I replaced the 3 caps just like the previous poster. I am a novice at soldering but it seemed pretty straightforward. Anyway, LED lights are still strobing. I must be the only one on the Internet this hasn't worked for.

Here are the pictures of the PC board. I replaced CD1, CD2 and CD3 (twice each). I'm wondering whether a better plan B would be to just wire in standalone 24V 6A power supply for 20 bucks.
Thank you very much.

Your board is different from mine. Did you replace all 3 caps with brand name, quality, low esr, 105C temp rated caps? Cheap Chinese knockoff caps are the shits. Are you sure all the LED's are working inside the panel?

Just as an update: our Aerogarden is still working after the recap.

This thread has been very helpful!

My Aerogarden (model 100744-BLK) has the same circuit board as the OP. I replaced the 3 caps (CD2a, CD2b and CD3) last year and that fixed the strobing LEDs but they've started strobing again and the caps appear to be good. It appears to me that the problem may be with L1 (an inductor), which is between caps C1 and C2 on the other half of the board. It seems to have leaked some thing on the board. Does anyone know what the spec of this should be so I can find a replacement?

Thanks in advance,

/human

That inductor won't be your problem. Did you also change that little cap on top of the transformer? The solder joints on the red and white wire really do not look good at all.
I guess you have to put that thing back together and do measurements. What do you mean by the caps appear to be good? They may look like brand new, but still can be bad. Did you use an ESR tester? Check the transformer maybe...

@stj :-) my bad

@CapLeaker, Don't have a ESR, what I meant was the caps didn't look mis-shapen and were less than a year old but point taken. Will check the cap above the transformer. I haven't unsoldered the transformer leads to test it, will do so.

I saw a suggestion earlier about using an external PSU to drive the LEDs. Can someone confirm that it's 24V DC @ 6A or higher. I could jury rig that perhaps.

Thanks,
