Why did my computer monitor stop showing an image?


Disconnect it from computer and power. wait 15 minutes and plug only the power back in, press the power on button. The monitor may display a message that there is no signal or something like that. If that happens the problem is either the cable or the computer. If you get no message then look for the menu button and press it to see if any thing appears. If not find the manual on line and read it. Many times monitors get over-driven by computers to the point that they can't display OR they self destruct.


OR

Another way is to just unplug everything computer and monitor for 15 minutes. Plug in monitor first then plug in computer and press the power button, the display should display the booting information if the cable is good and the monitor is good.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Blurred image in Samsung Syncmaster732nw monitor


For best pictures, you need to set your PC video resolution to the native resolution of this monitor, which is 1280x1024 @60Hz. Try that first before opening up the monitor to look for bad components.

My Lg Monitor wont show screen (Power Button Flashing)


The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Bright,thin line, in the middle of the screen, then...


1. I turn on the monitor, I hear a 'cracklin' sound
Reply: In a CRT Monitor there is a component called EHT which generates High voltage which is connected to the anode of the CRT, If there is any leakage due to moisture can cause this crackiling sound, You need to clean this high tension wire or replace the EHT ( CAUTION : BE AWARE OF HIGH VOLTAGES )

2. The screen only shows a bright, thin line.
Reply: The vertical Drive section of the monitor is faulty.

Base on the information given to me.

I think your computer is on sleeping mode.

first thing check if the video cable is not loose connecting the pc.

because what would happend, if it is loos it would turn on and off at times.

The other thing you can do.

right click on the desktop.
go to properties
go to screen saver
click on power

adjust the time you want your monitor to shut off.
