rx570 shapire nitro , no video no fans , I suspect the voltage regulator
Hello, I have a Sapphire Nitro RX 570 4GB graphics card. Currently, it's not displaying any video, the fans aren't turning on, etc. There's just a strange beeping sound coming from some component.
Anyway, I've been troubleshooting it, following some videos. I measured several voltages and noticed that the 5V supply on pin 4 of an integrated circuit is missing. It should be outputting 1.8V. Since I couldn't find a schematic for the board, I used videos of similar boards and discovered that the 12V to 5V voltage regulator only has a 12V input, and the 5V output is actually only delivering 0.8V. I accidentally bridged the 8-pin IC, causing pin 4 to receive 5V. The beeping stopped, and the 1.8V was present on pin 6. I'd like to know if someone with more experience can guide me. I think the LDO regulator (I believe it's called) is faulty and should be replaced, but I'd like another opinion to be sure.
Note: When I bridged the pins, the beeping stopped, and the GPU started overheating, which it wasn't doing before.
