dust removal ?
mechanical constraint like a track which is weak and sometimes it does
contact some times not ?
electrostatic discharge ? some charges that were trapped in condesator have
been freed ?
Yes, maybe all of them.
But what i can check? I've removed the dust, with brush and air spray.
I also cleaned all the connector with a contact cleaner.
I'm thinking to check if there are some wrong voltages coming from the
psu, but i don't know where to check.
Someone has hints about this?
Thank you.
