Re: Aerogarden Ultra LED blinking or strobing grow lights repair
Wow, I was actually surprised at the relatively low lifespans listed for many caps when I was replacing mine. Shocking that more things are blowing all the time!
Good luck and happy hunting!

Re: Troubleshooting External Power Supply
Can you help me locate the bridge rectifier on this board? I'm not seeing the 4 diode configuration, although the LF102 appears to be square..?

Re: Troubleshooting External Power Supply
While I'm setting up another order, any other components I should consider replacing? I strongly suspect that the large cap was the culprit as it had some small leakage on one leg....Leave a comment:

Re: Troubleshooting External Power Supply
Thanks, yes that T4.0A 250V STA fuse is failing my continuity check. Dare I bridge that fuse to test? ...while I wait for a replacement to come by mailLeave a comment:

Re: Troubleshooting External Power Supply
Hey budm-
Thanks for the response. I had looked for a fuse, but I haven't been able to find one. Are you actually seeing an F1 on the board?Leave a comment:

Re: Troubleshooting External Power Supply
Hey CapLeaker- Can you explain how to do this? Possible without removing the big cap again?Leave a comment:

Troubleshooting External Power Supply
Hi all-
I had a 12v 12.5A external power adapter fail the other night after being powered continuously for 6-8 years. I've replaced a few capacitors in other projects now, so I decided to replace the 6 obvious and large caps on the board, but this didn't fix the problem. I'm getting 0v out of the supply when powered up.
When replacing the caps, I used same spec replacements:
1. 25v 820uF x3
2. 35v 220uF
3. 25v 330uF
4. 420volts 150uF
Any help in further troubleshooting would be greatly appreciated. Pics of the... -

Re: Aerogarden Ultra LED blinking or strobing grow lights repair
Thanks, stg. I can't find either exact series, but these values are available from a variety of manufactures. Am I correct to assume the capacitance is measured in micro-Farads?
10 μF
50 VDC
470 μF
35 VDC
Looks like I can get Kemet Aluminum Organic Polymer replacements for $0.64.Leave a comment:

Re: Aerogarden Ultra LED blinking or strobing grow lights repair
Hey redwire-
In looking at the light board, I count 304 LEDs and 11 resistors (photos attached). They're permanently bonded to the aluminum board for cooling and stability with what looks like epoxy.
I'm still interested in troubleshooting this and admittedly a complete novice. What would you suggest for next steps? I have various voltmeters, but no oscilloscope available.
(I have not replaced the three polymer caps as I don't know how the three numbers on the top translate...Leave a comment:

Re: Aerogarden Ultra LED blinking or strobing grow lights repair
Hey CapLeaker,
I'm seeing the same issue with a different board revision from the same year. I don't have those large caps like on yours. Not sure how to find the guilty caps.
I removed one of the heatsinks and took a bunch of pictures. I would appreciate any help you could provide to target the culprit.
