HP 2009m - 2 seconds to black

[redbox1]

Hi,

I have HP 2009m monitor that is suffering from the 2 seconds to black problem. A couple of times it has stayed on a bit longer but it hasn't done that for awhile.

I went ahead and changed all the Elite caps except for the very large one. I haven't changed the four rubycon capacitors (top center).

So far I've found that Q901 (P10NK70ZFP) is showing 3 - 102 ohms for a couple of seconds but only with black on pin 2 and red on pin 3. I'm not sure if that means it's bad or this is the way it's supposed to be. I've attached the datasheet for it, hopefully someone with more knowledge can let me know.

Thank you for any help and advice. I hope the picture quality is okay, my camera doesn't seem to want to do close ups.

Thank you again!

Fixed many of this model with same problem: burnt lamp's wire. Cheaply made monitor, some will run for hours before it goes black depends on how good the wires are hanging on to the lamp's end.
Not easy to disassemble the screen either, you can easily break the lamps.

This is a somewhat old post, but I'd like to get a little more information from 'between the pictures'. The images show you finding the bad wire, which is more than likely the correct diagnosis for my monitor as well as it starts up and then goes to sleep mode or black out after a second or so showing my desktop-- and I was hoping you might explain to me how exactly you replaced the wire. Did you order something from online, or did you have the parts laying around from other lcd screens?

The black and the blue wires stick to the frame with sticky tape, you need to carefully lift the wires, the on the other end of the wires are enclosed with black shrink tubing that you have to remove, one you do that you will have more wire slack to allow you to solder the wire to the end of the lamp.

This is very delicate operation and you can easily break the lamps.
