This S21 Plus came in for No Power Data Recovery.
No short before prompt to boot.
When prompt to boot, it would draw instantly around 300-400mA and kind of just hang there.
Using thermal cam, I found RAM seems to be shorted.
Pulled RAM & found the prompt to boot was different. It only drew around 200mA and no more heat around CPU/RAM.
After pulling RAM from donor board, prompt to boot behavior was the same as the customer's board. This gave me hope that RAM was the issue
Installed the RAM I got from the donor onto the customer's phone & it booted! But it would restart right away. I was using the DT880 to boot it.
After plugging in the battery, the device was stable & I was able to pull the pics/videos for the customer!
Win!
So glad I didn't have to pull CPU in all this 🙌
If you have a Seek Thermal Cam, you're missing out if you don't have a VCC Seek Stand: https://www.vccboardrepairs.com/buy-seek-stand
Injured Gadgets just got these back in stock, so get them while you can!
It can take us a while to build these out sometimes, so they're sometimes out of stock for a while, but we're working towards always having inventory ready to build more as they sell out.
This stand makes using a thermal cam so easy. So much better than any other thermal solution on the market.
It allows you to get real close up (using my Macro Lens), and easily find where the short is coming from.
Plus it's hard free, so you can have your hands free to try to boot the device from DCPS, while having an image that is in focus & not moving around.
You can even record a video through the app, while you inject voltage into the short, so you can go back & see exactly which component was it that was heating up.
Save yourself lots of time by getting a Seek Cam, Stand & Macro Lens! ...
