Have you tried plugging it into different electrical outlets? Also, are you using an extension cord and/or a surge protector?

I would suspect a faulty Zener or Diode, transistor, allowing dirty DC or AC ripple, to the Caps.. use a scope and have a look. One must always find the cause of why things fail simply fixing the symptoms simply means it will fault again.

Open lcd 17 power supply 5volte ok 13 dimming

First of all you need some electronic repair experiance,
You have to disconect all f the power supply that going on 5v(rgb processor in moust cases)and 13v in most cases ccfl inverter(back lite ) with his driver.than have to mesure the voltages.
-Replace the capatitors in 13v line.
if the problem persist try to replace the diode one for 13v with one for 5v,they should be the same type.and check the voltage 5v and 13v.
if the problem is still on 13v look for the problem on the 13v line.

Usb powered aoc monitor is blinking


Active USB cables boost the USB signal not the 5v power lines. After about 6 feet the 5v power lines will only provide 4-4.5 volts and this is not enough to power the monitor. For this to work you will you will need to also use a powered USB hub at the remote end by the monitor. The USB hub will supply the power and the monitor needs and the active USB cable will provide the signal.

My monitor power on then cut off what can i do

Hi there,
I had the same problem with the exact same model of Gateway 19" LCD. Likely this is the same issue you're experiencing, and I hope you're able enough with a multi-meter and soldering iron to fix this issue, or willing enough to tear this thing down to its components and at least try to fix it.... otherwise you have a fancy dead-weight object on your hands/desk.

In my case, the 5V power was fried so I actually inserted a 5V 2A power supply inside the monitor housing and soldered the +5V and GND leads to the marked connector pins that connect the power board(larger) to the vga signal board(much smaller). I stripped the guts from the 5V power supply so it would fit easier, and then stole power from the 120v monitor input and directly wired that to the wires that were hooked to the 120v power supply prongs(after removing those prongs as well). The monitor looks and functions as if it were brand new, there's nothing extra hanging out and no bulges anywhere. It works excellent.

Aside from my more-so hackful approach, here's some links and quotes, from other sites, from people who know what components to replace on the power board and still achieve a well-working end result.

Model no. TFT1560PS,LCD monitor,.. upon pluging or opening it, the light will bink only at two times, and then lights no more. but the object or the letters are still there.

Open it up and chaeck to see if you do have 5v and 12v in the power supply, check to see if you get the 12v all the way to the inverter circuits, also look for bad caps, see examples here:

No triggering

Hard drive is most likely dragging the 5V circuit down. Download a free Mepis CD and pull the drive to see if it will boot and run on the fly..

No Power in Monitor

If you are a tech. Check the voltages going to the Logic Board, if one is missing (12 or 5v. Then that is most likely due a an IC failure on the power supply board. IC 901 Don't quote me on this, but I know it is less than $10. Sorry, I only have 1 left, the last one I did was in Aug2006 so memory is fuzzy. Kegtapper
