I tend to leave my 9 LEs powered up 24/7 during the season, and after 5 years of faithful service I discovered one of them DOA tonight.
Wife had called me earlier in the day saying that the circuit this LE was on had tripped and extension cord was hot, so I'm sure its related, but none of the other LEs on that
circuit were harmed.
No 3/5v leds lit, nothing. Fuse was blown so I replaced it....everything still dead. No burn marks or bad smells on the board...just a the usual yellowed flux from the soldering. Got 120v at the transformer, but not sure I'm measuring tap on the other side right...not showing more than 2.9v DC if I measure between pin 6 and the rectifier leads. Swapped it out with a new one, but still same readings. Got nothing measuring from center lead to edge lead of either of the voltage regulators either. Not really sure how to test the rectifier.
Tomorrow is the big crowd, so pulling an all-nighter to get a spare LE kit soldered up, but would like to figure this one out when time permits. All suggestions welcome.
Thanks.
Mike E.
