I would click on the Adapter tab and in here you may find a setting for rotating the monitor image for Portrait or Landscape, or there may be another button like 'Properties' that will take you further into the video adapter settings and in there you may find the rotate settings.

Do this. With one of the windows open instead of using the square box to enlarge the window, use the mouse cursor to drag the corner of the window out to the size you want. Then close the window by hold down the Control key while clinking on the X next to the square box. The next time you open this type of window it should be the size you want.

LCD monitor image

I just had the same problem! Was afraid I needed a new video card. (--a suggestion found on another forum.) But a friend suggested a low tech solution. After turning the computer off, I opened the CPU casing and blew pressurized air inside to clear the dust out and the problem went away. Hope this helps.

Blurring of images and text

mt, the 6 to 8 lines you were seeing were most likley the prelude to the end of the monitor. If the problem only occurs when the screen saver comes on then I could say the driver maybe being corrupted by a certain screensaver picture or program. When the monitor warms up to a certain temprature the electronics start to fail. You may want to turn off the monitor while your not right in front of it to cool it down and prolong its use.
