Re: Samsung LN40B530P7NXZA Polarized Picture Problems

I purchased 2 chips and either the first one was defective or I screwed it up because the second one worked like a charm. All the colors are back as if it was brand spanking new!!!

I searched around and saw...

I need some help from the knowledgeable members here. I was given computer with a DFI lanparty NF4 motherboard that had horrible artifacts on the screen. The former owner replaced the northbridge fan by himself which was not exactly the best repair job but it worked. It is NOT the video card because he replaced that first thinking it was bad.

Now here is where I screwed up and need your help. I started turning it into a server. Video artifacts mean nothing to a server. While tinkering around I found a part that looks like a capacitor that had some "gunk" around it. Part...
