    The backlight inverter has gone pop. Does anyone know where you can get a new board. Syncmaster 152V

     I have the same problem and would like to fix it. Seems do-able. Have you found the solution? I read that it could be capacitors. I would like to know what you did to resolve this problem. Thanks

I got the same problem. There was two capacitors (1000uF/10V and 220uF/25V) on the power module which was dead and a blown 3A fuse. After careful check I found one of the transistors on the inverter circuit was short. There are 4 transistors each in 8 pin SD (SOP-8) packaging with marking 4600 on the 1st line and BD3Z4P on the second. After some searching in internet I realized they are ELM34600AA-S complementary MOSFETs and still can't find a delivery to my town. I believe after MOSFET replacement the monitor will go well.
The transistor was shorted between 3 and 5+6.
Here is the datasheet: http://pdf1.alldatasheet.com/datasheet-pdf/view/308736/ELM-TECH/ELM34600AA-S.html

Desktop computer monitor goes black but works on other computers


It sounds like the resolution is set wrong. Go to the minimum and see if that solves the problem. If so keep working up.

My monitor won't stay on it will go black after a sec. If you turn it off then on the monitor will work for a second the it goes off again. I have unplugged cords and it still does it. I have a hp f2105


It is "normal" for a monitor to "go black" when it is NOT connected to a computer.

Connect it to a different computer, to see if the video-card on your computer has failed, and to see if the LCD monitor works at all.

The 470uF 25 Volts capacitors on the power supply board are probably bad. Replace them all and tell us the result !

Hello!

I see many monitor with that trouble.
When you turn on comp., you can have a picture on monitor about 10-30 min. and that go in black screen, or If you change resolution again go in black screen.
You must repair monitor or bay another.

Monitor black screen


Your first step in troubleshooting this problem is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is shot.

Monitor goes black


Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!
