That could be kinda tricky, we could only guesstimate. Or somebody with the same display can possibly desolder one and measure.

I am curious, are the parts in that section damaged or missing?

If there was the silicone, I would guess maybe damaged

Default Re: Dell 2007FPB teardown

In my case (2007FPB) it was R50 on the USB board that was open. Labeled as 01C (10K Ohm).

Managed to pull one of the pads off when I was desoldering the resistor, but there is another spot just next to the pad I was able to get to.

Not sure why Dell felt the need to gunk up this area with the silicone. Would have been a TON easier to troubleshoot without it.

Threw a 1/4watt 10k in the spot and everything appears to be back to normal.

Yes these are old monitors, but they're still a good looking unit for doing standard office work. I've got 2 of them, one left and one right of a 24" Apple somethingorother (got it free, also a nice monitor)

Does anyone have any suggestions for how to remove the white glue?

You just have to carefully scrape it off with something plastic. There's not much else that will do it. I don't think there's any chemical that would take care of it and not hurt the board.

Thanks. Rubbing alcohol didn't do anything. Was thinking of applying a caulk remover. This stuff is on there pretty good. Hard to believe I can get it clean enough to see what's underneath. Just assumed somebody found an easy solution.

My favourite tool - dental explorer - works fine

My second 2007FPB took a dump earlier today. Immediately went to the resistors and there were 3 of them pretty far out of spec, a 2.7k 47k and 75k. Oddly the 10k's that were bad on my other monitor showed fine. I'll have to look at the pictures I took to see if the boards are different. But its back up and running like it should be.

I do know my eyes and hands are getting too old to deal with SMD stuff with the equipment I have on hand...that's for sure.
