Re: HP 2159m - No signal issue

Decided I might as well attach an up-close picture of the traces near the conncector and missing capacitor....

Re: HP 2159m - No signal issue

A little thing I over looked, for some reason there is a missing capacitor (C854) on the top right of the power supply board in my top veiw, bottom right in the bottom view attached. Looking at the traces, it went between the Gnd and VADJ (voltage adjust?) pins on the connector. Any ideas what it is for?

Also, I am about 99% sure I am the only person to have opened this display before, I did not notice a cap floating around in the case, and I did not notice any caps break off while I've been working.

Also, as the bottom...

I recently aquired a HP 2159m monitor. The monitor will turn on for a short period of time after having a video source (Can be HDMI, VGA, or DVI) and AC power plugged in, it will display a menu that claims it cannot detect a signal from any of the video sources, then the display goes into stand-by.

So far, after reading a few threads about this monitor and general trouble shooting:
- I tested the fuse on the power supply to have no resistance.
- The large cap on the powersupply has ~160V across it.
- The +5V leads from the powersupply to the mainboard measured...
