hello can anyone share me a boardview for this model? greatly appreciate it.
need to find capacitors value.

I have 5 faulty RX570 PowerColor VGA boards. All of them have the required power rails such as 0.9V, 1.8V, 1.5V for VRAM, and 3.3V for the bus. However, there is no 3.3V EN signal going to the VCCDI/VCORE power IC — it’s an IR chip, though I don’t remember the exact model. The fan doesn’t spin either. Unfortunately, I don’t have a boardview or schematic. Please help me. Thank you very much....07-10-2025, 10:34 AM -
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 -
Hello,
I have problem with my graphic card GV-N3060GAMING OC-12GD.
2 smd elements are missing.
I've already bought a boardview but it's not complete - that specific area is not attached. I tried with different similar models but without success.
This is my PCB
And this is screen of boardview
As you see those missing capacitors or resistors are not on boardview.
Also i compared every single transistor from boardview to real card and everything is related.
It seems that this one is like extra.
Could anyone...08-09-2025, 10:26 AM
