Hi guys, just an update and need some more advice. I removed the two terminals and removed the unnecessary exposed copper track (should I remove the whole middle copper track). I chipped out the burned PCB and now there is no conductivity between the terminals.
I couldn't understand the point of the two thin tracks running down the bottom. But I have left it intact.
I should add I found quite a bit of dust and dead insects in side the chassis when I first opened it up. Could these be the initial culprit?
I need some help with figuring out what to use to fill the hole made. Would epoxy be ok? I couldn't find any good options from the local shops. All I have got is hot glue, but in my experience it doesn't give enough mechanical reinforcement. The pad on the left really needs it.
I have included some epoxy mix available at some local shops.
Thanks so much for the help everyone
