Re: HP ZR2740w almost dead
Hello all!
I have this very same monitor on hand, started blacking out erratically at work, got replaced and brought it home. Soon didn't work at all. Blue light for a few seconds, then amber. Didn't get any voltage readings measuring the LED-connector. On the P803 the 5V is live, but 12V pins don't give anything. Thinking of PSU board having an issue with that. Do the LED drivers have their own transformer(s) or are they related to this 12V output? Any suggestions on this? All the caps look fine, but I haven't tested them in any way.
