Re: Dell 2007fpb no power
I'm pleased to report that my 2007fpb now runs from an external supply, the HP laptop supply works perfectly at 18.9 V measured across the test points TP 711 (+) and TP 712(-) .
It's also a LOT COOLER so in improvement I think.
Thanks for the help all.

Re: Dell 2007fpb no power
Hi all,
I've ordered a HP PPP014S 18.5V / 4.9AMP POWER SUPPLY and isolated the mains input end for safety by lifting the fuse. I hope the 20v mentioned earlier was measured on the secondary side. This monitor does have P.I.P for multiple inputs and 4 usb's so I think a little more than 12 will be ok, thanks for the advice and I'll post the results when the psu arrives.Leave a comment:

Re: Dell 2007fpb no power
My Daughter is on holiday with my decent camera, I won't waste anyones time with poor quality webcam pics. Besides I really don't want to repair this board, as I said I would rather just attach an external unit.
I'll put 12v on the test points and see if it powers the rest of the unit. I suspect looking at the circuit i'll lose the ability to turn it off by the soft touch panel button, but that's not important to me, I can pull the plug.
Thanks for your time.Leave a comment:

Re: Dell 2007fpb no power
sorry, forgot to mention it's the same psu (identical part number) as in the earlier post with all the pictures and info. The capacitor I'm thinking of is at the top of pic 1,and the tracks run down the right hand side to TP712 and TP711.

Re: New Members - please post your introductions here
Hi all i'm Ken,
I've been tinkering with stuff that plugs in, lights up or burns fuel since the age of about 10 ! (long time ago now) I grew up with acoustic couplers, paper tape, commodore pets and built an rs232 interface for my 1st Vic 20 so I could chat online with a neighbour (before online existed as we know it) , I speak DOS and dream in Hexadecimal of ways to simplify ms windows so it works properly!
In conclusion = GeekLeave a comment:

Re: Dell 2007fpb no power
Hi everyone, I've just found this old thread and wonder if someone could point me towards the solution above, I would love to revive my old 2007 FPb but my eyes aren't good enough these days to fault find the entire psu.
As I remember the monitor began flickering one day, then burning, and then dead, the fuse is ok as is the bridge. The 8 pin I.c Seems dead however.
I would really like to just hook it up to an external supply, Do I just connect to the + & - behind C711 ?
Thanks in advance...Leave a comment:
