Chosen Solution
The ps4 started having this problem when it turn on and quickly turn off. So I purchased another power supply from ebay So I went to install the power supply and when I turn on the ps4 it started loading but a strong burning smell started coming from the power supply and 15 seconds later it turn off. So I message the seller and told me that it could be a motherboard issue that could have shorted the power supply. Any ideas on what’s the issue or solution?
Maybe overheating, try to clean your fans and look for dist inside your ps4. And did not the Chinese power supply damage anything in your system??
