I've bought 2 of these from Ebay now.They both had the power button fail and fall into the casing.Its an easy fix.$500 + monitors for less than $100.

I had to upgrade my old video card to accept DVI via AGP,but what a difference!A subwoofer added on is great.These baby's are BIG,but worth it. I think HP unloaded the defective ones to various wholesalers on Ebay.I like saving $$$$ and its worth it,with a little fixing.

ON EDIT:I have yet another one coming on 3/04/08.I'll post some before & after pictures of the simple repair next week.

Go here to replace your CCFL & EL inverter boards,on defective LCD monitors.They are Top Quality and exact.My last(3rd) HP F2105 monitor fix required a board replacement.Grrrrrrrrrr .But still,at $60.00 and a easy power button repair,I was happy & amazed.The HP F2105 takes the 6 CCFL board.

This 3rd one was more involved than just a power button.It kept shutting down after 3 or 4 minutes.The backlight would flicker right before going black.I could manually adjust it through the menu,but the brightness and contrast had to be at 100% to keep it displaying properly.But I still only got
about 10 minutes before the black screen again.
I found this:

HP F2105 inverter

Its working great now,but it cost me $100.00 and a half hour to install.

Still cheaper than $500.00 for a new one.
