Should all three have voltage output even in standby, or just when it's on (green light). When my unit (spare one) it in standby/sleep (well, that's all I have since it will not power on I guess) I only have output voltage on two of the three. I found this out about 3 motnhs ago, but never looked further due to the holidays and such. After seeing this post, I have a new flame under my butt
PS, yes, I think I remember that all three are the same part, just different values of compnents in the circuit to set the output voltage.
The regulater is a national semiconductor part LP3965EMP-ADJ. All three regulaters are the same. The ADJ means adjustable based on external componets. The EMP designation is to get the right physical configuration, SO223-5 case if I remember correctly. They are $2.88 apiece from Digikey. The problem is in the removing of the bad SMT components and replacing them. Genrally need some special equipment or someone with experience in the field. I am going to look for the later in my area.
