Re: Dell 2007WFP Won't Power On

I believe the stuff on the regulator was from the capacitor, there is a little bit of it all around that capacitor. Do you think it is going to go out soon?
Maybe the capacitor has nothing to do...

Re: Dell 2007WFP Won't Power On

YES!
I replaced the 3A fuse with a 3A tube fuse from RadioShack and the monitor works!

Thanks for all your help!

Re: Dell 2007WFP Won't Power On

It is a little hard to make out but it appears to be 960T65.

Also is it possible to use the blade fuse or would that not work?

Re: Dell 2007WFP Won't Power On

Does radio shack carry fuses? I can only find 250V fuses. Does the voltage only mean the maximum voltage?
They appear to only have the glass fuses and the blade fuses.

Also the "blown"...

Re: Dell 2007WFP Won't Power On

The capacitor says 47uF 25V on it. Would it be ok to replace it with a 47uF 16V I have lying around? Also does anyone know if the monitor should start without the USB board in place? Because it...

Re: Dell 2007WFP Won't Power On

The 3A fuse shows 2000 ohms resistance. Is it good or blown? I already desoldered it :bash: because I thought it was blown since my dumb multimeter sucks so much.

Also the voltage regulator on...

Re: Dell 2007WFP Won't Power On

There is another voltage regulator on the USB board that is 3.3V (960T63). I wonder if they're the same... Also to help anyone in the future, the way to remove the bezel monitor is to pry it off by...

Re: Dell 2007WFP Won't Power On

I tested the burned out piece. The only short is from the top pin to the middle pin on the bottom. The resistance across the pins varies from 5 to 60 ohms and also varies depending on which probe...

Re: Dell 2007WFP Won't Power On

Please take a look at photo 3, at the top right of the logic board. There is a rectangular element with 3 pins on the bottom and one at the top. It looks very weird, sort of like it is slightly...

Re: Dell 2007WFP Won't Power On

Yes it is for the soundbar. What do surface mount fuses look like? The only fuse I know the shape of is the large one on the power supply. I tried putting only the 3 boards in (not the...

Hello,

I am measuring the voltage at the connector going to the logic board. It is showing 18V across the pins in the picture. None of the other pins show voltage relative to any of the other...
