Re: Asus VH242H: 2 seconds to black..

Power supply board by itself sees 3.5vdc at those two spots.

Re: Asus VH242H: 2 seconds to black..

Correction. Now the vdc in those two spots reads 2-3vdc. Did i just break that damn thing?

Re: Asus VH242H: 2 seconds to black..

9945N AABY05 on both.

Also I have a new problem. I was reading the 2 second to black guide thread and was going to test CCFLs (without a spare). When I put the monitor partially back together to test them, I plugged it in and the power button doesn't work. The LED does not light up when I click power on, and the monitor does not turn on. I think unhooked everything and hooked it back up again without the LCD screen (like I had it before when I was testing) and I can't seem to get the power button to work again. The inverter board...

Re: Asus VH242H: 2 seconds to black..

Ignore what I just said. The DC voltage between the two points you asked me to measure is 17vdc

Re: Asus VH242H: 2 seconds to black..



Ok, I made a mistake while measuring it. I was measuring vac. The WHITE rectangle box on the right is reading 17vdc while powered off put plugged in, and the little square WHITE box is reading 0vdc while powered off but plugged in. As a side note, I am not sure if it matters, but on the other side of the board, there is nothing soldered into the A2 point (the left point you had me test).

I am fairly new to this. So I wasn't sure if I was testing the resistance correctly. But the resistance between the two points...

Re: Asus VH242H: 2 seconds to black..

When I have the multimeter touching nothing but air I get a reading of 0.06V

In the first pic-
The YELLOW box has everything at 68V.
The RED box has everything 0.03V, including the WHITE boxes that I just tested, but those two points you asked me to test jump to 0.5V when I switch inputs, and then after 2 seconds drop back down.
I noticed in the BLUE boxes there was a constant voltage of about 0.5V and it would drop to 2.5V when the monitor would change input.

The other 3 pics are of the top of the...

So I have been spending the last 24 hours trying to figure out how to fix my monitor instead of having to buy a new one. I have done a little research, but need some clarification on things. Keep in mind, this is all very new to me and I am learning as I go. I have some experience with electricity and circuit boards from growing up, but I have forgotten most of it.

The symptoms -

When I turn my monitor on, it shows a great picture for 2 seconds and then the backlight goes out. It does this over and over again. I am able to see the screen when I shine a light on it,...

Hi,

My name is Chris. I am a graduate student studying Biomedical Sciences and am trying separately to fix my gaming monitor.
