My Soyo 19" TFT monitor Model:MT-NI-DYLM1998 comes on at power up but goes black after a few seconds. But on repeating turning power off then on again, the monitor comes on and then goes black again after...


Thank you for answering those questions. That usually indicates it has a bad power inverter. From what i can tell, that monitor is a few years old. You can attempt to find an inverter online to replace it yourself (usually about $50 if you can find one) since its no longer covered under warranty, or put that money into getting a new monitor.

My AOC screen goes black after about a few seconds after booting.


Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

The light comes on for A few seconds amd goes out. The back light comes on for A few seconds dimly and goes out how do you open the monitor and fix it?


Here are the free service manuals: http://elektrotanya.com/?q=showresult&megnev=ACER&megnev2=AL1917&kategoria=&kat2=schematics

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Video cards that can handle two monitors at the same time have cables with two plugs on the monitor end.

If your video cable has two plugs on the monitor end, try the other plug.
