I plugged in this monitor and it showed the green light but then it just clicked back to yellow. it did this 3 or 4 times then it would not even show the green power light. my sister brought me this monitor. by the way it is a flat monitor.i did hook up a 17" dell crt monitor to the same computer and it worked fine. the computer has a 220 volt psu as do all my older cpus. i have not added anything new to them either. i do all my cpu tinkering in one of my bedrooms. so i can't imagine any type of magnetic forces messing with my eguip. are 220vs enough to run a crt but not an lcd? flat screen? can anybody help me with this sit.? i mean are their any indications other than black screen and no power to say this monitor is bad? Thanks for any help i can get in advance.

Rodsupply - welcome to the PC World forums. You mentioned that your sister brought you this monitor. Is it a new monitor, or a previously used one?

Since you mentioned the 220 volt power supply, I must assume that you are in Europe. But to answer your question about the power required to run an LCD versus a CRT, the CRT will consume more power, but both will run from the default household voltage in the area where they have been sold.

Does this monitor have only the VGA input or dual DVI and VGA inputs?

Hi, Rodsupply. And welcome to the forum.

Have you tried running the monitor with another computer?

no i have not tried this monitor with another computer. also to the other guy no i'm not in europe, i'm sorry if i misled you to believe that. i meant that the psu in the computer was 115-220 volts. the only thing i can find on the back of the monitor is 12v 4amp. i'm really lost as to what it can be. also yes this monitor was used. not sure how long ago.thanks guys for any help. rodney

Ok, yes, you have a switchable power supply in the computer, but if you are in the North American market it should be on 115. The monitor should have a power brick if it runs on 12V. Some monitors have internal power regulators so you plug in 120v standard, but some also have an external power brick similar to what laptops have. That plugs into the wall or has a standard power cord and then the low voltage plugs into the monitor. The larger external hard drives and some printers also have the external power bricks.

thanks again rgreen for your help, i only see the dvi. in order from left to right this is the back of the mon., pc-in, dvi-in, av, pc, dc-in,. then under the av,pc it shows audio in, then to far right it shows video-in, s video. ok the power brick is a wall plug-in type 12v, other end plugs in the back of mon. like a phone recharge cord, with round plug-in.ok, assuming the power is right, are they any other troubleshooting things i can do? thanks again. rodney

Alright, the PC connection next to the DVI should be a D-shell plug with three rows of holes, and the center is probably blue. Is this correct. This connection is what we call the VGA connection or analog video. It has been the standard for PC to monitor for over a decade. Starting about 6 years ago, the DVI is a longer connection with 24+ connections and the center should be white. The various connctions in the 24 pins (2 rows of 12) are digital signals. AV could be three single hole connectors red, blue and green if it is component (digital) or a single yellow connector if it is analog.

Have you asked your sister what she had it connected to last, and what type of connection?

How long since it has been used?

As for the power, if the block that plugs into the wall is a standard 115-120 style US connection, the power should be good.

Is there a button on the bottom or side to change the input or source?

From the plate on the back with the makers name, what is the model number?
