Aqua-rite Gold Line Salt Generator issue

A few days ago the "Inspect Cell" was on, while i was turning the system off i noticed that the display would flash and "jiggle" a little when i moved the switch or pressed the diagnostic button, seemed like a loose or dirty connection.
I took the cell off and started a cleaning in a bucket with diluted Muriatic acid
This a.m., with the power off i took off the face plate and removed the the small PCB board from the unit , i used canned air to blow out the holes on the back of the board and wiped the pins coming off the main board with alcohol and gave them a little rub with some 2000 grit sandpaper.
The legs for the display board are getting pretty brittle and the "feet" on three of them are partially broken, the board moves a bit as you will see in the video.
I also slid the 3 way switch back and forth quickly a bit as it seemed a bit gummed up (this may be my downfall)
Cell was clean and i reinstalled. Plugged the board back in and powered up.
only Power light comes on (not even no flow)
Display shows 9900
Diagnostic button cycles display, and moving the switch from Auto to Super Chlorinate it changes the temp reading between metric and imperial but not the AL reading,which is set to AL-5 somehow I emailed Hayward, they said to turn off the power at the breaker for 5 minutes if that doesn't change anything the board "likely needs to be replaced".
i turned if off of about 4 hours while i re plumbed a pipe. After powering back up, same symptoms.
