[QUOTE="FTAaddict, post: 483893, member: 279756"] Hello to all members, I'm a newbie here but not new to the satellite hobby, I actually live in the USA but thought that I could get some better help from you pros, I've read many of the posts here and see that you are a bunch of great people. I can't find any help here in the USA for these Manhattan Rx's, they aren't very popular here. Anyway, I was hoping somebody could help me figure out whats wrong with a dead PS in my Manhattan Skyline 1000, I know it's an oldie but it's a goodie to me, I hate to see it end up as a door stopper. LOL I don't have a lot of experience in electronics but enough knowledge to do the hands-on work if I can get the right guidance. I suspect a bad cap from what I've read in my research. I actually have 2 of these 1000 models so I swapped in the other PS to make sure the mainboard is working and it does work. I took voltage readings on all voltage taps and they all average about half of what they should be, this leads me to believe the LARGE cap ahead of the transformer may be the problem (Samwha 400V 47uf), I haven't checked it yet with any meter, I just ordered a Digital Capacitance Meter but I won't have it for another week. I also have a VOM and know how to use it. My question for you gents is; has any of you had any experience with a Skyline 1000 power failure and can offer any suggestions or guidance in how I should approach the repair? I've never checked a cap before and could use your help. Thanks to you all :) [/QUOTE]
