W2207 hp reset to factory settings - HP w2207 Monitor

SOURCE: I have a HP w2207.

Hello,

First of all test if the monitor outputs anything when you boot up the pc. That particular stage is done at lower resolutions (usually 640x480, 800x600 etc). This way we can rule out a problem with the monitor being unable to scale higher resolution due to a video processing error at hardware level. If the monitor still can't display anything and you know the pc's video card to be working (tested with another monitor, for example) then you may have a hardware problem with the monitor itself.
Some time ago i've worked in a HP authorized service center, but I've retired from there a few years ago. Surely monitor technology has changed a bit but basic principle remains the same. One possible flaw could be related to the logic board inside the monitor. When you plug a vga/dvi/hdmi (any type of signal) cable to a monitor, it's logic board - mainly the cpu inside, should sense the connection and enable a power on voltage to the lvds bridge supplying the lcd panel (screen). If this voltage is not being sent or is not stable enough, the monitor will either not display anything or simply go to stand by when you insert a signal cable to it.
If by testing the monitor you cannot make it to display some sort of image, in any resolution, you could try sending it to a local service center - if warranty doesn't apply to it. Please tell them to check the logic board and lvds processing system. Also bad, broken or high ESR electrolytic capacitors in the SMPS power supply inside the monitor could cause this problem, they would also need to check them and replace if needed. The actual capacitors are cheap, let's say about $5 for all of them, but if the logic board / CPU has died or malfunctioned, that could get more expensive.

Sorry for not being able to give a more pleasant solution.

Testimonial: "You had some great Ideas on where to llook. I can replace the cap if I find any bad ones. I can also replace the logic board if I deem that to be bad."
