Question about Mag Innovision LT782S 17" Flat Panel LCD Monitor

1 Answer

My screen has been going black

It goes black after 10 seconds and stays black. I thought it was my cpu but I was fooling around with the on and off button on the monitor and walla, it came on. It came on for just a few seconds and went back to black. I juggled the power switch and it finally stayed on. At least I won't have to lug my cpu out. Do you have any suggestions on how to permanantly resolve this issure?

Thanks,
Don

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After went black, you have check if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like mine, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

Iphone 5s is locked and disabled and stuck on connect to itunes


Dear Sorta,
Please follow below instruction:
Turn it off by holding home+ power button untill the screen goes black ( as soon as it goes black, release the buttons).. This might take some practice , so dont worry if on the first try your phone reboots and goes to itunes screen again.
Now, with your phone powered off, enter DFU mode:
Method 1)
  • Attach the phone to the pc
  • Turn the phone off
  • Hold power and home together for *exactly* 10 seconds
  • Release power but keep holding home until the pc beeps as a USB device is recognized.
Whilist in dfu mode, itunes will recognize the device and it will ask you if you wish to restore it. Simply click restore, and the restoring proces will begin.
This will hopefully fix your iphone.
Cheers

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

How to activate the front camera on the pantech ease?


I also thought the Pantech Ease had a front camera but what has been call a front facing camera by some is actually a sensor that detects when you have the phone up to your ear.

The sensor is that small round hole you see under the glass just to the left of the ATT logo and the ear speaker. Try making a phone call to your voice mail. You may not have noticed that the screen goes black when you place the phone next to your ear during a call. (this helps save battery life) During the phone call take the phone away from your ear an in 1 or 2 seconds the screen will come back on with menu options for features you can use during a call.

Now test the sensor by placing your finger tip over the sensor hole. The screen will instantly go blank. Remove your finger and the screen comes back on. Put your finger on the glass to the Right side of the ATT logo and the screen will stay on because that hole on the Left side is the sensor.

Like I said before, some sources describe that sensor as a camera which is only half true. Unfortunately I was also fooled by this misinformation. I was hoping to have a front facing camera to use with Skype. I was a fool to believe their hype.

Getting message error -40 cant connect to itunes on my ipod 2g a1288


1. First, Open up iTunes, plug in your iPod Touch/iPhone to the CPU's USB port. Turn on your CPU's speaker and make sure it is loud enough that you can hear it.

2. Hold down the Home button (top left for iPod Touch and top right for the iPhone with the screen facing you) and the Power button (located on the front bottom of your iPod Touch/iPhone) simutaneously, until the screen goes black and the device turns off. (past the red slider/slide to power off screen)

3. Now let go of the Power button, but continue to hold the Home button. Your iPod Touch/iPhone should have turned off and the screen should not be on.

4. After around ~10-20 seconds, you will hear a noise (beep/ding) from your CPU as if it had just recognized a new hardware device, now iTunes should recognize it in DFU mode.

5. After iTunes recognizes the iPod Touch/iPhone, let go of the Home button otherwise it will go into recovery mode and you will have to do the entire DFU process over again.

6. You will know when you have put your iPod Touch/iPhone correctly into DFU mode when the display is blank and that you do not have anything on your device.

7. Restore ipod using itunes

Monitor goes blank less than a second after turning on.


I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.
