Was anyone ever able to run AHT or ASD on these 2010 kernel panic unit
Hi folks, I am trying to keep 2010 15”machines in circulation: I have been trying my hand at refurbishing these machines which kernel panic, by replacing the Tantallon Cap in the GPU rail, to stop the random shut downs. It seems that 90% of the time I succeed, but I have 2 machines with new caps installed which after a few weeks started to randomly shut down again. I have been looking for possible other causes and fixes, but nothing seems to do it. Worst, I cannot even run ASD nor AHT on any of these machines for some reason, which seems to be a common problem with that year according to Apple forums . Does that mean that I actually have to replace the GPU chips in those units? Also I am hoping that someone can link me to a page where I can get help interpreting kernel panic report in general, or this one here in specific: nonymous UUID: 400E10CA-01CD-0007-6971-71A40DC343E0

Since the issue with these machines is random shutdown related to the GPY circuit, can anyone recommend a GPU testing software,or really any diagnostic software, so I can make sure that my machines will not fail due to Mux chip weakness or GPU failure down the road when stressed?

@arbaman, thank you so much for your help, I very much appreciate your input, and your confirmation on “Heaven” being a good tool. ( I was worried that I might further damage a board with such a program). Since exchanging the C9650 alone did not resolve the issue on some boards, your pointer to check the resistors around U9600 is just what I needed. Did you find that there are specific next weakest link in the chain on that GPU rail? And also, do you know how I can check caps while on the board? I have not yet found out how to measure capacitance yet…there are still so many gaps in my understanding…..but I will get past them with some help.
