I've got a 35mW HeNe Laser + Power supply that I

next to nothing. It seems to be having some problems - the laser
(somtimes) blinks a few times when I first turn it on, and then stops.
From the sound of the power supply it's either a loose connection (which
I doubt after opening it up and taking a good look around) or there's a
problem with the power supply.
I'm just looking for general guidelines.
You might want to have a look at Sam's Laser FAQ, and you might also want
to have a look at switchmode power supply section of the the
Sci.Electronics.Repair FAQ.
