SOURCE: LG screen goes in stand by.

oke having a similar problem atm, this is what i have found so far. was trying to help a friend who has bought the same 19" LG monitor. When i connected the monitor to her PC i noticed that it was not the same connection as the previous one but it had the smaller blue connection..this shouldnt be a problem but it was. The monitor when powered up, showed LG logo then went into power saving mode. My next step was to try the monitor on my own PC to make sure it was working, When i did this the monitor got a signal but on the initial boot it did say that this monitor was not compatible currently the way i had it set up ( where i had it plugged in? the only place it can be) because of my graphics card. oke so atleast i knew the monitor was working and was recieving a signal.

the only difference i can see is when i put it in her PC it is not giving me this information which also did give 3 steps to solving the problem but didnt seem legit. the next step i will take is to try my monitor on her PC although im not sure i expect it to work.

i think it must be a) PC is now faulty or b) PC is not sending a signal to the monitor ( possibly due to the fact it is not the same connection as before.)

what i have seen on other similar posts says you should also listen for your PC starting up normally.

another thing i would like to know i think it can be usefull for this topic. are the people who are experiencing this problem in the same situation as me i.e. changing the type of connection used by the monitor from the larger to the smaller type?

id also liek to note that the monitor i have was bought on a tight budget from PC world.

only other help i can give to people with this problem is that it is much easier to see where the fault is when you have 2 PC's and 2 monitors i know this is not viable for many but if atall possible interchanging parts with the PC that is working correctly and the one black screening can help you see exactly what the problem is,

as far as i know aswell the main reason for a monitor to sleep is that its simply not getting a signal from the PC BUT on rare occasions it can be a fault in the monitor. IF you have another monitor with the same connection that you can get yto work on the same PC its the monitor with the problem, if u have a monitor that u know is working on another PC with the same connection but is not working on the PC in questions its a PC fault.

sorry for the jumble of words in this answer i tryed my best to explain, all my knowledge of PCs is from friends and self tought so ... hope it helped

Hp flat panel monitor comes on shows logon and then blank screen


Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on?
If stays on, then inverter turns into protection mode because of old backlight lamps.
If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.

Monitor turns off after about 3-5 seconds


I would say your monitor is bad if you have tried it on 2 different monitors and it does the same on both. Check your warranty expiration date, some monitors have 2 or 3 years warranty. If it's still under warranty, you may be able to have it replaced or repaired.

The l226wtq goes black


Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.

Proview monitor won't keep the screen on


bzinbby1, Hi, I think I know what's wrong. In fact I already know what's wrong! But I want you to do one test to let me know how bad it really is! Here is the test. I want you to reconnect your Proview to an already fully booted "KNOWN GOOD" pc with WIN DESKTOP showing. Then and only then power up the Proview and hold a good, bright flashlight 2 inches from the lcd screen after the screen goes to BLACK! Even though the screen appears BLACK, can you still see the WIN Desktop if you hold the flashlight at different angles???? Get back to me with results of test. I will then tell you what options are open to you as a consumer whose screen is now dark and lifeless. I'm louie12fix on fixya or lmistyrel@ aol.com
