One Loud Continuous Beep

Hello

Got a PS5 Console (CFI-1215B) off of Ebay for stopping in middle of game. I played a game on the system and it did stop in the middle of a game. Troubleshot the unit and found a large dry spot on the VPU. Cleaned the tarnish off and reapplied the Liquid Metal and added a Dot more.

I reassembled and started the system up fine and went to main screen. I was able to update the Software. I had no codes or problems. I also went through all the main screen opening and closing links.

I started a game and was playing. At first it was slow play and doing fine. Then when it would start to get faster play the screen/game froze and a Loud Continuous Beep started. I was unable to back out of game or turn the system off by the on/off button. I had to pull the power plug in order for the system to turn off.

I opened up the unit and looked at the liquid metal again and it was still spread out and in good condition. I reassembled and powered up the system again. I had no Codes being shown on startup. Tried playing game again and exact same thing happened.

Anybody know what this is and or have a fix for it?

Thanks

MJ
