This problem requires you to test both the monitor and the signal input form you cable tv setup. Set the monitor up on a computer and see if it works properly. If it does then you may have a problem with the signal conversion of the cable tv to the monitor. It also could be a weak signal that drops below the monitors sensitivity levels. Have your cable tv repairman check the signal levels on your lines. Another way to test this is to hook up is with a different monitor to test your setup and see if it works. If after testing you find, the monitor does not work properly, then you need to have it serviced. Hope This Helps.

How can i play ps2 on lcd without having a black and white screen ? how can i connect the cables ?.....when i look at the back of my lcd i find three ports (red white yellow) when i use them the screen is...


1) The set of input (Yellow= Composite video, Red= Right channel audio, White= Left channel audio). This set of input is for composite video.

2) The set of input (Red= Red video signal, Green= Green video signal + sync, Blue= Blue signal, Red= Right channel audio, White = Left channel audio (the Red and White will be grouped close together). This set of input is used for Component video for HD signal.

You should try using composite video source (Yellow RCA jack) from DVD player and feed to the monitor and see if it works OK with all color showing that way we acn find out if it is the video source problem or the monitor video signal processing problem. Try the PS2 on the TV if it works OK also.

No signal from computer after Windows XP loading screen comes up: when I turn the computer on, there's video signal to the monitor, but once it gets to Windows loading, it stops and goes black.


Does it do the same when you bootup in safe mode (hit f8 key while booting up)? if it is OK in safe mode, then it is software problem, not hardware.
Post back what you find.

My monitor ( with less that 6 months use) has been going off while someone is using it--- says out of signal and i have to restart the comouter... and this is not stopping even with a restart


julezj, You will need to connect your monitor to a KNOWN GOOD pc that DOES NOT have the screen saver set to do a time out when the keyboard is inactive. Whenever you state a problem with a monitor on fixya, please mention the monitor technology you are dealing with. CRT (TUBE) or LCD flat screen!! IT HELPS IF WE KNOW TOO!!! Did it really display a screen message that read "out of signal" or did it read "OUT of RANGE SIGNAL"??? Is this monitor used to display HIGH resolution gaming and other high refresh rate imaging? Will this happen if you only have the WIN-desktop showing on the screen? Get back to me with more CLUES as to what happens on the screen. 12fixlouie Bye for now.

The monitor screen goes dark about 10 minutes


Please verify the power option setting present in 'control pannel' option once. If you have selected to turn off the power supply after 10mins, (once the system is in idle state) then the SMPS will stop supplying power.

thanks.

MONITOR BLICKS AND NOTHING COMES ON THE SCREEN


Grateful how? Neverminding that detail, perhaps your screen's backlight or the power supply for it has failed. There's nothing to do but compare your unit's operation with that in the Service Manual or that of an operating unit; this is complicated by the fact that components might send an OK signal back to the main controller, so removing the bad parts will not necessarily mean the unit behaves normally otherwise. It may be as simple as rinsing the cat barf out with water and D.I. water (but you would still have to open the thing up on towels to find out.)

Of course the main power supply might also be faltering. you can probe the supply (with a DVM or scope) to see how steady that is.

Lack key appear on my flat screen


Do you use the remote control or buttons on the tv itself? Many TVs have a child lock feature that will prevent operating the TV without the remote control. If you use the remote control you should be able to change chanels, and to disable the child lock from the menu.
