Spraying anything around display could be a disaster for the display.
Think I used Detoxit on the end of a Q tip
Then after it drys I use a silver conducting grease on the pins . USE VERY

I Mean if you can’t see it on there that’s about right.
Lastly change those A9 caps . Those caps have given me fits .
Ps could change the battery too . It’s right there in front.
