Dell D620 Display issues

I picked up a dell D620 notebook second hand. I did a fresh install of the OS, installed and updated all drivers. I noticed there was some pixels that were going crazy. There would be a line across the start bar, and a block of miscolored pixels on the bootup screen. If I booted into safe mode, they would not be there. Also, when the notebook is hooked to an external display, they will show on the laptop, but not on the external LCD. I replaced the entire LCD, with a new Glossy 14.1 and new inverter, and it did not help at all. I also pulled both sticks of ram and replaced with 2 new 1GB sticks. Sometimes it seems to be fine for a few hours, and then it will be back again. I am pulling my hair out trying to figure this out. Think the LCD cable may be the cause?

 

Pictures? It seems like your machine is showing signs of an impending GPU failure... do you have the NVS110M?

 

I have the GMA 950 card in it. First thought that I had was a failing GPU, but if that was the case, wouldn't it show the same on the external lcd? I will get some pictures up, right now it's in one of it's "acting normal" modes. will not take long, lol.

 

Oh, I missed that bit about the external LCD. You're right. Plus I've never heard of a GMA950 failing, so yeah...

In that case I'd agree with your initial assessment: it must be something between the GPU and the LCD; maybe a connection, maybe the inverter, maybe the display itself...
