Oh my gosh. these are the absolute WORSE power supplies ever seen in LP340s. wholy crap. they only got 4 lytics, one is the tank cap, and the other 3 are 100uf at 25V caps.
all 3 bad, high in ESR with over 30 power supplies i worked on.
the one in the boost converter goes bad, takes out the mosfet, which in return blows the supply beyond repair.
another one by the VIPER SMPS controller goes bad, and blows the controller, a transistor, 3 diodes, a fuse, and the opto-isolator. still fixable. and antoher one goes to the current regulator for the lamp, which is less critical, but is if you like lamp life. :-)
man oh man.
