If you can do it, just change the bad memory

do you know why the rise in temperature causes the chip to work again?

@dexranger

I believe, in this case: The heat melts the solder, and fixes cold solder joints. Otherwise, if the chip is faulty, this fix will not work.

@@jkftech there is only amber light, no fans are working. After it is staying such 20min and becomming warm, it starts and boot OK, somethimes it don't but then electricity reboot help. This unit is small and has inside 3x big chips that needs radiator (means generating a lot of heat). When there is amber light, only one is hot - means power goes only to one chip - and probably under this chip there is problem with connection I belive... probably it would need BGA reballing, but there is no stencil available to it... when it become hot it sometimes connecting and run - it is what I suppose... do you have other ideas or findings on this unit?

Yes it won't last, the point of the video is to let you know the IC that has problem. Regarding the ic purchase you can get it online alibaba, aliexpress, eBay, Amazon. If you want new chips etc. We only sell refurbished
