Hello:
I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.
I started on the ACER:
Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.
I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap... -
Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.
I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :
D608, good
D618 RF101L4S, good (See warning 1 below)
D619 RF101L4S, good (See warning 1 below)
D865 RF101L4S, shorted (See warning 1 below)

Hi,
today I got Razer Blade 14, Ryzen 9 6900HX and RTX 3070Ti.
Laptop was completely dead. I found shorted CPU VRM mosfet, shorted 19V mosfet and blown battery fuse.
I replaced it all, but still on CPU coil where mosfet was shorted I got very low resistance, near 0 ohms. On other CPU coils I got around 3 ohms.
Laptop now raises voltage on whole board, but still nothing comes on the screen. CPU gets 0.7V on all coils except the shorted one. CPU gets only slightly hot, below 40 C.
I removed coil and injected 0.7V, it draw around...09-27-2024, 12:44 PM -
