hello, thanks for the replies, this unit was originally dead when i got it, found cold solder on transformer, then had an intermittant problem with no power, there was a hairline crack next to connector on power supply board, hidden under the black silkscreen of the screw hole., about 4 traces were affected. you can flex the power supply board violently to see the problem. troy _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp Help make your TechAssist online repair tips database better!
