Re: Dell 2007WFP Won't Power On

@MEB, I know you've probably read my reply 2-3 pages before, but I see fit to give you an advice here, even as non expert to non expert.
So, I don't know what is the situation with the inverter board you have and why it is blowing its fuse, but if you have worked that out, I can advise you to check the two voltage regulators on the logic board (top right corner). If they are OK and you don't see any shortage to ground (except their own one) then your logic is most likely alive.
I've got my hands on 4 dead displays of these at work and...

Re: Dell 2007WFP Won't Power On

Actually I already found 3 spare boards with LM2596 and it is working like a charm for now.
They seem to be some kind of integrated PWM or so, as they are not producing any heat at all, but I doubt if this will continue if the monitor is heavily used in the summer.
The best ting is that they have wide input voltage range and can produce manually configured output voltage at 2A stable if what was written is true.
And they were pretty cheap, too - like 1$
I'm planning to mount them on a plastic board which will replace...

Re: Dell 2007WFP Won't Power On

Hi guys,
I'm having two of these monitors (2007wfpb) and they both failed their USB boards. On one of them the USB board was kind of working as it was flickering its voltages up and down (it was not able to power up the LCD at all), but this behaviour helped me to measure the voltages that are needed and are going out of it.
Anyway, if your logic board is alive, you need all 3.3V, 5V and 12V to be fed to the logic.
I gave it a try using a spare computer PSU as it has all required voltages.
So I fed them to J8 as shown in...
