Emax

Yes, definitely open the emax up and look for any obvious signs of loose connections. The screen on my emax was behaving strangely and reseating the connectors to around the analog board and the front panel board seemed to do the trick. Just be carefull poking around the powersupply, from what i understand larger capacitors in the power supply can hang onto a charge for quite a while and remain dangerous.

            I have had to replace the power supply on my Emax HDSE twice now.  

Mine just failed completely (of course at a gig), was not 

intermittant.  I'm thinking it may not be the power supply.  Maybe 

you have a weak connection inside.  Open it up and look for the 

obvious.  Also make sure the power cable or socket is not the 

culprit.  Also check that the fuse and fuse holder socket is making 

good connection.  If it is shutting down after powering up, it may be 

a componant heating up too high, then failing.  The price on 

the power supply has doubled (probably availability).  I've used EPR 

electronics. http://www.eprelectronics.com/  You will have to pull 

the power supply PC board to ship to them (fairly easy to do, just 

mark your wires or take close up pictures before you start).  They 

will send back a different one that is recondidtioned.  The one I got 

back makes the voltage selector obsolete (so it recognizes any 

voltage without having to switch the knob).  Hope this helps. -Alan
