Monitor loses screen after 5-10 mins and then 5-10 seconds

Sounds more like the transformer's getting overheated/shorting internally. If you unplug it and leave it off for about 10 minutes, then plug it back in and get the 5 minutes of working video back, then I'd suspect it's heat related and something's breaking down internally.

Screen is tinged yellow

It sounds like you're going to need a new VGA/DVI cable. (from PC to monitor)
I suggest you try another one, then post back here if it doesn't fix the problem.

I hope this helps,

I installed w1907 monitor all fine except now I have no sound

DVI is a hardware interface. It's a type of plug.

Does your monitor have speakers built into it?

On many computers, the output for the sound is very near the output for the monitor. Is it possible that you loosened the wire for the sound when you installed the monitor (plugged it in), or unplugged the sound altogether and plugged it back into the wrong place? The outbound sound hole on most, but not all, computers is green.

All computers have at least two places to plug in sound, most have 3, and the newer machines have 6. If you are unsure which is the correct hole to plug that sound wire into, you can play something on your computer that makes sound for a while (like a song) and move the plug from one to the other until sound is heard.

If you have 6 holes that the sound wire fits, you most likely have software on your computer that pops up and tells you were you have plugged it in.

If the speakers are built into the new monitor, check the monitor for controls and ensure that the volume controls are not all the way down.

All of these solutions are hardware solutions. Now, we have software solutions:

Open the control panel and find Sounds and Audio controls. Open that.

Check to see that nothing has "mute" checked.

Check also to see that the sound levels are high enough to hear something.

Good luck.

The volume is too low on my computer speakers

Hi, Mark Here, see I can help.

The 1907 does not amplify your sound it will let you control the volume to some degree but not boost the incoming sound.

If you had amplified speakers b4 your sound card requires amplified speakers.

Best two options i can give is.
  1. If it is a desktop you can install a amplified sound card. Hook to monitor speaker.
  2. Unplug monitor speaker &use amplified speakers.
Just so you know laptops use internal amplified speakers. If you decide to install sound card make sure it is an amplified card.

Hope that fixed ya! know not the best news. Need more help comment back. Please Rate.
Good Luck!

EN9250 worked graet 20 minutes ago. Unpluged it to move computer- Plugged it right back in and now no signal. I have checked all connections and still no signal

Make sure the cable is plugged into the video in. Shut down the computer and unplug it. Unplug you monitor again and also check conections by removing the cable make sure no pins are bent on the monitor or the conection to the computer. Plug all back in. Turn the monitor on first and then the computer. I hope this helps. If not let me know I will need so more info. Good Luck.

No Sound

Make sure that it is not mute, also make sure that no sound cables were unplugged. Your sound card driver might have unistalled.

Go to your sound card's manufactorers website to download the driver

i have some 19 inch medion monitors that have the same problem .. they make a lot of noise and the screen might be jittery/fuzzy ... i found the following:

several capacitors in the power supply (inside the monitor) had their tops buldging .. that shows that internal pressure was high in the caps, usually caused by them being hot and thats caused by high internal leakage .. the caps may eventually blow out the tops (explosion vents) .. the caps are designed to do that instead of becoming a bomb ..

all the bad electrolytic capacitors i have seen so far on these monitors, motherboards and other electronics have been chinese made .. they made millions of bad caps over several years ..

almost all the bad caps had buldged tops but not always .. once in a while i see one thats open but not bulbged .. probably venting elsware ..

i changed the obviously bad caps and the monitors returned to like new performance ..

i dont know about the 17 inch but the 19 inch medion flat pro display is not too hard to take apart .. about 30 screws or so ... speakers have to be unscrewed and you have to be careful not to stress cables that go to the push buttons .. of course you have to know how to solder without bridging paths
